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 available in the game is the Ribbsan Z530, or in the real life, it is the Nissan 350Z, two-seater sports car that was manufactured by Nissan from 2002 to 2008.
How to Restore a Ribbsan Z530
Players can find, and buy, the Ribbsan Z530 in the Junkyard, the Barn, and the Car Auction. Once they have purchased the said car, 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 remaining fluids such as the brake fluid, the coolant, the power steering fluid, and the windshield washer fluid using the Drain Tool.
Once everything is drained, 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, and to detail its interior.
Then, they will repair the parts that they still need to 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 hands, the parts that cannot be fixed will be replaced with new parts instead, and will be sold for additional Credits and Scraps.
Once they repaired and replaced the parts, they can now start reassembling the whole Ribbsan Z530, starting with its engine, which is a V6 DOHC NSN.
In order to do this on the Engine Stand, according to Blues Garage's YouTube video, they will need the engine block, the crankshaft, the six 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 rocker arms, the exhaust manifolds, the camshaft caps, the engine head covers, the spark plugs, the ignition coils, the intake manifolds, the fuel rails, the fuel filter, and the throttles.
They will also need the timing covers, the alternator, the power steering pump, the cam gears, the timing chains, the water pump, the timing chain shoes, the idler rollers, the crankshaft pulley, the serpentine belt, and the belt tensioner.
Once they finished building the whole engine, they will remove it from the Engine Stand, then they will 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 ECU type A, the ABS pump and module, the fuse box and cover with the new relays and fuses, the radiator with its fans, and the air filter with its base, cover and clips.
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 steering wheel and the seats.
Once they finished reassembling the whole car, they will fill it up with the new batch of oil and other fluids, then 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 lights and the wheels, as well as to test the newly-installed braking system.
Then, they will move it to the Dyno Test room to tune up the gears in the 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 very own Ribbsan Z530.
