So here's the issue. Going up a forest road near Carbonado in the Mount Rainier National Park yesterday, my temp gage kept climbing to 230 deg. I finally had to turn around a head down the hill to prevent overheating my rig.
Now before all the suggestions start flying in telling me to replace cooling system components. Let me give you the 411 on my rig.
1993 Cherokee sport. 4.0L automatic trans with 4:10 gears. 212k miles on it. I have owned it for 6 years. Over the last year or so it started running hot while towing my dirt bike over the pass or up steep grades. I take good care of my rig with regular fluid changes and flushes.
Recently I have replaced many parts on it, including the Radiator, waterpump, theromstat, cooling fans.
So my questions are. What coul be causing the higher running temp only on hills, and what can I do to fix it?
Thanks

- Mr Gasket 180 deg high flow thermostat
- new hoses
- 3 thermostatically controlled electric fans with manual over ride at 1050 cfm.
