XJ Ask the Question Thread
No, I don't lick fish.
Hey guys so I did some research but still have a few questions.
Last night while driving my headlights went out. The dashboard lights, signal lights, rear end lights, and interior lights were all still on or working. I've checked the fuses and did not find any issue there. My highbeams were not staying on but they were working. I read that it's probably the headlight switch or the signal switch or both. So my question is, is it both or could it just be one of the switches? Or is it even a switch at all? (Sorry for the newb terms) I also read that the interior lights will usually go out with the headlight switch (which mine didn't) so maybe it is just the signal switch and maybe it's interfering with the headlight switch??? Anyway! Any help to save this little ladies butt and her babyblue would be much appreciated. Thanks

This will not only increase power output to the headlight, but it will also take voltage load off the headlight switch itself.

Hey guys. Just put in a Delphi steering box in my Jeep (#19321270 and supposed to be a direct replacement). It seems like the nut that holds the pitman arm is different then the factory box. It looks like the factory nut is a 7/8 x 14. Is there any chance that my new box has metric threads instead? If so, do you know what size the nut is? From everything I can tell its a 1.75 thread pitch (with is almost identical to the SAE 14 thread pitch) but dont know if its a 23mm or 24mm. Or do you guys think its the same thread as the old box and I just have some messed up threads on the new box? The nut only goes on a 1/4 turn right now.

Ac compressor trouble
On the trip back to nola yesterday my ac stopped blowing cold. I figured I was just low on freon but at some point the compressor started making noise.

The clutch goes in and out a great deal and a puff of smoke shoots out right when it engages.
Will a clutch kit fix this or am I going to have to sell a lot of belongings?

Might be a shim issue:

Also check to see if you can rotate the compressor by hand, it might be seized up. Grab the center part of the clutch assembly and turn in the normal direction of rotation. There will be some resistance but it should turn smoothly.

Is there a reliable way to keep moisture and debris out of the ac fitting? For now I just taped and zip tied a sandwich bag around it but I know that's not doing much to keep undesirable stuff out of my ac system until I can get it back up again.

I was able to turn it by hand but it was plenty gritty. Made it to church but it got much worse. Ended up getting a bypass pully until I get another compressor or rebuild this one if possible.

So you'll need to flush the system out, but the parallel-flow condensers used in R134 systems are a problem. If metal shards are lodged in there it's likely the flushing compound will just route around them. Then later they can come loose to create havoc. So the safe thing to do is replace the condenser. Ditto for the evaporator if it is parallel-flow. (Not sure if that's the case on the XJ.) Of course you would also need a new drier but that's going to be the case whenever doing major work on the AC system.

The biggest problem is that when a compressor fails internally it tends to send metal shards into the AC system. If left in there this will ruin the new compressor.

Have been wrestling with bad cold starting (doing the poor man's prime) and based on what I'd learned here, decided to replace the fuel pressure regulator, and did the fuel pump and filter while I was at it. Sadly, no real improvement. What's next? Check for a leaky injector? Already replaced the IAC.

You would check the clutch pulley bearing by removing the belt and freewheel spinning the pulley, checking for any looseness, noise, or roughness.

So I have this sneaking suspicion that my head gasket is leaking, but I'm not sure. It's a 98 with the original 4.0 engine. 230k on the drivetrain.
Here are some data points:
There does not appear to be any oil in my coolant or coolant in my oil.
I'm not mysteriously losing coolant (that I can tell).
Fan clutch replaced last year--temps creeping up at idle, clutch tested bad.
Water pump replaced this summer--metal flakes were in my coolant.
3" lift, 32" tires, stock gears.
Bumper, winch, and light bar hanging off the front:
So here's what I'm seeing. When the ambient temperature is high-ish, like the 90F it was yesterday afternoon, my temps creep up in the 240-245 range when I'm going at highway speeds. I'm fine at lower speeds in that heat, or at highway speeds when the ambient temperature is lower (it was 70F this morning and it was fine).
I monitor my temperatures with a ScanGauge because the instrument cluster is a dirty liar.
While I was researching something else, I came across someone who said that overheating at highway speeds but not at idle can indicate a head gasket problem.
But I wonder---would ambient temperatures really have that much of an effect if I was overheating due to a blown head gasket? Or could it be something else?
I'm borrowing a compression test kit for the weekend to try to get that done.
