Re: Why does engine overheat while sitting at idle ?

The variable mechanical/electric fan clutch, and added heat from the AC condenser can contribute to the overheating.

It is also important to have a fan shroud that is intact, as well as a clean condenser and radiator. Debris in the front and between the condenser and radiator can impede cooling.

Check the fuse and relay for the fan clutch first.
