Ok, I had a guy help me replace the head gasket on my 1990 Cherokee. We took the head it had it pressure tested and magnafluxed- all good. We finally finished yesterday and it is still overheating. It only idles for about 5-8 minutes before it passes 210 and keeps climbing until I shut it off around 250. No water in the oil or anything.
I've replaced the water pump and the thermostat (which there wasnt a t-stat in there when I opened it up. Previous owner must have removed it) and now have done the head work. What else could it be? I have no radiator cap- it's the pressurized system with the fill tank.
Also, even when it is running, that top hose feels empty, like no coolant is passing through it. Does that sound like my radiator might be bad? Or the heater control valve? Bad water pump?
If it is the radiator, I've seen some on here suggest going to the open system instead of the closed system I have now. How big of a deal it that to change?
