Changed the thermostat, checked the idler pulley and the raw water impeller. I thought I had the impeller in backwards at first and changed it around, but that didn’t make a difference either way to be honest. How would you know if the heat exchanger is the problem? Should this hose be hot? It was cold and my engine temp was climbing from 165 to 171 at idle speed on the fake a lake in the driveway. It also seemed like water wasn’t coming out of my exhaust like normal after idling for about 3-4 minutes so I killed the engine. It started out spewing water like always. Any thoughts?
