Been searching a bit Adam and it looks like the switch threads are M22x1.5.

Does anyone know the thread size of the bung hole in the Renix radiator where the fan switch / temp sensor screws into? Is it a standard pipe thread? Or even the p/n of the switch itself would help.

Your wheels were used on the 84-86 model XJs and MJs only. And the red stripe doesn't show up in any of my MJ manuals, so maybe it was GrandDad installed. Longbeds rule! 8)

The grill is wrong for your 91- it's for 90 and below models. You need the one-piece XJ/MJ 01-96 grill with the built-in bar on the top like below - black in your case. Nice truck - keep 'er going. :thumbsup:

Me too. Only 6" width though................. http://www.getallparts.com/jeep-cherokee-1984_p-47622-premium-surefit-15x6-aluminum-alloy-5-slot-wheel-rim-1401.aspx

Nope, it won't. Didn't notice you had an 86...........

I had to go through this when I put the cowl hood on as it didn't fit worth a d&%n. On yours, the horizontal bar on the right side hood latch needs to be lowered. Try a piece of 2x4 and a BFH to carefully tap the latch bar down - you may luck out and it will move down enough. Otherwise you need to pull the battery, loosen the latch mounting bolt, and pull some shim washers out at the bottom near the radiator support until the hood lines up correctly with the cowl. PITA to get to............... Then the whole hood needs to be centered by shifting it to the right. This is done at the hood hinges - loosen the hinge arm nuts and tap the hood over. Take your time and be patient. You may need to repeat the adjustments several times until it's right.

I bought four of these HERE in 2012 for $100/ea shipped. The Grey Tan with a Machined Face style. All matched perfectly, no differences. Then I bought one more a couple of years later for the spare. It matched the original four.

Relocation.

I like the color. :thumbsup:

The Unichip allows you to tune the MAP, TPS, CPS, and IAT outputs to the ECU. The Unichip maps are proprietary, but you can buy the program and tune yourself if you want to. I never did though; always went to Hesco for tuning on the dyno, otherwise it's just guesswork and I don't believe the butt dyno, not even my own. :yes: After a few years my truck started cutting off intermittently, and after troubleshooting it turned the Unichip was causing it. It would run fine bypassed, but when the bypass plug was pulled the cutoffs soon started again. I sent the Unichip back to the factory in WA for testing, and a tech I know there retuned it for his BMW. It worked great for him for three months. He sent it back to me with a milder Jeep 4.0 map loaded in and I plugged the Unichip back in. Soon the random cutouts started again. I got sick of it, put it up on Ebay, and sold it to a guy in Brazil. He's still running it today on his Wrangler and loves it. :dunno: You can tell the Unichip is gone on the stroker, but not so much under 3K RPM. But over that is when the tune really kicks in. I'm older now, and don't drive as stupidly? as I used to, so I really don't miss it. Oddly enough, the Unichip gave me about a 2MPG mileage improvement. The Hesco 10* timing advance CPS was developed to go with a lumpy big-lift cam Hesco sells, but according to them the CPS works well in some stroker engines too. I've got a spare CPS I'm going to modify one of these days so I can slide the pickup on the mounting bracket and adjust timing incrementally to see what works best. Altering the CPS pulses' delay to the ECU is the only practical way you can change the 4.0's ignition timing. Rotating the distributor only changes injector pulse timing. As you know, the 96 was the in-between year for OBD1 and OBD2, and uses pieces from both systems. The MAP sensors are the same for 91-96, except the 96 is throttle body mounted and is the one I use on my OBD1 engine. The 91-99 distributors are the same except for the sync sensor pickup location; I use a 96 distributor. Also the 91-96 CPS's are the same and just use different connectors. 1997 was the year the full OBD2 system was fully utilized. I can use my Actron reader/analyzer to read and reset fault codes and also run test programs just like you can with OBD2 readers/analyzers. So I have no need for OBD2 since it's pretty easy to vary the tuning inputs to the ECU that matter (including timing) with OBD1. But as far as I know, OBD1 ECUs can't be re-flashed. Anyone know?

John, Hesco has a CPS for OBD1 (unadvertised) that will give up to 10* advance. You just have to solder the proper connector on from your old CPS.

That's how I did mine - on the ground. L-LCA, then R-LCA; L-UCA then R-UCA. Don't know about the adjustables as mine were fixed. I used shims on the WJ LCAs to dial in caster.

Well, outside of the lake out back flooding and rising halfway up the back yard, my pier being out of site underwater, and my trusty fishing boat getting underway and is now missing at sea, it's been good. At least the power is hanging in and no tornadoes have touched down here, so it's not all bad.

Yes, I had it dynoed at Hesco after the 01 manifold install about seven years ago. Just the manifold resulted in a 12HP gain. This was on a stroker engine though with intake, exhaust, cam, etc. mods. It's unlikely a NA engine will see anything close to that. Image Not Found http://www.jeepstrokers.com/forum/viewtopic.php?f=5&t=387

So using a 99+ intake on a Renix should wake it up better than the 98 and below square HO intake it seems. It sure helped my 91.

:dunno: Can you use the early 91-96 intake manifolds on a Renix? I know the ports may need a little massaging and throttle body mods. If you can, then you can use the better flowing 99-04 intakes also as the ports are all the same throughout the 91-04 4.0 years

99-04 4.0 intake manifolds were all the same.

The Wranglers and Grands had 4.0 engines in 02 and beyond. If that is what you are referring to, yes it will bolt on. Then you will have to adapt your power steering pump mounting to it, adapt the Renix throttle body and sensors, reroute the serp belt, and redo all the vacuum lines. Plus a lot more I'm forgetting...........

I put one of these on my 96 XJ when I lived in Guam. It took awhile to get to Guam, but it was an easy install and it worked great with a 30" tire. Sure would like to find another and adapt it to an MJ.......... Image Not Found

Hummmmm, interesting..........

I thought everyone knew that...............
