Internal and External Parts make up the essential components of a vehicle's cooling system. Internal parts, such as radiators and oil coolers help manage engine temperatures by transferring heat away from the engine. External parts, such as fans, pressure plates and thermostats help increase air flow and maintain the ideal operating temperatures.

The Internal and External Parts of a cooling system offer a number of benefits.
