I took the Cherokee out Sat. to do the Moody Hill/Ballard Rd. run with the group. It was about 55 miles to the meeting spot, Jeep ran great on the Hwy and had no issues. Actually did really well on MPG at 21 MPG. This was my maiden voyage with the XJ. After we left the meeting place and got in the hills, the Temp started to increase. I let it cool down when we stopped to air down, but when going up to the trail head, it started to heat up again. I decided not to proceed and turned around. My question is, is it worth changing out to an open system? My pressure tank seems to hold pressure, but the Elec. fan (I found) is not switching on. I am going to replace the elec. fan/switch, remove the AC condenser (AC pump converted to air pump), and do a flush the system (possible thermostat). I am wondering if I should change it to an open system, since I am going to have it apart, or is it not worth the effort or money? I am hoping the elec. fan will cure the issue, but I am wondering if I have something else going on.
I know this group has a lot of XJ's , so looking for insite on how to cure the problem.
Thank you
