Here is the new fan installed. This is off a 93 4.0 looks small but I think it will do the job. To bad now its cool out and in the 60s and the hood it off it but it did seem to run at 210 in the driveway. I let it run a for a while. Ill have to put the hood back on and take it for a drive to see what happens.

Not sure where you are at with your project, but I have a solution for you.
Knock out the freeze plugs on the side of the block. You can then run pieces of stiff wire up into the water jackets to see if you have any blockage. I have seen factory plugs pulled and behind them nothing but rust/mud/stuff.

Thanx but I think the new fan will fix things. Only time will tell. Of course now it cool out so it probably wont overheat until next summer.

If I am not mistaken your fan shroud could be the cause of your overheating problems.That isn't a fan shroud for a YJ. I think it is for a 4cyl Cherokee or Briarwood and that would make it overheat for sure

EDIT:

See if you can find this part number on it 5300 0015. If so then it is for a cherokee.
Part number should be 5200 4214-1. And the ahroud completely encases the fan so you can not see it from above like your can be in your picture.

Well this shroud came right from the dlr. They looked it up and said that was the one I needed. The 4cyl is bigger and encases the fan totaly. I have the 6cyl.

I think its the new 7 blade fan making it look bigger. Not sure why but the 5 blade fan blades I had on there before were bigger. Not sure if that will hurt things or not. The yard that I got this from said it was off a 93 6cyl wrangler.

Not sure why Jeep would use a 5 and a 7 blade fan on these things. It does seem to be pulling more air and pulling it the right way. I guess only time will tell.

OK update on tis. I let the Jeep run after I swapped out H2O for coolant/H2O mix.

It took longer but it did get up to the 220 mark sitting at idle and no hood and 75deg out side. I parked it after that so i dont know if it would go higher or not at this time.

Do I still have an issue. I thought it would stay at 210 and not go higher.

Also there was no heat now. It was luke warm at best. Could the tstat have gone bad even though it was a new one. ????

sounds like your heater core is clogged.

I have run into this problem before on another vahicle and the way I diagnosed it was to pull the radiator hoses completely off,put your garden hose on the lower hose(this will insure a constant supply of WARM water Don't use cold as you will run the risk of cracking the block) let it run for a while and see what happens. If it overheats then you have a blockage somewhere. If not then it can be a couple things, Poor circulation -you will be pressuring the water through and basically bypassing the water pump. Or the radiator is not working properly but after all the things you have done I would bet it is not the radiator
Try this it is FREE and may lead you in the right direction Good Luck

I have to agree with laybackman, the one on the picture isn't a fan shroud for a 4.0L. The space between tip of blade and shroud should be less and the shroud doesn't look like an original one. Go by the jeep dealer with the partnumber laybackman supplied and get a good one. You'll see the difference immidiately.

I know mine would never take the lower picture.

To late to call the dlr now. But I did get the one I have from them. They said it was the one for a 6cyl wrangler. I could not find a part number on it. Well not with out pulling it. Were is the part number located and Ill post that.

The good news is i got the hood and windshield back on. and took it the same 4 mile loop and it did not over heat. Stayed around 210. But when I stopped for a bit it would climb to 220.

So I am making progress.

My shroud on my 91 is stock and looks identical to yours. My fan blades (which are stock, also) are larger than yours leaving only 1 inch between tip of fan and the shroud. I took some pics but am having trouble sizing them. I'll do my best to get them up tonight.

I work on a lot of 4 bangers. They use that big shroud. I am certain your shroud is Ok. Fan does not look right.

The fan is off a 93 wrangler I was told by the salvage yard. Mine use to have a 5 blade this is a 7 blade. if you got pictures post them to photobucket.com.
I have been searching for someone with a 6 and the right fan to post pictures.

Thanx

Here are the pics. It is a five blad but notice it is larger. I have owned this jeep since new. Never changed fan or clutch assembly so I know it is right.
