I have a 1999 Alero that seems to be running hot when it is not in motion. I have replaced my water pump and thermostat. It continues to run hot when I am simply at a red light or in a drive-through. My fans seen to be running just fine. But I don't know what else it could be. Can somebody please help....

Welcome to AF.

Could be several things to cause this.

If the cooling system hasnt been serviced resently it might be time for a cooling system flush and new antifreeze added.

If thats been done, then you could have a bad lower intake gasket(LIM) leak.

AN air pocket trapped in the cooling system can make it run hot also.

hope that helps.
