2006 DTS, approaching 100,000 miles. I changed the water pump belt and tensioner. About to change the serpentine and idler pulley (preventive maintenance). Never even thought about the serpentine tensioner....is there any reason to change that as well? Pulley looks to be in good shape on the tensioner.
Thanks

I have not changed mine on the 97 136000 or the the 06 93000 but that's not to say It wont be a good idea to do so.

I would suggest if you do, that you use a new bolt or put lock tight on the old bolt. (the blue stuff not the red).

To me it would be like flipping a coin. Mike
