I was poking around somewhere else and I noticed you stated you took the AC out. Is that correct?

desieling?

Does it desiel at all or want to keep runing whhen you shut it off? It there is any hint of this it could be the timing causing it to over heat.
I had a straight 6 that was out of time and ran hot. I changed the radiator, carb, plugs,water pump and on and on. I got the timing right about 4 years later when I read the right manual it never got hot after that.

Ditch the compressor. Get the right no/ac serp then let me know.

Why I don't think that is hurting it. I was going to take it off at some point.

Do I just get a belt for a Jeep with no AC ? Pepboys is stupid on some of this stuff.

It a parasitic drag you don't need. Just tell em 92 4.0 No AC.

Should take you all of 15 minutes if you have the condenser already removed.

Well I have taken the lat 2 days off from wroking on it. Need the time away from the heep as it were.

I plan on back flushing the block this weekend if time allows.

Super Chevy is in town this weekend my Vette may need to go there for some execrise on the track.

By the way.... You have to put in an AC cancelling kit if you remove the compressor. Taking out the compressor reroutes the belt and I believe it will turn some stuff backwards if you do it incorrectly.

On another note, to clear up the clutch fan thing, your fan uses viscous fluid, which means it thickens up when it heats up as the fan spins. Jeep fans don't "un-engage" at high speeds. Basically the fan should almost free spin when it's cold, and be much harder to spin after it hot from running for a few minutes. When you go to spin it after you shut the jeep off, it should only turn about 1/2 a turn on it's own when you spin it.

Haven't you already flushed the block once? Did you actually run a coolant system cleaner in it?

Did you shoot multiple points on the block for hotpsots?

Well my clutch fan has a spring it in not a fluid. So nto sure what you are talking about.

When I shut it down the fan stops right away and is "tight" to turn so I am assuming it is good. When it is cool it moves much more freely.

I have never used any "cleaner " in the block Just forward flushed it. Someone recomended doing a back flush on it. So I was going to try that.

Most are viscous.

But anyways, try the backflush and try running prestones coolant system flush liquid. It helps to break down some of the crap in the block and head.

I would recommend going to a Minute-Lube type place and seeing if they do forward/back flushes.

Tell them you're having some headaches with overheating and ask them to flush the c$#p out of it in both directions until they see some gunk come out.
