This guide includes everything you need to know about My Summer Car.

One thing you'll notice about My Summer Car, you're going to need to drink a few berooskis otherwise there's a chance there may be a keyboard going through the wall.


You might want to run to the store in the van to stock up on food and drinks before you start building the car. The van can be found at Uncle Kesseli's House and you'll need to get the keys from him when he's in. In order to do that, there is information on how to get the van. If you can't get the van, use the boat, moped or tractor to get to town. You might also want some way of cooling yourself down, because you will get very, very hot and frustrated from building and playing a lot.

Before you leave, load up your vehicle with canisters. A diesel canister (black) is in the barn where the tractor is at. A spare gasoline can (green) is in the back left corner of the garage. When you're at the store fill up the fuel tank of your vehicle and both of the canisters. From the store, make sure you buy everything from the left wall. The alternator belt, multiple canisters of each fluids. They will be important for building and starting the engine for the first time, so don't be afraid to spend almost 3,000 mk.

Important Extra Information

Before you leave to go to the store, it is very recommended to go install the driver's seat. After you do that you can take the boat to the store so that when you return you have a higher chance for the van to spawn to go get the wheels and other things. (i.e. GT parts that are recommended and the rpm gauge can be found around the map, use their respective wiki pages to find them.

  1. Depends on route and driving skills.

Starting the van

(OUTDATED, The van no longer spawns when you have just started the game, use the boat to get the the store and back, or the tractor, though its much slower)

To start and drive the van, get in by jumping into the seat (you should automatically crouch when entering the cab of any vehicle). Start the van by left clicking on the ignition (left side of steering wheel), then wait for the glow plug indicator to turn off before clicking and holding down to crank the engine. The same procedure applies to other diesel engines in the game. Headlights are to the left of the radio near the gearshift. Disengage the handbrake by holding right click, do it again if the parking brake indicator is still on.

Make sure you turn off H-shifter at the main menu if you're using a gamepad or keyboard and mouse. By default; X is clutch, G to shift up, B to shift down.

Finding the store

To reach the shop, turn left at the first three way junction at the end of the dirt road leading to the player's house, just after the railroad tracks. Follow the dirt road down to a four way intersection and turn right, a paved road (the highway) should now be visible. Turn left and enter onto the highway. After that, take the fourth left-hand side exit to reach Peräjärvi (the second exit leads to LoppeFleetari repair shop), the shop is the first building on the left (you should be able to see the fuel pumps).

If you want to use the boat to get to town, turn towards the island and aim a little bit to the right, once you get closer, a church tower will be visible. Using the boat will mean taking individual things of store items to the dock.

Warning: There could be a police checkpoint on the highway. If there is, pull up and take the breathalyzer test. Make sure to also drive within the speed limit (80 km/h for van and truck, 100km/h for other vehicles), and to always wear a seatbelt. When driving with the moped, make sure to wear the helmet. If you violate or break any rules, you will be fined, which can prove to make your early game very difficult.

There are few other ways to get to the shop by driving, but the route above is the fastest and safest. The entire road map of Alivieska can be found here.

Note: You might also want to visit the Abandoned Mansion to get the starter wheels. The mansion is located near Loppe, just after a small bridge. Remember to visit it at night (to avoid the wasp nest) and bring something that can open the locked doors, such as a beer case or a sledgehammer. These wheels are unlikely to pass inspection unless you install new tires on them. These wheels aren't the best, but they will prove very useful in your first rides aboard the Satsuma.

Eating and drinking

To drink beer and eat food, look at the beer/food and press the action button (default F). You can also drink from the kitchen or bathroom tap by turning the tap on, then crouching in front of it (default C) or bending over into the water stream (default Q).

Making money

To make money, there is a barn to the right down the road from your house. Inside is a chopping block and an axe which you can use to make money. Click the log stack to put a log on the chopping block. Click the axe, hit action button (default F), then right click to swing.

Other ways of making money include collecting bales around the map and deliver them to a farmer.

There is also a tractor in the barn. You can use this to tow your car by driving the tractor near it, then left clicking a tow hitch. Left click again to disconnect. You can also use the forklift to pick up your car using the front hydraulics lever from the right side of drivers seat. Don't lower it too far or it will glitch up the tractor.

Saving the game

To save your game, go to the nearest toilet and select "Save & Quit"

If you damage the body of your car, you can repair it by doing the following:

  • Navigate to C:\Users\Username\AppData\LocalLow\Amistech\My Summer Car.
  • Delete meshsave.txt from the folder.

