2005 Jeep Grand Cherokee idler pulley broke resulting in a need for replacement along with the serpentine belt.
My 2005 Jeep Grand Cherokee(4. 7) with 58,000 miles overheated and stalled as I was pulling a small cargo trailer. The Jeep is equipped with a transmission cooler and up until this incident I've had no overheating problems. When I popped the hood there was coolant every where. The Jeep was towed to service garage and was diagnosed with a failed water pump. The day I picked up my "fixed" Jeep I noticed a strange sound coming from the engine . . . I took the Jeep back to my service garage and they told me my a/c compressor was failing and upon checking with the local parts supplier, my mechanic told me he could not buy a replacement compressor . . . I must go to a Jeep dealer. I did and was told there was a national back order and I would have to wait at least 3 weeks for a replacement. Keep in mind the engine has one belt, so at any time the compressor could freeze up and I would not be able to drive the vehicle once the belt broke. I did a lot of phone calling and found a compressor in illinois . . It was delivered and installed for $550. 00. So, within a week I spent over $900. 00 for repairs. The Jeep was a dealer demo, so I was out of warranty even though I bought the Jeep with less than 1,000 miles on it.
