We ran the car for a few days before going ahead with the Hypertech install, just so we could see how the cooling system worked before and after the new radiator install. It was now time to install the fan temperature switch. This little switch is located in a hard-to-reach location on this Third-Generation Camaro. In other vehicles it may be easily accessible. The sensor is located on the passenger side of the engine, just below the heat shield connected to the block. Not the easiest spot in the world, but we still managed.