Your car bodywork will now be repaired with your work intact. This will not replace broken windows or parts that have come unscrewed as a result of damage, and food you have eaten prior to reloading will still be gone.

Make meshsave.txt a read only file if you want damage to be repaired upon reloading.

Note: Delete the file manually or remove the read-only property before starting a new game or it will result in an infinite loading glitch because the game can't reset the file and continue the loading process!

Building the Satsuma

Before building

There are some things that could save a lot of hassle during and after the car assembly:

  • Most damageable parts are in critical condition at the start of the game. These parts can be serviced at the repair shop, but the smarter, though slightly more expensive option is to buy new ones from the repair shop shelf. Replacing everything will be very expensive, but all parts will eventually get replaced anyway. The easiest way to make a quick buck is to take the wrecked cars to Fleetari, but there are also other ways to make money.
  • Ordering the fuel mixture gauge and ratchet set from the parts catalog will prove very useful for the initial assembly of the car, as well as for tuning it later on. In total these items will cost 908 mk, and will take some time to arrive. This will also require two trips to Teimo's Shop; first to take the envelope to the post box, and later to pay for and pick up the packages when the shop is open.
    Note: The envelope should be taken to the store at the same time as the initial grocery trip, as the payment will only happen once the packages have arrived at the shop.

Getting started

Below is a complete list of car parts with their bolt sizes and quantities required for the car to run, for example: 6x9mm is 6 bolts/nuts with the 9mm spanner or ratchet.

Press F to open the spanner or ratchet set and then press 2 to enter tool mode, press 1 to go back to normal mode, pick a spanner or ratchet with LMB while in tool mode. Spanners and ratchets cannot be placed back inside the sets, the normal hand mode will still function normally regardless of whether a tool has been picked up or not.


  • Alternator - 1x7mm, 1x10mm, screwdriver
    • Put the alternator belt on before you tighten the alternator. Tighten the two bolts to secure the alternator, then adjust the belt tension by scrolling the mouse wheel while looking at the alternator to change the alternator position. Rotate it until the pulley is touching the belt, then tighten the screw.
    • Once the engine is installed and running, come back and properly adjust the alternator position with the engine running by loosening that screw again. Loosen the belt tension (scroll down on alternator) until the belt starts to squeal, then tighten it just enough it stops. If your alternator belt is too tight it will eventually snap. You can buy a new alternator belt at the store if yours is worn down or has snapped.
  • Alternator belt
  • Engine plate
  • Starter - 2x7mm (leave the front bolt untightened later for wiring, otherwise you will have to untighten again later)
  • Carburator - 4x8mm
  • Headers - 5x8mm
  • Flywheel - 6x7mm
  • Clutch pressure plate to clutch cover plate
  • Clutch disc to clutch cover plate
  • Clutch assembly - 6x6mm
  • Oilpan - 8x7mm, 1x13mm
  • Inspection cover - 4x7mm (shared with gearbox)
    • You can remove this inspection cover later for tuning
    • This part is not required and the bolts can be tightened without it being installed
  • Gearbox - 6x7mm (4 of which are shared with above), 1x10mm (lower middle of engine block, right below headers)
  • Drive gear - 7x6mm
  • Motor hoist to block - 2x10mm
    • Lower the hoist, and align it with the hoist notches on the engine. The hoist is in the correct position for tightening once a faint clink can be heard. Tighten the bolts and the engine will be attached to the hoist.
  • Adjust valves - screwdriver
  • Rocker cover - 6x7mm
  • Fuel pump - 2x7mm
  • Airfilter - 2x6mm
  • Oil filter - by hand (scroll)


You may want to jack the body up off the ground using the floor jack. Or you can push the car inside of the garage with the blue van or tractor (be careful to not damage the car's frame)

It is recommended to jack up the suspension from the front if you can, as it tends to tip off as it gets weighed down by installing new components. Otherwise just be mindful as you go.

Alternatively you could jack the car up and build the suspension and push the car into your garage, giving you access to the underside easily.

