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 Emden Lotz, or in real life, it is the Volkswagen Golf Mk7 GTI, a variant of the small family car manufactured by Volkswagen in Europe from 2012 to 2020.
How to Restore the Emden Lotz
Players can purchase the Emden Lotz in the Car Salon, the Car Auction, and the Junkyard.
After buying it, according to Boblas' YouTube video, they will wash its body and interior in the Car Wash, then transfer it to one of the Car Lifts that are in the Garage.
Then, they will drain whatever oil that is remaining inside the car using the Oil Drain machine, as well as other fluids such as the brake fluid, the power steering fluid, the coolant, and the windshield washer fluid using the Drain Tool.
Afterwards, they will disassemble the whole car, and get the parts that they need to repair or restore, until what is left on the Car Lift is the body frame, which they need to repair using the Wielding Machine, as well as 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 said parts.
On the other hand, the parts that are impossible to be repaired can be sold for additional Credits and Scraps instead, and will be replaced with new ones.
Once they got the repaired and replaced parts, they can now start reassembling the Emden Lotz, starting with its engine, which is an I4 DOHC Turbocharged.
In order to build this on the Engine Stand, they will need the engine block, the crankshaft, the pistons with their rings, the rod caps, the crankshaft bearing 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 spark plugs, the engine head cover, the ignition coils, the fuel filter, the fuel rail, the intake manifold, the throttle, the exhaust manifold, and the exhaust manifold cover.
They will also need the cam gears, the timing belt, the alternator, the power steering pump, the timing cover, the water pump, the crankshaft pulley, the idler roller, the serpentine belts, and the belt tensioner.
Once they finished building the engine, they will remove it from the Engine Stand, and then using the Engine Pulley, they will install it in the engine bay.
Then, they will install the car's internal parts such as the gearbox, the starter, the battery, the reservoirs, the brake servo, the fuse box and cover with new relays and fuses, the radiator with its fan, the ABS pump and module, the air filter with its base, cover and clips, and the ECU type A.
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 of the interior such as the steering wheel and the seats.
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 its body in the Paint Booth.
Then, they will move it to the Test Path room to realign its lights and wheels, as well as testing its newly installed brakes.
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 test run their very own Emden Lotz.
