My 04 has decided she needs some garage time. It started as a whiff of coolant last week and yesterday, i thought I lost PS fluid. Pulled into the nearby convenience store, and noticed it more. So, Lib is in the garage and new parts in hand. Now, it makes sense to : 1 - replace the valve...

when you pop the door panel off and dig in, you will find the plastic tube that the cable lives inside has cracked open. you "might" get a temporary fix with some larger diameter pvc tubing and splitting it lengthwise to cover the break, sort of like a sleeve. Leave it a bit long (6 inches)...

Both at the same time. Did just the evap once and heater core about 4 mos later. Lots of adult language issued, even though it went faster that time.

2002 plus , but the concept is similar.

Not sure about this, but do a bit of searching about the SKIM module. It is the electronic theft control. Do you get any start and immediately shut off? There is a red light on the dash that lights up under conditions.] I gotta check my 06. Don’t think he is drive by wire, but the the...

I’d look hard at the fuel pump. Sounds like it is bleeding the pressure off the line when off. Ideally, it would be hard to start no matter the inclination but maybe yours is just starting to go. Next time on the hill - try to power cycle the key a few times before trying to start. If it...

last one i bought with a 'bad' transmission was my 06. I crawled under the day I went to check him out. Gal told the transmission slipped pretty bad. As I was under the jeep, I noticed the 'bad' transmission leaking fluid. Right in front of the pan. Turns out, the clip holding the cooler...

Gonna need a lot more detail for us to sort this out. Starts and immediately dies? - Look for flashing lite on dash - security system SKIM/SKEE module or programming. Starts and runs for a minute or so? Fuel pump most likely. Starts runs drives a few miles ? Need a lot of info. So - What...

If you are friendly with the parts guy at your dealer, he may be feeling generous and give you the code. My dealership service advisor wanted to charge me 90 bucks for it. So i ordered some stuff and got up with the parts guy who slipped me a paper with the code on it. Lunch was on me !

Maybe start with looking at pending codes for the ABS section. My 06 lost his mind a few times like this and in poor traction areas would fire the warning flares like that. Eventually I found a bad wheel speed sensor on 1 of the front hubs.

2 schools of thought here - 1 - try to do the job without loss of ac. I wasted a LOT of time doing my first kj like this, only to have ro repeat when the evaporator core needed replaced a few months later. Most do not pull the hvac box totally out and do a lot of wiggle work. 2 - replace...

Couple things: confirm that you have good flow out of the hoses coming into the heater core. Should be good and hot. If not, consider plugged plumbing there in that ‘trombone’ looking bypass hose, or a waterpump issue. My 04 had a plugged core that i verified by running a hose to one side of...

Couple things - Did you use the Mopar thermostat, and get it installed correctly, with the air bleed in the right direction? Assuming you did and used the HOAT / G05 coolant, I would be thinking water pump all day. The impellers get eaten up or break away from the shaft.

Just the lifter -(lash adjuster) - unless the rocker looks worn. imo - when my 06 did it, i replaced all 12 adjusters. Being a used engine of unknown stats, that just made sense to me.

There are no spark plug wires. The 3.7 uses coil over plug arrangement. Replace the plugs with the NGK copper ones, nothing fancy. If you want to do coils, Mopar or Standard motor products. Helpful hint: These old KJ jeeps are extremely particular with electrical components. Do yourself a...

If it is a rocker, little to none, possibly. I had my 06 throw 2 off back last winter because the lifter collapsed with the low oil pressure at start up. I was dumb enough to drive a mile home, and lucky enough that the only issue was rough running. Think of it as a hard miss, because one of...

Hard to say right off, but i think i’d pull the valve covers and have a look for a thrown/broken rocker. But I did not hear the noise, so it is just a guess.

stat - thermostat - follow lower rad hose back to the block. It is on the right side of the engine (left side as you look at it). Pay special attention to the orientation of the little brass button on the stat. It is an air bleed and it does make a difference when you put a fresh one back in.

Overheating and visual on the belt is your clue. Bad water pump all day. I would bet misaligned belt, but your shot is pretty clear, so I am voting WP. Replace the stat with a Mopar stat, and tensioner while you are in there. Only other that could cause mis-alignment issue is the PS...
