Belt: Your cars cooling system uses an engine belt to drive the cooling blower fan. Some cars have an additional electric motor to force air over the auto radiators core.

Blower/Blower Motor:the fan assembly that forces air across the cooling core of the car radiator.

Coolant:mixture of anti-freeze and water used to cool automobile engine.

Coolant Overflow Tank: When a car gets hot, the coolant expands and partially fills the coolant overflow tank. This is normal.

Fan: Same thing as Blower.

Heater Core: uses hot coolant coming from the engine to heat air for your car’s heater.

Hoses: All car radiators use several hoses to pass the coolant to and from the engine. They are connected to the auto radiator and engine with hose clamps.

Oil Cooler: A secondary cooling system used in cars with automatic transmissions. It cools the oil from the automatic transmission.

Auto Radiators: The grid of specially shaped metal tubes (cores) behind the grill of a car. Hot coolant passes through these cores and is cooled by the air passing over them.

Radiator Cap: The pressure sensitive radiator cap on the top of the radiator. It increases the pressure in the cooling system, allowing more efficient cooling. The radiator cap is also designed to expel excess pressure caused from the coolant becoming too hot or boiling. This prevents damage to the cooling system.

Thermostat: regulates the flow of coolant through the engine. It only opens when the engine gets hot enough, allowing your engine to heat up quickly. This helps car warm up properly in the winter, when there is a extreme difference in temperatures between the outside are and the engine temp.

Transmission Oil Cooler: Same as the Cooler.

Water Pump: pump that forces coolant through the cooling system.
