This article is about car parts and what they do in real life. For the article about bolt sizes, see Bolt sizes.

Below is a list of car parts used in the game and what their real life purpose is. Some cosmetic parts are not included, such as Fender flares and Dash covers.

Part Purpose
Subframe Structural component bolted to the body of the car that bears the powertrain (the combination of engine, transmission and drive wheels).
Wishbone A part used on some front suspensions to locate the wheel. It bolts to the subframe.
Spindle Suspension part carrying the wheel hub.
Disc Brake A type of brake rotor that uses disc rotors that rub against a brake pad to stop the vehicle
Halfshaft Part used on front wheel drive suspensions that transmits power from the differential to the front wheels
Steering Rack A type of steering system operated by a pinion gear that pushes the steering rack from either left or right when the steering wheel is turned
Steering Rod (AKA tie rods) A tie in a steering gear of a vehicle's suspension system
Strut A coil spring enclosed in a strut that dampens and smooths out the ride of the vehicle
Wheels Moves the vehicle. On a front wheel drive vehicle like the Satsuma, the front wheels receive power from the drivetrain while the rear wheels are unpowered,
Steering Column A shaft connecting to the suspension allowing the driver to turn the vehicle using the steering wheel
Trail Arm A type of suspension arm connected between the axle and a pivot point
Coil Springs Springs used to dampen and smooth the ride of the vehicle
Shock Absorber A vapor gas filled tube that dampens shock impulses, helping to smooth out the ride of the vehicle
Drum Brakes A type of brake that has internal mechanic parts that push against an asbestos based friction pad to stop the vehicle
Engine Block A part either made out of cast iron or aluminum that holds the pistons and other internal engine components.
Crankshaft A shaft to which the pistons are attached which transforms the reciprocating (up and down) motion of the pistons into rotational motion.
Main Bearing A bearing that hold the crankshaft to the block, allowing it to rotate. The Satsuma's engine uses three bearings.
Piston A primary component of the engine. In a four-stroke engine like the Satsuma's, the piston first moves downward, taking in an air/fuel mixture (intake). In the second stroke, the piston moves up and compresses the mixture against a spark plug (compression). The plug ignites the mixture, which pushes the piston back down, driving the crankshaft (combustion/power). In the final stroke, the piston then moves up again, forcing exhaust fumes out of the combustion chamber (exhaust).
Head Gasket A gasket seal preventing fuel or air from leaking from around the block.
Cylinder Head The part where the valves rest and the spark plugs screw into, also known as the combustion chamber.
Headers Also known as the exhaust manifold, is the part where the burned fuel and air mixture gets released into the exhaust pipe to exit from the muffler out of the vehicle.
Carburator A mechanically operated part that blends fuel and air to be pushed into the combustion chamber to be ignited and released through the intake valve.
Rocker Shaft Also known as the Valve Train, it is a series of intake and exhaust valves that open and close to let the fuel/air mixture in and out of the cylinders.
Rocker Cover A plastic, aluminum, or metal cover that covers the Rocker Shaft.
Camshaft A shaft with cams attached to it that rotates, controlling the opening and closing of the valves on the Rocker Shaft / Valve Train.
Camshaft Gear The gear that drives the camshaft. It is attached to the crankshaft by the Timing Chain.
Timing Chain A chain that is specially timed to move the camshaft to open and close the intake and exhaust valves at certain times.
Timing Cover A cover that encloses the Camshaft Gear and Timing Chain.
Water Pump A pump that circulates coolant through the engine once the engine is running, dissipating heat in the engine.
Water Pump Pulley A pulley that operates the water pump.
Crankshaft Pulley A pulley that drives the Crankshaft and the Alternator.
Alternator An electrical power generator for a vehicle's electrical system that charges the battery when the engine is running.
Fan Belt A belt used to drive multiple pulleys on a vehicle's engine.
Starter A part used to rotate parts in an engine when it is first turned on, allowing the engine to complete a combustion cycle, which then enables it to run on its own power.
Flywheel A rotating part used on vehicles with manual transmissions that stores rotational energy, providing constant energy when the vehicle is running and smoothing out the rotation of the crankshaft.
Clutch Cover Plate A plate on a manual transmission's clutch that clamps the clutch to the Flywheel.
Clutch Pressure Plate A part on a manual transmission's clutch system that releases constant pressure.
Clutch Disc A disc used on a disc type clutch where friction to power the clutch lies between two plates, the cover plate and the pressure plate.
Oil Pan The bottom of an engine where the oil falls into and recirculates to the top through the bottom of the engine, lubricating the entire engine. Once the vehicle is off, the oil drops to the oil pan and remains there until the engine is ignited once more.
Gearbox (AKA a Transmission) The component that transmits power to the vehicle's drive wheels. In this case, the Gearbox/Transmission on the Satsuma transmits power to the front wheels, since the Satsuma is a FWD (Front Wheel Drive) vehicle.
Drive Gear A gear delivering torque to drive the wheels in the vehicle's final gear.
Spark Plug A part used to ignite the fuel and air mixture in an engine.
Fuel Pump A pump used to pump/feed fuel from the fuel tank to the engine.
Distributor A mechanically-timed rotating shaft that provides electricity to the spark plugs.
Battery A battery that supplies electrical energy to a vehicle.
Electrics Electrical wires providing power to electrical components in the vehicle.
Fuel Strainer (AKA a Fuel Filter) A filter that removes dirt particulates from the vehicle's fuel.
Radiator A part, usually made of brass or aluminum, that circulates coolant through the vehicle's engine and transfers waste heat away from the engine.
Radiator Hoses Hoses leading from the engine to the radiator and back.
Oil Filter A filter where dirt particulates in the oil are removed from it, and kept in the filter so dirt won't flow through the engine.
Clutch Master Cylinder A pump that pumps brake/clutch fluid to the clutch.
Brake Master Cylinder A pump that pumps brake/clutch fluid to all four brakes through brake lines.
Clutch Lining Lines through which brake/clutch fluid travels to the clutch.
Brake Lining Lines through which brake/clutch fluid travels to the brakes.
Fuel Tank A tank where fuel is stored for the engine.
Gear Linkage Parts that link the gear stick to the transmission to change gears.
Gear Stick A stick shift used to change gears on a vehicle.
Handbrake A special brake used to prevent the vehicle from rolling when parked on hills. Also called a parking brake.
Exhaust Pipe The pipe connected to the headers where the burned fuel/air mixture from the engine is released through.
Exhaust Muffler A part on the end of the exhaust pipe that "muffles" the exhaust noise, quieting engine noise.
Fuel Tank Pipe A tube that allows the driver to fill the Fuel Tank with fuel.
Dashboard An interior component where gauges and the radio are displayed.
Steering Wheel A part connected to the Steering Column that is used to steer the vehicle.
