My 90 Jeep Cherokee Pioneer overheats. We have changed the resivoir bottle, removed the thermostat, and flushed the system. The water pump is working and everything seems fine untill it gets hot. It dosn't take long. Do you have any jnfo on this model having this problem? Please help if you can.

Hi , I have 2 jeep cherokees, bothwith the same overheating problem. One the head gasket has gone I am replacing it now. but when I removed the heads. I found that there were holes in nearly all the 20mm core plugs and this is where I am losing most of my water causing me to overheat. the other was the head gasket , .. Hope this helps. Tony
