After battling with my closed cooling sytem for over the last year I can tell you that once the cap or the bottle cracks you will start overheating. If you are going to replace the radiator the plastic tank ones work fine, I just installed one from Oreilly's, Just make sure you burp it good or...

Ok so I burped the system 2 more times and guess what? A ton more air was in there. Now my Jeep runs a cool 195. The thermostat opens and it drops to about 150ish and then rises back to 195ish and the cycle begins again, just like it is supposed to. And here I was talking about changing head...

Ok just got a wild hair up my butt and decided to go out and burp it one more time. I jacked the rear end up as high as I could and pulled the coolant temp sending unit at the back of the head, it took about 2 to 3 minute before any coolant ran out. Talk about a major air bubble. Then I jacked...

Well, I just figured it wouldn't be a bad idea since the exhaust manifold looks tore up anyways. maybe I could try runing a few beads on the exhaust manifold and wrap it real good and see if that helps. I think I might try the hood spacer idea on the back of the hood for a few days and see...

Ok, looked at my reciept and I have the right one listed for my jeep. And as I recall I checked the impellers when I installed it, they were the same. I did just notice a crack on my exhaust manifold. I might just throw a head gasket and a new exhaust manifold at this thing, it is really the...

Well which one goes on what motor? And how the heck do I find out what I have and what I need? I still have the reciept for the waterpump that I have installed, I will check the waterpump against Napa's website and see which one I have on there right now.

Everything in my cooling system has been replaced. EVERTHING is less than 6 months old.

So todays results after bleeding the system some more last night I am still running 230 on the big hill coming home. I think tonight I am just going to pour some gas on this thing and burn it. This problem never seems to go away.

I have an open system just like a 91 and newer, I did the conversion.

Okay, last night I jacked the drivers side front of my jeep up as high as I could get it and took the cap off while it was running and wiggled and squeezed every hose I could and got a bunch of air out. I knew there was still air in there. I will report my results after work tonight and see if...

Mine seems to have an EGR, it is an 89. I need to look into this.

Hey vanimal, those fail safe thermostats are no good. After a certain temp they just stay open.

Ok thanks for the infor Ecomike and lloking forward to hearing how everything goes Vanimal. I would like to hear your results. It sounds like we are having siilar problems so it is nice to have some comparison to get the gears turning. I got to messing around some more last night and started...

The actual temp of the sensor on the back of the head is 200

ok went out and checked it again with the IR thermometer most of the head except for the area right above where the exhaust ports are at stay right around 180 right above the exhaust ports it is closer to 250. So what is a good temp for a catalytic that is not plugged.
