1990 xj, 4l.
5 inch lift on 31s.
My jeep started overheating recently, this was after only being driven once or twice a month through the spring.
It first happened climbing a mountain here in BC. Then after it overheated there i noticed it would hit the red when on the highway at around 100 kmh. When driving around down or sitting at a light it doesnt seem to go over normal temp (~100 c)
I have..
replaced the thermostat
checked all hoses
burped twice
flushed till crystal clear, heater core too
added electric aux fan from newer jeep and put it on toggle, didnt do much.
radiators fins are clean and clear
new pressure bottle and cap.
Did a compression test to make sure no blown head gasket, everything between 130-150 psi,
no coolant in oil
no oil in coolant
im about to replace fan clutch but i figure highway speeds should work just as good so it "shouldnt" be the fan clutch.
One thing i did notice though, when driving, if i stomp on it, once the rpms get to around 3k it seems to have a serge of power! not sure if its related or if thats a whole other issue.
I need ideas... Thanks in advance!
