I need to replace a timing belt and the mechanic recommended replacing the water pump and tensioner at the same time even though none of them are actually in need of repair. It is kind of expensive too. What do you think?
This is standard procedure. For this job it's not the parts that cost you the most, it's the labor. While they are in there doing the timing belt it is advised that you replace the water pump and the tensioner since it would cost so much to go back and do it later.
I replaced both of these on my vehicle when I did my timing chain. It took my almost 10 hours to do the job and I wasn't going to risk having the water pump go later and have to do it all again!
