The Nissan 300ZX radiator, like all automobile radiators, is designed to keep the engine cool. The cooling system begins at the block, where a water jacket built into the engine block absorbs the heat of combustion. The now hot coolant is drawn out of the engine by the water pump, which is a small impellor.

The pump drives the coolant to the thermostat, which closes or opens based upon the temperature of the coolant. When the coolant is cool, the thermostat remains closed, and returns the coolant to the engine.

When it is open, the coolant moves to the radiator, where it dissipates its heat into the atmosphere. The now cooled coolant returns to the engine where the process begins again. The radiator itself is the most important element of the cooling system. The Nissan 300ZX radiator is constructed of al aluminum framework, upon which are mounted a series of aluminum tubes. The coolant runs within these tubes. Attached to the tubes are thousands of tiny, paper thin radiating aluminum fins. The heat from the coolant is absorbed into the skin of the aluminum tubes, and from there, it is conducted into the fins, which quickly lose it as it disperses into the cooler surrounding air. Airflow is achieved by the forward motion of the car, or, when it is stopped, the auxiliary cooling fan. The Nissan 300ZX radiator is somewhat delicate, and a properly working radiator is absolutely essential to keeping the engine healthy. A failed radiator can lead to an overheated engine, which can be terminal.If your radiator is damaged, you can order a genuine Nissan 300ZX radiator from our convenient online catalogue and have it shipped directly to your door.
