670x Posted April 17, 2010 Share Posted April 17, 2010 I just fought this on my 88. I replaced the thermostat, flushed the radiator and dug all the bugs out. I replaced the bottle and cap as it would boil over, none of this worked. I finally went to Advance and bought a replacement radiator for 99 bucks. Problem solved, I guess after 240k miles I was due. Then that one started to leak but they had a lifetime warranty so I did it again no problems thus far. I wished I had done this earlier. Link to comment Share on other sites More sharing options...
pilotblake Posted April 18, 2010 Share Posted April 18, 2010 I have a 00 4.7v8 grand cherokee that I fought overheating issues after taking it in to the shop for some work. Turns out somehow when they flushed the system they clogged up the radiator. Long story short everything in the cooling system was replaced before I ended up putting in a new radiator. It turned out to be a plugged radiator. Link to comment Share on other sites More sharing options...

Oizarod115 Posted April 19, 2010 Share Posted April 19, 2010 its possible, any restriction of air on that half-sized radiator we've got will cause problems. Link to comment Share on other sites More sharing options...
