In Car Mechanic Simulator 2021, players can restore cars that are available, ranging from classic Americana muscle cars to compact cars to modern sports cars, using more than 4,000 car parts.
These cars can either be from those that are already installed in the game, from the downloadable content (DLC) car packs, or from the Steam Workshop where they can download car mods.
One of the said car mods is the one for the 1999 Dodge Viper, a Second Generation variant of a sports car under Dodge's Viper line. It was produced by the American car manufacturer from 1996 to 2002.
How to Restore the 1999 Dodge Viper
Once they have downloaded its car mod file from the Steam Workshop, and pasted it in the game's folder, they can find, and buy, the 1999 Dodge Viper in the Junkyard and the Barn.
Once they have purchased the car, according to Alex K's YouTube video, they will wash its body and interior in the Car Wash, then they will move it to one of the Car Lifts that are in the Garage.
From there, they will drain whatever oil that is remaining inside its engine using the Oil Drain machine, then they will drain the rest of its fluids remaining in their reservoirs such as the brake fluid, the coolant, the power steering fluid, and the windshield washer fluid using the Drain Tool.
Afterwards, they will disassemble the whole car, and get the parts that they will repair or replace, until what is left on the Car Lift is the body frame, which they need to repair using the Wielding Machine, while they will detail the interior.
Then, they will repair the parts they can still use in the restoration project by placing them on the Repair Table, all of which are in the Workshop. From there, they will play a minigame where they need to hit green tabs in order to fully fix them.
On the other hand, the parts that cannot be repaired will be replaced with new ones instead, and they will be sold for additional Credits and Scraps, which they can use to buy and upgrade said parts. If they bought the car in the Junkyard, they will buy the parts that are missing in the car.
Once they have the repaired and replaced parts, they can start reassembling the whole 1999 Dodge Viper, starting with its engine, which is a V12 DOHC MRC.
To do this on the Engine Stand, they will need the engine block, the crankshaft, the twelve 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 heads, the camshafts, the camshaft caps, the six spark plugs, the engine head covers, the six ignition coils, the four exhaust manifolds, the intake manifold, the fuel rail, the fuel filter, and the two throttles.
They will also need the alternator, the power steering pump, the cam gears, the timing chain shoes, the serpentine belt, the timing covers, the timing chain cover, the water pump and its pulleys, the crankshaft pulley, the idler rollers, the belt tensioner, and the thermostat.
Once they finished building the whole engine, they will remove it from Engine Stand, then they will put it inside the car's engine bay with the help of the Engine Pulley.
Then, they will install its internal parts such as the gearbox, the starter, the reservoirs, the air filters with their bases, covers and clips, the battery, the brake servo, the radiator and its fan, the fuse box and its cover with its new relays and fuses, and the ECU type B.
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 rims and tires, the body kit, the lights, the windshield and other glass panels, and the parts for the interior such as the steering wheel and the seats.
Once they finished reassembling the whole car, they will fill its engine with a new batch of oil, then they will also fill its reservoirs with a new batch of its other fluids. Afterwards, they will paint its body with a color of their choice in the Paint Booth.
Then, they will move it to the Test Path room to realign the newly-installed lights and wheels, as well as to test the newly-installed braking system.
Then, they will move it to the Dyno Test room to tune the gears in its gearbox and to perform a dyno test to check the performance of the newly-built engine. Once they are satisfied with the results, they can test drive their own 1999 Dodge Viper.
