    Is there supposed to be a weep hole plug in the water pump?

    I've just replaced the water pump in my 05 Liberty 3.7l. I noticed that there is a little hole at the top of the water pump housing. On the old pump, there is some sort of plug in this hole, but there is no plug in the hole in the new pump. Is there supposed to be something in there? I haven't...

    KJ 3.7l A/C Bypass - is there a consensus on belt size?

    2005 Liberty KJ 3/7l 185k I made a post yesterday about a noise that was happening when I turn on the A/C. It sounded like rushing water, so I thought maybe there was air in my coolant, but that was incorrect - the sound is a bad bearing on the A/C compressor. I know this is quite a common...

    A/C noise, and a 'roaring' sound when I turn it off

    EDIT: It turned out to be the bearing on the A/C pulley. It sounded exactly like rushing water, which is why I thought it had something to do with the coolant. 2005 Liberty KJ 3.7l 185,000 miles. While I was driving yesterday, I noticed that my A/C was noisier than usual, like there was an...

    Low whistle and 'washing machine' sound while driving?

    I have a 2005 Liberty 3.7l with about 180k miles. I recently noticed a new sound while driving. It's difficult to describe, but imagine the sound a washing machine makes, but very quiet, like the washing machine is in a different room with the door closed. The sound speeds up and slows down...

    Coolant vapor 'smoke' pouring out of exhaust manifold

    Making a new thread, because I think my P0177 code was merely a symptom of a much worse problem. I initially thought I wasn't losing coolant, but it appears I was - I was looking at the 'cold fill' line when the engine was warm. I swapped out the temperature sensor and topped up the coolant...

    Check Engine Light with Code P0117. Doesn't appear to be overheating, and temp gauge seems to be working fine.

    I was driving home this evening when my CEL came on. I stopped at Advance Auto and borrowed their meter. There was only one code set, and it was P0117, which is apparently the coolant temperature sensor reading too low a voltage. My coolant level is fine, and the wiring to the sensor also...

    Creak/knock from driver's side wheel when turning left.

    2005 Liberty Sport, 180k miles. It is in stock configuration, no lift. When I turn the wheels to the left, I get a sort of creaking/knocking sound. It only happens when turning left, and only happens when I turn the wheels almost all the way to the left. The noise is exactly the same whether I...

    Liberty KJ 3.7l P0442 causing misfire?

    I'm not having much luck lately :( Last weekend, my 2003 Liberty 3.7l started shuddering at idle and the check engine light came on. Went straight to Autozone for a scan, and the code was for a misfire (I don't remember exactly what code it was). Their computer recommended either spark...

    Radiator Cap - Is This Normal?

    I've been having a hell of a time with my 2003 Liberty 3.7l lately. In the last two weeks, I've replaced the belt tensioner, power steering pump, spark plugs, and I need a new fan. Today I got a CEL for a misfire. I've replaced all the coil packs hoping that it will cure the problem...

    Weird Noise From Engine That Goes Away After A Few Seconds

    NOW WITH VIDEO - PLEASE SCROLL DOWN TO POST #9 I recently had a problem where my Jeep Liberty (2003, 3.7l, 130,000 miles) stalled and then made a loud rattling sound. I traced the problem to a bad belt tensioner and PS pump, which I have now replaced. It stalled again, so I took it to...

    I have a 2003 Jeep Liberty KJ, and it looks as though my power steering pump may need to be replaced due to bad bearings. (see my other thread here for details: http://www.jeepkj.com/forum/f196/please-help-engine-cut-out-grinding-noise-61597/) I'm going to replace the pump this weekend. I...
