    I have a 2003 Jetta TDI and I'm doing the timing belt and was wondering if it is ok to use never sieze on the water pump bolts.Our first belt change was done at the dealer and the bolts came out ok and I don't think they used anything. Thanks

    I wouldn't. The bolts don't have a history of seizing up.

    tdi's vibrate you don't want them to become lose easy. I personally used red tread lock when I did my TB. After 80,000 miles of vibration they will come out easy if not I can heat them with a torch for 3-4 seconds and everything is back to normal.

    I wouldn't use red LocTite there... blue's fine... yes, you definitely don't want those bolts backing out... ask me how I know...

    I can assume you had problem with the TB tensioner bolt backing out from vibration and breaking.

    I thought we're talking about water pump bolts... there are no TB tensioner bolts... studs and lock-nuts... Yes, I've had a water pump bolt back out... needless to say I got to practice my timing belt replacement routine earlier than expected...
