Lately my truck has been running to hot while idling. As long as I am driving it is fine, but if I have to sit at a stop light for a while the temp will rise fairly quickly. I was thinking it might be the fan clutch, does that sound possible? Should you be able to grab ahold of the fan and move it relativly easy, becuase mine is really hard to turn.
Also, an explanation of what a fan clutch does would also be appreciated ( I want to make sure I have it correct).
