1st time poster. I have a 1990 (closed cooling system) AT, 4wd, 31"tires, 140,000 miles, fresh fluids through out.
It was running "fine" but at 240 deg. I researched and found that others said that they run hot and was fine. One day it boiled over ( under the cap) going up a hill. I stopped, let it cool, topped it off drove home stayed at 190.
I then flushed the system (10min flush). Replaced all hoses, belt, T-stat/housing, fan clutch. Jacked up the back, removed the temp sensor filled with coolant closed everything up and took it for a drive. It ran at 190 deg on the freeway, up hills, and around town until I shut it off. After it was shut off it start boiling over from under the cap.
So i bought a Dorman replacement. And that is where I am now. The new bottle still leaks and I am over heating going up a hill.
So I guess my two problems are bottle not holding pressure and overheating going up hill.
As far as the bottle goes is it normal for the overflow to fill to the top after the XJ is shut off?
And the over heating, I think is a problem with the electric fan. It will come on with the AC but only randomly comes on if the temp goes above 210.
Any input is greatly appreciated.
