Thumbs up Bought me a 2003 Monte!

Like the car. Great potential for solid transportation.
Fixed the issues needing repair for emissions & state inspection. That's done. Now on to sloving this mystery of its over heating engine. Fan works. AC works. Fuses & relays all good. No leaks. Plenty of coolant. Brand new water pump. Belts snug spinning fine. Radiator in perfect condition & recently flushed. Heat pump & blower works. All hoses, clamps, elbows & conections check out. Whats my next move?

New thermostat? 3.8? cooling system bled properly? Fan(s) work but do they come on when they should?

Welcome to the forums. Double check you don't have air in the cool system by opening bleeder screw on top of the thermostat. Other possibility is a bad head gaskets. Good luck
