Your radiator is an integral part of your car or truck's cooling system. It allows the immense heat generated by your engine to be dissipated more easily into the air, keeping the engine running at its optimal temperature. A problem with your radiator can be a big problem for the overall functioning of your car, truck, or SUV. Although the operating principles for an automotive radiator are fairly straightforward, there are a lot of fine details you may want to know if you're having any trouble with your radiator.
Before we get to anything more complicated, let's start with the basics. The radiator is at the front of your car or truck's engine bay, behind the grille. It attaches to a large metal frame called the radiator core support. This, in turn, is connected to the frame of the vehicle. The radiator is usually attached by a pair of brackets at the top, and rests on a set of rubber bushings at the bottom.