  • Sub frame - 4x10mm
  • Wishbones (2) - 2x10mm each
  • Spindles (2) - 1x12mm each
  • Steering rack - 4x9mm
  • Steering column - 2x8mm
  • Steering rods (2) - 1x12mm each (shared with struts, install them before tightening)
  • Disc brakes (2) - 1x14mm each (shared with halfshafts, install them before tightening)
  • Halfshafts (2) - 3x9mm each (Shared with gearbox, but it doesn't matter if you tighten them before you install the engine), 1x14mm each (shared with disc brakes)
  • Struts (2) - 4x9mm each, 3x10mm each, 1x12mm each (shared with steering rods)
  • Steering rod adjustment - 1x14mm each
    • The adjustment has 120 clicks total travel stop-to-stop. Turn both of them out all the way to the stop and then bring them back the other way with exactly 60 clicks. This is dead straight-and-center.
  • Trail arms (2) - 2x12mm each
  • Coil springs (2)
  • Shock absorbers (2) - 1x12mm each, 2x6mm each
  • Drum brakes (2) - 1x14mm each
  • Wheels (4) - 4x13mm each
  • Mount the engine
    • Move the motor hoist to the engine bay, lower it carefully and when it is in the correct position 3 bolts should appear at the motor mounts for you to tighten with an 11mm spanner/ratchet.
    • Warning: Be careful when handling the motor hoist when the engine is attached to it, sudden movements may send the engine flying across the garage, requiring it to be re-attached.

Finishing up

Fill up the car's fluids by unscrewing the caps on the engine components, then holding the containers upside down over them until a white bar appears (the fluid containers don't have caps). The clutch cylinder uses brake fluid. The gas can, coolant, brake fluid and motor oil aren't infinite. Tighten the caps again when you are finished. You can also pee in your radiator if you want.

Note: Buy at least 3 bottles of brake fluid as the two brake reservoirs require a full litre each, and the clutch reservoir 500ml. The reminder will be useful for topping up your fluids as they are slowly consumed over time. If you're not very familiar with the Satsuma it's best to get 4 or even 5 bottles as the brake lines will steadily leak fluid unless you tighten every single nut.

Starting the car for the first time

To successfully start your car, make sure you have filled all oil, coolant, and fluid reservoirs and have installed the alternator belt. To start a car (especially a Datsun 100A or other cars with a choke lever), pull the choke all the way up, located below the radio on the dashboard meters, holding the left mouse button. After that, start the engine and rev it several times without revving it too much, if you don't want the engine to overheat. Holding the right mouse button on the choke, it pulls itself all the way out. Make sure to pull it off, because, when driving the car for the first time, the engine will overheat while driving.


Now that the car runs perfectly without any problems during/after assembly whatsoever, the next step for it is to get it inspected. Before this, however; there are still a few things left to do:

  • Go to the tractor at the woodshed and pick up the warning triangle, it can be detached from the back of the tractor by pressing RMB. The triangle must be somewhere inside the car during the inspection.
  • Make some money, 1,900 mk to be exact if everything goes well, and take the Satsuma's wheels to Fleetari Repair Shop. The best way to transport the wheels is probably by using the van. Once there; leave them on Fleetari's desk and select the "Standard Road Tyres" option from the tyre list for 1,575 mk (with the 10% discount) and drive back home. Fleetari will eventually call the player's phone to inform them that the wheels are ready to be taken back.
    Note: The "Gommer Gobra" tyres will also pass the inspection, but are slightly more expensive.
  • Make sure that there are no aftermarket parts installed. There may be some exceptions as to what is and is not accepted, but in any case; aftermarket parts should only be thought about after the inspection.
  • Finally make sure that all parts are in good condition. If no replacements were bought from the repair shop prior to assembly, replacing them now can be a tedious task.

Now that the car is ready, drive to the inspection shop on any weekday (Monday-Friday) between 08:00 and 16:00. The inspection shop is located northeast of Teimo's Shop and behind the wastewater treatment plant.

Drive the car on the lift inside the garage, turn it off, put on the handbrake, and walk to the cheerful man at the desk. Left click on him once the paying prompt of 325 mk appears on the screen and wait for the man to do his work. Once he is finished; he will walk back to the desk, congratulate the player on their successful inspection, and hand out two register plates; they are attached to the front and back of the car without any bolts.

Congratulations! The car is now officially driveable. If, though, for some reason the car failed the inspection; it can be re-inspected as soon as the problems have been fixed, even on the same day. To figure out what could have possibly gone wrong; click on the inspection report on the desk and, by the off chance that Finnish looks like gibberish, click on the Union Jack at the top-right corner of the form to view it in English.

Note: The "additional notes" section won't get translated, but it is the same regardless of whether the car passed or not, and translates to something along the lines of: "This is a very beautiful car".


Tuning your valve-train


My Summer Car How To- Adjusting valves on a turned off engine

Visualised valve-train adjustments.

Remove the rocker cover to access the valve adjustment screws. With the engine running and warmed up to ideal temperature, adjust each one with a screwdriver; mouse scroll up tightens, mouse scroll down loosens just like the nuts and bolts. If the valves are too loose or too tight, they will make a 'ticking' noise.

