I know it’s not MJ tech but I want eyes on this. Since this is my first 6cyl I’m now encountering issues with staying cool. At first I thought it was the thermostat. I took the old one out, tested it, it opened way later than it should have.
New one in. No change.
Flushed the block, manifold and core. No change. Yes it’s been burped.
Replaced the radiator cap cause the rubber was basically a rock. Some change but not enough.
Fan clutch locks up when it should and feels normal when engine is off.
I swear I cleaned the fins out but maybe I didn’t.
Water pump is new. Replaced it when I did the head gasket. And it does rotate the right direction.
headgasket has been replaced.
Any ideas? Did my headgasket blow again? It slowly creeps up and takes about 10 miles of driving before I’m damn near out of the green on the gauge.
