    Anyway...

    When getting the water pump and timing belt swapped, should I get the tensioner done too? My brother had his beloved Jetta VR6 destroyed when something with the tensioner failed around 110,000 miles. Kinda wanna avoid that unless it isn't usually a big concern on the 3.2L engine?

    My recommendation is to replace the timing belt, tensioners and Guides so you don't have to worry about it later on down the line. But I haven't heard much from 3.2 owners about timing belt failure.

    You can check to see if they are worn once you are in there and pick some up from the dealer if you need it.

    Do you mean to say you haven't heard much about tensioner failure from the 3.2L owners? Because I thought timing belts going out was an issue with the 3.2 after 100,000 miles.
    Anyway thanks, ill definitely take that into consideration. Hopefully it's all being done this week.

    I haven't heard or seen much about the timing belt failing for the 3.2 I'm at 140k on original belt still.

    Hmm...I'm assuming they are synonymous when both issues will kill your engine lol. If you are not concerned about the belt, then leave the belt on if it looks good, then, Change out the tensioner without having to worry about the timing marks being reset correctly on your engine (the timing chain DIY with the million pictures helped make sense of the two guides all data had for the 3.6).

    My mechanic and i agreed that the chain looked serviceable when we were in there but I changed it along with the guides and tensioners as a preventative measure .

    Just check the timing belt tensioners and idlers when you do the belt. I felt all of mine when I replaced the belt and no issues. Just rotate slowly feeling for binding, looseness, or dead spots in the bearings.

    Glad you got it fixed. I have an 06 Cts 3.6 with 40000 miles and had the exact same problems.Just replaced the water pump. Very easy to do.

    Re: Antifreeze smell ?

    Is the water pump leak noticeable?
    does it leave a puddle on the floor?
