Cooling/Electrical System – FanBelts
Checking the fan belt is an easy task. By pushing on the fan belt you can ascertain if the tension is firm or loose. Also, first thing in the morning, by revving the engine, you may notice a high pitched screech. This indicates the fan belt is loose and needs attention ASAP. A high pitched screech may also self destruct a fan belt particularly if it’s a polyrib belt, that is a later generation type belt. It’s also called a serpentine belt.
