The battery supplies the power necessary to start the engine when the ignition switch is is turned on.

The primary component of the lubrication system is engine oil. Engines require oil blends with different thickness (viscosity) and additives depending on their operating conditions. Viscosity is rated using the format XW-XX with the number preceding the W (winter) rating the oil’s viscosity at 0 ℉ (-17.8 ℃) and the XX indicating viscosity at 100 ℃.

Spark plugs receive current from the distributor and use it to spark combustion in the combustion chamber of a cylinder.

Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.
