I found a wrong serpentine belt tensioner installed after servicing by an independent shop. This weekend my in-laws asked me about a bad belt squeel they were having with their Dodge mini-van. Since my wife and I were spending the weekend with them at their timeshare, I said I would take a look when we meet up. After I got there, I went for a drive in the in-laws' car and it squeeled like crazy at all speeds. Definite belt slip. So I take a peek under the hood. I concluded, without a doubt, the "mechanic" who serviced their car before their trip installed the wrong serpentine belt tensioner with the new belt. The tensioner was too narrow, by about 25%, for the belt. How hard is it to look at the belt, and then look at the tensioner, and notice that they do not match up? The tensioner sliced the belt along its entire length and the new belt was now about 1/4 of its width narrower, with one side jagged its entire length, The belt now matched the width of the brand new tensioner and the belt was correspondingly about 3/4 the width of all the pulleys. The tensioner, since it was for a skinnier belt, probally had less spring tension than the correct tensioner. Unbelievable! There were no belt fragments left under the hood, but they drove for about 900 miles with the belt squeeling, so they must have been long gone, go figure.
What is even more odd, about 300 miles before I took a look, the water pump failed during their trip and the car was towed to a shop, and the wrong tensioner went un-noticed. The ragged belt was removed to put a new water pump on and the same belt re-installed.
I showed my wife's brother-in-law what I found and I highly recommended that someone local fix this before their return trip. I just did not have the means to replace the tensioner myself. His response was, "Well, it made it this far, it should make it back so I can take this car back and have it fixed correctly."
I have no idea if he and his family made it back, my wife will call them a little later today. This guy knows nothing about cars: the engine was just filthy, the brake fluid in the reservoire was black, and one of the battery terminals was so corroded it was about to fall off! The car was quite neglected. I am just glad I don't have to live like this!
