I have a 93 Jeep Cherokee, I just replaced the thermostat and the radiator cap, it’s not overheating, however the radiator cap isn’t even warming up and the thermostat housing heats up quite a bit.
The hose from the radiator to the thermostat gets very hot, but I don’t feel anything being pumped. The coolant is also being drained from the reservoir, but I see little to none leaking underneath the vehicle. I pop off the radiator cap while it’s in idle and see no movement and the coolant stays cool.
