They said it was a Part master reboxed it was Stant in the box. But not super stant..

I guess I'll go with the 180 first.
Stay at 195* Don't bother with the 180

I figured it's about time I entered this thread. I'm no cooling system expert, but I played this same "ball game" with my jeep for the last 6 or so months. Rusty up there can vouch for that.

So judging by all the posts, and all the things you have tried to do, I have what I hope is an answer to your problem. So you have an IR thermo? Perfect. Run the engine till it gets pretty warm and start diagnosing. Measure as many different spots of the block as you can and note ANY hotspots. Measure the exhaust manifold tubes for each cylinder and see if one is hotter/cooler than the other. Also, are you still going through coolant?? Have you retested the block for combustion gasses in the coolant?

If you had the head redone, and its been tested for leaks and passed, then one of the above methods should dhow something. There is probably a good chance that there is a clog in your block. There is one way to find out for sure but it really sucks. And thats to pull the motor and knock out the freeze plugs. That will allow you total access to see if there is blockage in the water jacket. My case ended up costing me a new motor. Hope this helps, Brian

Thanx for the ideas. WOW new motor. I just dumped $1200 into this heep engine. For a few more I could have had a v8

So there is no way to unplug a block?


What was wrong with yours that you needed a new engine?

I got it from a local radiator shop that had been around for about 30 years. I like to support local businesses when I can.
And I would stick with the 195* t-stat as well.

I saw this on an XJ. We ended up swapping in a newer style coolant res. For some reason the old one would allow enough pressure to keep it cooled down.

Do you have AC? If not, I am thinking it, as others have mentioned, is a water pump issue. Your old pump should have had an R stamped in the casting. As others have said. I think you have the wrong water pump. Mine is a 91 with no AC. It requires a reverse water pump. I hope this helps.

I hate to see you throwing money at it but look at the bright side. You have a lot of spare parts and it is a Jeep thing. You will need all that stuff eventually.

I have AC and I don't have the original pump any more. I keep calling the part places they they tell me there is only one pump listed for my engine.

I am thinking that too but none here in SFL seem to know there is another pump.

If anyone knows the part numbers may be I can ref that at ths parts store.

From what i can find out its 91 that has the 2 pumps not a 92. 92 had a reverse flow pump and that all that will bolt up to it.

This is what I have on mine. Your year calls for the same thing. Question? Do you have a serpantine belt?

did you check to see if the coolant was flowing?

try running it without the t-stat in. If it still over heats then the serp belt is routed wrong and spinning the pump backwards or you botched the head job.

You don't have to buy the Flow Kooler. I am pretty certain you need a reverse flowing water pump. And stop stressing that engine.

Have you checked the coolant for combustion gases??? A simple test could tell you if you have a leaking head gasket or a possable cracked head. Most shops use a dye that is blue and if it turns green you have combustion gases in the coolant. Also have you tried to burp any air pockets out of the coolant system?
