Ive never messed with that one but i would venture to say that either a wire from the sensor to the console is unplugged or the sensor is bad. Google or get a repair manual to find the sensor

Congrats on your purchase. You didn't say what year it was, so I'll leave this for '97-'01: >->http://www.lunghd.com/Tech_Articles/...tification.htm
And this for '94:

RememberTheMallamo

Thank you so much ol"blue! It's a '93 so the picture you attached is a great help.

Are there serial numbers on the block and head that can identify what year they are from?

Is there an easy way to crank a 97+ from the engine compartment?

I think the only problem you might run into is the Compressor. They are different in the HO models so the bracket is different. You would still need a compressor out of an HO XJ for it to fit and then it would have the wrong refrigerant oil in it. When you mix R12 with the R134 oil it turns into a Vaseline like substance and will clog up the compressor.

You might be able to flush out the the compressor and refill it with R12 type oil and since the R12 gas has bigger molecules it should stay in the system with the newer compressor. So, I think everything will bolt up except the compressor. And I don't think the older AC compressor bracket will bolt up to the HO motor since they have different heads.

Did your newer XJ not come with AC? Or is it just broken? If it did not come with it, you are better off going to the UPull it yard and gathering up the stuff for that year to put AC in it. And even if it did come with it you are still better off trying to get the part you need to fix it from the Upull it yard.
If the compressors had the same mounting points then you could swap it over easily.

It sucks, I have been down this similar road before. I have bought or gathered stuff to do something like this and then to find out it wouldn't work. I did that with my transfer case. Now I have three of them. lol
Oh well. Live and learn I guess.

You could probably sell that R12 for a pretty penny and get everything brand new to do the AC in your newer XJ. lol! It is like $50 a can for it now.

Rebuilt Compressor $200
Condenser $70
Lines x3 $140
Dryer $25

Also, anytime you mix and match AC parts from different gas types you need to flush out the parts to get out all the oil from the old gas. It just coagulates and ruins your system and it won't work. Then you are out money and the time you put into it.


You can see below that they bolt up with an entirely different configuration.

Here is the newer HO compressor.



Here is the older Renix AC compressor.

Does somebody know the brand name of the OEM fan clutch (viscous) in the Jeep Cherokee Sport 4.0 6 cyl automatic 1997?

I have a parts catalogue for the 97-99Cherokee, but it doesnt state brands.
Mopar?Omix-ADA?Chrysler

THanks for your help!

Depends on the year probably, who has the lowest bid that year. I see a lot of Hayden trademarks on electric fans on all American makes of cars.
Hayden, Four Seasons and Omix-Ada all make fan clutches for our XJ's.

Since they are all OEM suppliers, I would imagine they are all about the same.
But from pictures I have seen of all three, the Four Seasons clutch looks the most like the OEM one. But the Omix-Ada parts I have bought and seen, seem to be of decent quality and finish.

If you go to Rockauto.com they have all three and you can look at the pictures to compare. They don't always have the cheapest prices, but they are usually competitive and have a great selection and supply of hard to find parts. I think it's like $60 to ship a fan clutch to Australia. I hope they have a good supply of them there. lol Yikes.

THanks for the reply. I have seen the same brands when I'm looking for parts, and was wandering what experience people have with them.

Since I'm Oz, dont have access to the many part shops that you guys have, but I've been online. Sometimes Amazon can deliver the same parts, however their " this item fits your vehicle" isnt always on the right track, unfortunately. Therefore, I verify the part on Rockauto and then choose who ever is cheapest to send it to Oz.

So, these brands are more or less comparable in quality, you reckon?

Underneath your electric fan on the drivers side, "two screws and a electric plug to take it out" you can see the top of your steering box. There is a lash adjustment on top of it with a set screw. As the worm gear wears you start to get play. You can adjust it a little bit and get rid of some that play. But you only want to adjust it a little at a time and then test it to make sure it is not stiff or binding. If it does, you have tightened it too much and if you drive it like that it will mess it up.

When you adjust it, put the box wrench on the lock nut, then use the Allen wrench to hold it from moving with the lock nut and lock it down. Start it and turn the wheels lock to lock to make sure it is not binding or stiff, if it is you need to back it off a bit and re-test.

Remember that the worm gear is not going to wear evenly since you really mainly only steer a car a quarter turn to either side as you drive. Only when parking or ect do you use the outer edges of the worm gear. So you need to adjust it where it is best throughout the whole range of rotation.

So after an hour and 4 phone restarts ( my internet is being a huge pain) i got head casting #s to check the head of the motor that got swapped in by the po of the po. So i have an ho block and head with the renix intake and exhaust. When i try to take off from idle (5-speed) 8 out of 10 times it stumbles bad. I usually have to slowly press the pedal in till it hits 1500 or so rpm then its fine and i let the clutch out then go. Also when i let off the gas out of gear alot of times it'll drop almost to 100rpm stumble a couple times then come back to 800. Is the likely cause the mismatched intake runners? Or has someone else had this problem?

Modrod

Yes, I believe they are all pretty close. I have bought all three of these brands and I have not had any problems. I think Four Seasons specializes in heating and cooling, Hayden is mainly fans ect. and Omix-Ada I think makes all kinds of different parts. Most of the stuff I have bought lately for my XJ AC has been Four Seasons brand.

If you use a site like Autozone.com you can look up the part and get the info needed to match it up on Amazon. Autozone.com gives a lot of specs and measurements ect. so you can use that info to lower the chance of getting a wrong part. I know how much is sucks to wait for a week or more to find out it's the wrong part. UGH!!!!
lol
I hope this helps. If you ever have questions about fitment or anything else on parts, let me know. I don't mind doing some research for you or directing you to a site that can help.

The problem is that the Renix intake and exhaust is not compatible with the head. They do not line up correctly to the ports. Sounds like they installed the newer engine and tried to put on all the Renix compatible stuff so it would be easy. Best thing would to have used the short block of the HO and the head off of the Renix. Then all the intake and exhaust would have worked and been compatible. The heads and block of the HO and Renix are compatible and interchangeable but you have to keep the intakes and exhausts with the heads they came with.

Check your vacuum and make sure you don't have any leaks. Listen for hissing. The intake gasket may be leaking. The intake bolts could be loose also causing a vacuum leak.