The car performs best when the valves are as loose as possible without ticking. Be careful not to go too far in either direction or the engine can stall. If this does happen, immediately reverse whatever you just did before you forget which valve you were adjusting. Only then should you go back and attempt to continue tuning the motor.

The best way is to loosen each valve (mouse scroll down) until it starts ticking, then carefully re-tighten until the exact setting it stops again. Some valves are already in a too loose or too tight position, but will not start ticking until you fiddle with them. If a valve immediately starts ticking when you loosen it, keep loosening for another 5-7 wheel scrolls (or about a half turn on the screw head). If it stops ticking again the valve was in the 'too tight' position and you should proceed as normal (keep loosening until you hit the 'too loose' ticks and re-tighten) if it's still ticking after 5-7 scrolls you're in 'too loose' territory and should start tightening until the ticking stops.

Some great charts can be found here for the results of tuning your valve-train.

Tuning your carburator

Visualised carburator adjustments.

According to the lambda, the carburator should be set to 1Λ, that is, 14.7 kg of air per 1 kg of fuel. Such a multiple is called stoichometric. The greater the lambda number, the richer the mixture, and the smaller the poorer.

It doesn't matter if it's stock or not. Take the screwdriver from the spanner or ratchet set, find the idle screw, and then "unscrew" (mouse scroll down) 10-20 times. Get inside the car, pull the choke all the way out (by holding left mouse button on it), turn on the ignition and start the motor. Hold your RPM at around 3,000-5,000 by using the throttle pedal. Once the temperature gauge has reached the halfway mark it is at running temperature; release the choke by holding down right mouse button on it.

Carburator tuning.png

Get out and go back to your carburator. You can manually pull the throttle linkage to rev the engine and tune it while it is running. Rev the engine a couple times and pay attention to the exhaust. Dark smoke means you are running too rich, popping and cracking combined with the engine temperature steadily rising means you are running far too lean.

For now, being your first time tuning and this is still a stock car, we'll go for the richer end of the ideal mixture range. You can easily tell when you're in this range because the exhaust smoke turns a greyish white colour. Rich-en your mixture until the car blows dark exhaust smoke and then lean it out a bit, or if it is already dark, just keep leaning the mix until the exhaust colour changes. At this tune you should have plenty of low-end power to prevent stalling. If you still have issues you can hold the clutch and rev the engine gently before releasing the clutch for a bit more power; rev too hard though and the car will happily spin its wheels. This may or may not be a bad thing. If the RPM 'bogs' while taking off give the clutch a quick tap to let the RPM pick back up momentarily before the clutch re-engages. Again, this may result in a burnout but is preferable to stalling.

By tuning your carburator, you can enrich to improve your low RPM torque (less stalling, faster starts) or lean out to increase your high RPM power for better acceleration at top-end for things like the rally event, where you will constantly be down shifting for corners and generally always at high RPM. Be sure to re-apply your airfilter on the stock carburator if you have removed it for tuning.

A note for the stock carburator, if you have the fuel mixture gauge installed, a good solid value is 14 at optimum temperature. This gives the car enough power in 1st to avoid stalling as often, but still reaches high top speed. Once you have installed performance parts and gotten used to taking off without stalling, you can lean the mixture to 14.7-15.1; this will give plenty of high end power and allow you to hit the rev limiter in top gear, as well as accelerate very quickly, provided you shift late to keep the RPM as high as possible. The downside is low end torque will be very lacking; your car will pretty much always stall from a standstill without some feathering of the clutch, and you will 'bog' and accelerate very slowly below 4k RPM, down shift to get your revs back into the power band.

Common issues / FAQ

A few common problems people have and how to troubleshoot. The primary cause of problems is forgetting/missing bolts on components, but this guide should help you look in the right direction:

