A Nissan 240SX radiator is a fairly flimsy piece of equipment. It is constructed out of a hard plastic framework with an aluminum core. The core is comprised of a series of aluminum tubes that carry the hot coolant.

Heat is transferred through conduction from the fluid into the metal of the tubes. The heat is then transferred to the thousands of thin aluminum fins that are attached to the tubing. Airflow, either from the forward motion of the car or from the auxiliary cooling fan, dissipates the heat from the fins and into the atmosphere.

The Nissan 240SX’s radiator is no more flimsy than that of any other manufacturer. They must be made out of very light and thin materials to allow the heat to move quickly from one area to another within the system. Because of the delicacy of the design, radiators are prone to damage. If the coolant is not changed regularly (at least every two years), clogs and blockages can develop within the system and impede the radiator’s function. The thin metal is easily punctured, and the development of leaks, no matter now small, is a dangerous symptom of radiator failure. Rocks, sticks, and other debris can strike the fins, bending or breaking them. While a few bent fins is unlikely to cause a significant drop off in the radiator’s performance, significant areas of damage are a pretty clear sign that the life of that radiator is about to come to an end. While Nissan 240SX radiators can be repaired, they can be replaced for almost the same cost, and depending on your source, sometimes less.You can order a replacement Nissan 240SX radiator from our convenient online catalog and know that you are getting a genuine Nissan fit at a great discount.
