Absolutely no complaints or problems with this part. I had to build a water pump on my car anyway and as hard as it was to get to that area (some disassembly required) I decided to replace ALL the idler pulleys, serpentine belts, thermostat, tensioner and such. I would just hate myself if I didn't do it all at once and I had a problem in a few weeks or months, I hope this lasts 127,000 miles!
