Helllooo Is stole the following pic from this thread: In about the center of the pic there is a hose, with a yellowish plastic endpiece with a greenish cap. What is this for? Kinda looks like the breather on my 2016 JKU, except mine is in the wheewell...

Hello everyone. 2010 Jeep JKU Over the weekend we drove about 1.5 hr to the mountains then like 30 mins of driving a decent climb. During the climb I got a hot oil chime and the engine kept bogging down. I shut it off let it chill for a little and checked the fluids. When I started back up it...

I've been looking into swapping a 5.3 Gen 3 engine to my 99 Jeep 4.0 Thinking of keeping the AX15 Transmission and Original Gauges. It is A LOT of work for sure to do all this, any of you know who does these kinds of swaps around DMV area? And how much? TIA

Hi All: I appreciate your advice and yes i know I spent to much money already ... I am looking for some advice on replacing or upgrading the engine on my 1997 Jeep TJ SE. Normally, I would consider selling but I am in to this pretty deep; this was a father-son project and we put a lot of nice...

The wires turn with the nut. We tried holding the wires in position with needle nose pliers but no luck. We also used blast penetrating spray several times over 24 ,hrs. Too scared to cut the wires. Any tips or help appreciated. Thank you

I’m on the trail of this 2017 JKU Rubicon with 24k miles. It’s a “certified“ used. While in deal-making mode, I caught on to something being really odd on the CarFax (short: multiple oil changes by the dealer in a short period, including a month of just sitting) and started drilling into it...

2016 JKU. 3.6L Pentastar (stock). 6-speed manual. 78.5k miles. Yesterday, the Jeep ran rough through town. Checked the DTCs and it came back as P0303 (3rd cylinder misfire) consistent with the way the engine was behaving. This morning I swabbed the coil plugs of Cyl 1 and Cyl 3 to start the...

I bought a used 2015 wrangler unlimited with 45,148 mi on it. It now has a little over 47k mi on it. I was driving and it started to ride really rough and ultimately stalled when I stopped (automatic trans). It would take a lot to get going again with turning it on and off but thankfully made it...

It's the 4.0 with auto transmission. It was running completely fine until some one put a Bluetooth OBD2 reader on it. after that the engine wouldn't crank at all I don't know if the reader is related but, that is the order of events. I've had no starting issues before hand. The battery checked...

Hi all. I have been having trouble sourcing compatible HOAT engine coolant where I live for my 2009 JKU. I can get some OAT formulas such as Fleetgard/Fleetcool, and plenty of 'standard' coolants such as Total COOLELF, but from reading around it seems they can't be mixed with the Mopar HOAT that...

For the last few weeks, I've had issues with my jeep that are concerning me for a blown head gasket: 2004 LJ 4.0L I6, remanufactured engine due to my old one seizing up a handful of years ago. Overheating into the RED when stopped or at low speeds. Getting up to speed on the highway or 40...

So I just bought a 2003 Jeep Wrangler TJ SE 2.4L 4-cylinder and after a couple days of driving, I noticed the check engine light came on. There are multiple codes that come up during testing, which include 0340, 0123, 0320, 0352, and 1391. It runs fine for the most part. The check engine light...

Hi all, I've got a 2007 Jeep Wrangler Rubicon with the 3.8 auto combo with 173k miles. I truly haven't had any issues and would go as far to say between me and my buddies' jeeps it's a reliable powertrain if you run 10w30-10w40 oil in it and change fluids often like I do. I would like for a fun...

Noticed this after going for a short drive. What am I looking at here? engine oil/transfer case leak? how serious is this and how easy/difficult is it to fix? I marked the spots where I can see the oil dripping from.

PA: WTB 95 YJ 2.5L Engine Engine in my 95 2.5L started knocking, looking for a direct swap engine.

Man do I have a mess. I bought this 1998 TJ with a 2.5L in it. It ran good for about 6 months. When I bough it the oil pressure when at a stop would drop to close to zero. I changed the oil and put Rosella in it and it held for about 200 miles then started doing it again. The heat also went...

I am trying to figure out what other engines will fit in a 2013 JK. Will an engine from a Dodge Charger, Challenger, Caravan, Durango, etc. fit. They are all 3.6L Pentastar but are they interchangeable. Is there a cross reference that will have that information. Thank you to everyone for the...

Greetings from a small mediterranean country - Montenegro. I have 1995. Wrangler with 4.0 engine and 32rh auto transmission. I have it since 2012. After going thru hassle with all sorts of issues, shops etc. I have finally decided to do a complete rebuild on my own. Jeep was not a rust bucket...

I am in the market for a new to me Jeep. I have roughly $12,500 cash to put down on this new Jeep. The reason I have the cash is because my current car is paid off. Being that I don't have a car payment now one of my deciding factors with getting a Jeep is whether or not to have a car...

Hi everyone! I've been digging through posts/threads, but still not finding solid "how-to's" on cleaning my Jeep's engine bay. I think I'm good on products to use, but as far as what exactly needs to be covered (aside from air intake), how much water is really okay to hit the engine with (that...
