here's my problems. About 8 months ago I picked up a 90 cherokee 4.0L 4 wheel drive 125k miles for $750 (friend of the family kinda deal, been sitting for a bit and wanted to get rid of it. Guy said the electric fan was bad on it. No big deal. Brought it home. Did a quick fix to the fan and hooked it up to a toggle switch. Next day went and got a 3" lift for it and some 31's on some rims. (Small I know, got it to be the girlfriends rig). Ok so we started heading out to a jeep show. On the way there it over heated like 6 times. No biggie I didn't care. Well I pulled the head and got it milled. They took .015 off of it. So I put it back on. Then did some research on the Renix cooling system. Didnt like what I was seeing so I replaced everything ( One of the perks of working at a shop, get parts cheap lol). Brand new radiator, overflow bottle, water pump, radiator cap, hoses and thermostat ( open cooling system set up from a newer style cherokee.). So I got it all together. Started driving it around and the gauge is reading hot again and it was pushing coolant through the radiator cap. I figured it was a bad motor and didn't wanna waste my time trying to figure it out. So I had a parts jeep with a perfectly good motor in it around the same miles. So I replaced the motor with the new known good one. Start it up. Running good for about an hour than started doing the same thing ( Pushing it through the cap). Noticed the heater control valve was sticking. So instead of replacing it. I just removed it and looped the hoses together for it to run straight through without restrictions. Still doing the same damn thing Next I removed the thermostat. Same thing. I'm kinda lost here. I don't mind doing the work but the repetition part is anoyying. The girlfriend loves the car she doesn't want to get rid of it so I'm trying to get it working.
Any suggestions will be appreciated!!
**NOTE**
YES THE WATER PUMP IS THE RIGHT ONE AND THE FINS ARE THE RIGHT DIRECTION. I TRIPLE CHECKED.
THANK YOU I ADVANCE
