Your GMC K3500 radiator is the essential core component of your vehicle’s cooling system. It is easy to locate your radiator when you open up your hood--it is the large, somewhat thin rectangular component situated near the front of your engine bay, between your front grille and your auxiliary fan. The K3500 radiator is composed of a series of tubes and passages designed to hold a lot of liquid, between two “walls” of horizontal or vertical fins.

Two radiator hoses, an upper and a lower, lead into and out of your radiator to facilitate heat exchange for the coolant that runs through your engine. When heated coolant enters your GMC K3500 radiator, it is spread out through the tubes and passages, which increases the fluid’s surface area.

In addition, moving air coming through your front grille while you are driving, or from your auxiliary fan when your vehicle is idling, assists in the cooling process. Problems with your K3500 radiator, such as leaks or blockage, will quickly cause your engine to overheat, which can cause serious and sometimes permanent damage. Regularly cleaning and flushing your GMC K3500 radiator according to the manufacturer’s recommendations is an essential step in ensuring that your radiator enjoys a good, long life. You should also check your radiator hoses and your coolant reservoir regularly for leaks. Eventually, however, your K3500 radiator will be subjected to rust and corrosion through normal use, and may develop leaks.When this happens, look no further than our extensive online catalogue for a high-quality, inexpensive replacement radiator, and get your new component shipped right to your door.
