Coolant Doesn't Seem To Be Cycling Properly

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.

With a 20+ year old engine, it is very possible that the vanes of the water pump have been eroded to the point where the water pump just isn’t pumping.

Are you getting plenty of heat into the cabin?
