I seem to be having a overheating problem.(1989 cherokee,4.0l, auto trans) The truck runs pretty cool most of the time except when climbing hills and summits. It goes from normal too hot in a matter of minutes.If I'm crawling in 4wd I can climb all day long without even getting close too hot. I have replaced the fan clutch thermostat and all hoses,cleaned dirt and mud from my condensor and radiator,installed a 185 thermostat,added a bottle of towcool to the coolant to no avail. I do not trust that pressurized coolant tank setup but it seems to work. At this point I'm thinking of installing a newer style rad with the normal resevoir and a waterpump, good idea? Any help would be geatly appreciated! (Big fishing trip in a few days to a mountain lake.)
