This concerns a 91 comanche. Inline 6. Automatic with about 150, 000 miles. 4.0 liter. Same a a cherokee.
yesterday I stalled from overheating and the overflow of the overflow resevoir was overflowing. I topped off the water and shortly their after, 5 minutes maybe, same thing.
the upper rad hose is hot, so I thought not the thermostat, but when I pinch it, I do not feel a surge of pressure upon release. So I replaced the water pump. Still the same. And still no surge when I pinch the hose.
the radiator was replaces about 3-4 years ago, so was the water pump. Other than the new water pump installed this morning. New rad cap about 2 weeks ago and a new transmission filter about a month ago.
all help appreciated
have the same problem?
