Radiator Parts

The radiator plays an integral role in the overall functioning of your vehicle. Your car's engine produces substantial amounts of heat, and the coolant keeps the heat at a manageable level. Without proper heat management, it can result in overheating, which can severely damage your engine.

The water pump pushes the coolant through dedicated passages all around the block and cylinder head. The hot coolant then exits the engine and is pushed into the radiator, cooled through convection. Many radiators also feature fans that allow the air to pass through the radiator even when the vehicle is stopped.

Your car's coolant system is generally designed to last a long time; however, many components fail with age. For many enthusiasts, upgrading the cooling system with aftermarket parts is an absolute must. As you increase power, you also increase heat output, easily overwhelm the stock cooling system.

The thermostat controls the temperature by regulating water flow throughout the cooling system. If the thermostat fails, it can get stuck open, close, or partially open. This can result in excessive cooling in cold weather or lack of cooling in hot weather.

The serpentine belt typically drives the water pump; however, some vehicles use an electric water pump. The pump uses an impeller to push coolant through the engine and radiator. Unfortunately, the water pump can lock up with age and will no longer cycle coolant through the system.

The heater core is mechanically and physically very similar to the radiator, albeit smaller, and it serves a different purpose. The heater core even features a comparable system of tiny gauge tubes that generate hot air for the heating system. Once bits and pieces split away from the radiator's pipes, they eventually get clogged in the heater core's tubes.

Just because it creates a "snug" fit, it doesn't necessarily mean that it does its job. The only real way to test it is to mimic a closed and functioning cooling system's effects. You can do this by performing a compression test on the cap of the radiator. The radiator cap is attached to a device that applies a specific amount of pressure, after which you can monitor the device to see if the pressure drops. The radiator cap should be able to hold the amount of pressure to which it is rated.
