Do you know basic car anatomy?
Radiators help absorb heat from the coolant and regulate the engine’s temperature. A mix of coolant and water is released from the radiator, which then absorbs the engine’s heat.
The transmission contains gears that transfer power from the engine to the wheels. As the speed of a vehicle increases, the gears must be shifted to accommodate.
Think of the chassis as the foundation. Not only is the chassis where the engine, brakes, axle and other major components are bolted and protected, it also helps reduce vibration and noise in the vehicle.
