I have no idea why you can't find it or don't remember it. I certainly don't have it -- I never worked at a dealership. I saw it when I had the job done, but that was 22 years ago.

Sorry, but that's incorrect. It wasn't a recall, but there WAS a TSB to cut out the C101 and splice all the wires. It came out in late '89 or '90. The difference between a recall and a TSB, of course, is that the customer gets raped for the TSBs. I had it done on my '88 Cherokee, and it resulted in NONE of the improvements the service manager told me it would generate. So on the Comanches I leave the C101 intact. This is different from the CPS bypass. That was a separate harness that got run through a new hole in the firewall, directly from the CPS connector into the ECU.

Not a silly idea at all. And if you know how to solder, eliminating the plastic is easy -- a copper tee, a couple of very short lengths of copper tubing, an elbow or two, and you're done. A ball valve as a seasonal shut-off can be added anywhere in the hose, or made up as part of the copper 3-way fitting.

Valve "adjustment"? The MJ engines used hydraulic lifters, and the retainers get torqued down on a shoulder. There is nothing to adjust. Does the R&R for the pistons include the price of the new pistons and wrist pins? What do they mean "rods turned and polished"? How do you "turn" a connecting rod? Are you sure this shop has ever seen the inside of an internal combustion engine?

To gravity bleed, you open the bleeder and leave the cap on the reservoir loose so air can get in. It's a PITA doing brakes that way. I'm 99.837 percent certain it won't work for the clutch.

Correct. Both the Pioneer and Chief trim levels included gauges, but the tachometer was an extra-cost option. The gas gauge was a biggie that occupied the space where we expect to see a tachometer.

Nope. Even early '89s had it. It was removed as a mid-year '89 production change.

The problem is -- if it's a factory slider, the glass is NOT flat. It's curved, and that means it needs a factory replacement ... which is not available. I have two factory sliders that have busted glass, and even my friends in the glass business haven't found a source.

He stated that his truck has gauges. There is no need to change senders.

Find your CPS connector and follow the harness from the connector upstream. If it remains a single harness -- all by itself -- directly to the firewall, most likely your truck was upgraded. There was a TSB a number of years ago about the CPS harness being too long and the signal degrading between the sensor and the ECU (which is under the dashboard in the Renix trucks. The fix was a replacement harness that went straight from the CPS connector through the firewall into the ECU.

A couple of years ago I asked when I was at the shop that does my emissions testing. I think their estimate was $600. That was just for labor.

Thanks - I expect to bring the "new" XJ home Thursday or Friday. Then I'll see what I can figure out. Yes, I would prefer to keep it Jeep, but if I can go aftermarket for $30 compared to spending a hundred to be purist ... in today's economy practicality is going to have to win. If this were a NEW XJ, then I'd be more concerned with keeping it all Jeep.

Connecticut has not allowed pick-your-own junkyards for more than 25 years. And I doubt I'd have any luck trying to get a yard to go scrounging through XJs to look for one with the keys (and remote) and the unit. It makes more sense just in the gas I'd waste to buy aftermarket.

Which temperature sensor are you trying to replace? On an '89 there are three: The one in the radiator tank controls the auxiliary fan; the one down low on the driver's side of the block sends data to the ECU; the one on the left rear corner of the head is the one that activates the idiot light or the temp gauge.

The seller said he is not the original owner, but he has two keys and no remotes, so I'm guessing no remote entry. So I think I'll spring for one of JC Whitney's Valiant brand aftermarket units. The question is, which one? If anyone knows much about aftermarket alarms I would appreciate advice. Be advised: Price IS an object. The least expensive one I'm looking at is $29 and the highest I'm considering is (IIRC) $69. This is an eleven year old used car we're talking about -- I don't want (and can't afford) a $200+ all-in-one system that locks the doors, has an alarm, disables the starter, and offers remote start capability. I really just want remote entry, but if a modest system that will do that doesn't cost any more with a basic alarm function, so much the better.

Probably because that's what AL law says. The laws of each state are different, ya know. In my home state, without a carry permit we are only allowed to transport a firearm from the shop to home, from home to a shop to sell it, and from home to a repair shop and then bring it back. Beyond that, I can't even stand in my own front yard with a handgun if I don't have a permit. Can't take it outside of the house. Definitely can't take it to the range or have it in a vehicle -- even if it's not loaded.

That's to simplify their inventory for service departments. They don't want to carry the correct fluid for two transmissions that haven't been used in years. Don't both Amsoil and Redline offer gear oils that don't have sulpher compounds? Yes... Redline MTL and MT-90 or Amsoil MTG are all intended for transmissions that contain yellow metal parts. Hmmm. Now, if we only knew an Amsoil vendor. Oh, wait ...

I haven't picked it up yet so it's not here to check, but it is a Sport, not an SE. I thought all Sports came with remote entry, but the guru at the stealership says they all had electric locks, but they did NOT all have remote entry. Once I get it, I'll have them run a build sheet from the VIN. I'll add remote entry if I have to, but it would be nicer if I could just program the remote from my late, unlamented '99 WJ to work with the "new" XJ.

It appears that I am buying a 2001 XJ Sport. It has electric locks, but it doesn't appear to have factory remote entry. There are aftermarket systems that can handle this, but there are enough of them that trying to compare makes my head hurt. And it looks like I can get an alarm system with remote entry for $2 less than a simple (?) remote entry system without an alarm feature. Go figure. Looking at wiring diagrams on-line, it seems there are three types: positive trigger, negative trigger, and reversing polarity. Does anyone know which type of control wiring Jeep used in the 2001 XJ?

I believe the 2.5L and 4.0L use the same CPS.

The SporTruck was the base model. It didn't have cloth seat and it didn't have carpets. You are probably looking at a Pioneer. Although, with black bumpers and window trim, it may be a Chief. However, I would not put any faith in what the build sheet reports, because Chrysler recycled a lot of the AMC option codes for other things. I have seen build sheets listing things that were not EVER available on the MJ or XJ, in any year.

If possible, get into the kick panel areas beside the footwells and unplug the speaker wires and (if electric) the window and lock wiring. The biggest thing to remember is that a complete door assembly is HEAVY. Either prop up the back end of it while you remove the six torx screws, or bring a husky friend to help you wrestle with it.

But the question was about an AX-15, which goes behind a 4.0L. That's what is in my '88 MJ and there is no interference with the dashboard in any gear.

No it won't. My '88 MJ has a YJ AX-15 in it, complete with the long, straight shift handle and the YJ transfer case shifter (which the previous owner had to saw the knob off to clear the dashboard -- which may be the cause of the confusion). The transmission shifter is fine even with the taller, straighter YJ handle, and would be perfect with an XJ/MH handle. There is no interference with the dashboard.
