In Car Mechanic Simulator 2021, players can restore cars that are available in the game, whether if it is pre-installed, came from the downloadable content (DLC) car packs, or downloaded as a car mod from the Steam Workshop, using more than 4,000 car parts.
They can either sell it for additional profit and for future car projects, as well as added car parts and upgrades, or keep it as part of their garage collection.
They can also repair or restore different kinds of cars, ranging from classic Americana muscle cars to compact cars to sports cars to full-size sedans to hatchbacks to grand tourers to minicars.
One of the said cars that are already installed in the game is the Salem GW500, or in real life, it is the Ford Focus RS, a high-performance version of Ford's Focus compact car. The said version was manufactured from 2002.
How to Restore a Salem GW500
Players can find, and buy, the Salem GW500 in the game's Junkyard, the Car Auction, and the Car Salon.
Once they have purchased the car, according to Pityku Customs' YouTube video, they will wash its body and interior in the Car Wash, then they will transfer it to one of the Car Lifts that are in the Garage.
From there, they will drain whatever oil that is remaining inside using the Oil Drain machine, as well as its other fluids such as the brake fluid, the coolant, the power steering fluid, and the windshield washer fluid using the Drain Tool.
Then, they will disassemble the whole car, and get the parts that can be repaired or replaced, until what is left on the Car Lift is the body frame, which they need to repair using the Wielding Machine, while having its interior detailed.
Then, they will repair the parts that they can still use in the restoration project by placing them on the Repair Tables that are in the Workshop. From there, they will play a minigame where they need to hit the green tabs in order to fully fix the parts.
On the other hand, the parts that are impossible to be repaired will be sold instead for additional Credits and Scraps, and they will be replaced with new parts. If they want to increase its Tuning percentage, they can replace them with Performance Parts.
Once they got the repaired or replaced parts, they can now reassemble the whole Salem GW500, starting with its engine, which is a I4 DOHC 4x4.
In order to do this on the Engine Stand, they will need the engine block, the crankshaft, the pistons with their rings, the crankshaft bearing caps, the rod caps, the oil pan, the oil filter, the flywheel, the clutch plate, the clutch pressure plate, and the clutch release bearing.
They will also need the engine head, the camshafts, the camshaft caps, the spark plugs, the cam gears, the timing chains, the engine head cover, the timing covers, the ignition coils, the fuel filter, the intake manifold, the throttle, the exhaust manifold, the fuel injectors, and the turbocharger.
They will also need the idler rollers, the water pump, the serpentine belts, the belt tensioner, the crankshaft pulley, the alternator, and the power steering pump.
Once they have finished building the engine, they will remove it from the Engine Stand and put it inside the car's engine bay using the Engine Pulley.
Then, they will install its internal parts such as the gearbox, the starter, the battery, the reservoirs, the brake servo, the ABS pump and module, the radiator and fans, the air filter with its base and cover, the ECU type A, the fuse box and cover with new fuses and relays, and the fuel tank and pump.
Then, they will install the rest of its parts, including those for the exhaust pipes, the suspension, and the braking system, as well as the wheels, the body kit, the lights, the windshield and other glass panels, and the parts for the interior such as the seats and the steering wheel.
Once they finished reassembling the whole car, they will fill it up with a new batch of oil and other fluids, then they will paint the body with the color of their choice in the Paint Booth.
Then, they will move it to the Test Path room to realign the lights and the wheels, as well as to test the newly-installed braking system.
Then, they will transfer it to the Dyno Test room to tune up the gears in its gearbox and perform a dyno test to check the engine's performance. Once they are satisfied with the results, they can now test drive their own Salem GW500.