  • Car wont start & runs out of battery: Make sure your alternator is properly fitted. Ignition requires battery power to ignite; if your alternator belt or alternator is not connected properly you will not have a charged battery. Check those, make sure your alternator is pushed out from the engine by loosening the screw in the slotted section of the alternator bracket, and scroll the mouse wheel to rotate it to the appropriate position. See the alternator entry under engine assembly for more details on proper belt tension. Also check the distribuitor. If it's unbolted, the Satsuma won't start.
  • Engine makes a horrible squealing noise: You didn't tension the alternator belt properly. See the alternator entry under engine assembly for proper belt tension. If tightening the belt doesn't help, make sure that both alternator and water pump pulley spin. If either of them doesn't spin, you will have to get a replacement part from Fleetari.
  • Engine ticks while running: Your valves are badly adjusted. See the valve-train guide under tuning. Your camshaft might also be misaligned.
  • Cant get into gear: You most likely have a broken gear box or your missing the gear linkage.
  • Clutch is stuck open: This could mean you haven't filled the clutch master cylinder, make sure it's brimming with Dot4 brake fluid and try again. If it's leaking; check every nut on the clutch lining, as well as the cylinder itself. Make sure your handbrake is off!
  • Keeps popping out of gear while driving/is very difficult to get into gear: You have missed one of the bolts on the gear linkage, or one has come loose.
  • Brakes don't work: Make sure every nut on the brake lining is done up; see the assembly section to make sure you got them all. You may have to bleed the brakes, unscrew the brake line nuts at every wheel by 2 notches and go push the brake pedal for a bit (try not to run out of brake fluid though). Be sure to tighten each nut back up and try the brakes again.
  • Part X wont fit part Y: Certain parts are very selective on how you apply them, including the angle of attachment. In some cases, such as the exhaust pipe, saving and reloading the game fixes this issue.

Missing alternator belt - snapped and needs to be replaced.

  • Radiator starts steaming while driving: You've either left the choke pulled or your carburator tune is too lean for the radiator to keep up. You should stop immediately because as the engine overheats, it leans out the fuel mixture and makes the problem worse; ignoring it will inevitably result in broken pistons. If your car has been running fine and this suddenly happens, you may have snapped your alternator belt (alternator is too tight) and your water pump is no longer being driven.
  • Stalling in 1st gear: This is completely normal! Even if you use auto-clutch, when changing to 1st gear you are dumping the clutch in low RPM, this will stall a lot of cars in real life. Wait until you car has warmed up at least to the first mark on the temperature gauge, give it some gas in neutral and quickly put it in 1st to set off. You can lessen this effect by perfecting your carburator tuning (a richer tune has more low RPM power, so less stalling), upgrading the car's power, or letting it warm up to higher temperatures before setting off.
  • Engine backfiring or "exploding": Tune that carburator! See the tuning section above for that. It can cause permanent damage to your pistons if you don't alter the tune, which means a trip to the mechanic. If you are certain your carbs are tuned correctly and it is still backfiring, you could be leaning out from overheating, or your valve tune is off.
  • Engine "stutters" rapidly between full throttle and idle when gas pedal is down: Your fuel pump is dead. The empty bubbles of air that the pump is mixing into the fuel line are what cause the stuttering. The car is basically dead in the water in this state - push your car somewhere out of way, unbolt the broken part, chuck it into a swamp and find some way to hitch a ride home where you can plot a trip to Fleetari's the next time he's open. He only stocks off-shelf replacements for parts that are floating around "independent" in the world, not installed to your car.
  • Radiator's fan not working: This is normal. The fans only spin up when the car is too hot, however, if they still do not spin at high temps it's most likely because your alternator belt served its life and is broke. Buy a new one at the store. If your alternator belt is in working condition, make sure that you have properly wired the fan to the battery.
  • Car pulls to the side when driving: Your wheels are poorly aligned or you have bent your struts. The adjustment screw (14mm) is between the steering rod and strut. You must use the spanner set for the adjustment screw. Take both wheels to the end of their working travel (120 clicks maximum) and then align them by turning them 60 clicks in the correct direction. The airfield is a great place to test changes, if however you are too lazy, you can travel to the repair shop and choose the wheel alignment service. If your struts are bent, you can apply first aid with the digging bar found in your wood shed before seeking repair services or replacements. Pick up the bar, wield with F, point it at the busted strut (can still be attached), crank the hotspot with RMB, assess by eye whether the wheel is facing the ground roughly the right way, repeat until satisfied.
  • Dead battery: Use the battery charger to charge it, or buy a new one from the store. If the needle on the charger is slowly moving to the left when a battery is attached, it is still salvageable, fully dead batteries cannot be recovered.
  • Inspection failed due to fuel line: Tighten the 12mm bolt at fuel tank.
  • Inspection failed due to tires: You tried to pass the inspection with the rally, drag, or overall too worn tires. Only the standard or Gommer Gobra street tires will pass the inspection. The old stock tires can also pass inspection only if they are not too worn.
  • Inspection failed due to emissions: Your engine still needs tuning. Get the valvetrain and fuel mixture right.

  • When you are putting the engine in the car, you can use the motor hoist to lift the car up after you attach the 3 engine mount bolts and keep the 2 bolts on the engine connecting from the motor hoist.
