    I was more interested on why you assumed HGs as the cause for a sudden overheat.

    The whole job isn't very difficult. The drive pulley can be gotten from a salvage yard, but you'll want a new tensioner pulley. Not expensive at all, any major manufacturer will do. $20-$30.

    Yes, it is.

    The shield needs to be removed. The drive pulley MUST be removed and installed with a power steering pulley tool. There may be a plastic cap in the pulley bolt, removed with a Torx bit.

    IIRC, the tensioner pulley can be replaced without removing the tensioner.

    A 1/4" drive ratchet is used to move the tensione arm, to install the belt.

    I did this job a few months ago. Easier and quicker to replace the pulley & tensioner together. Sold as one piece. Plus tensioner can lose strength with age.

    you should be able to "rent" - the puller - for free -
    from autozone - or other large auto parts stores -

    and YES - it MUST be the power steering pulley tool -

    Ahh, maybe this '99 have some life left in it.

    Yes the WP is under the black shroud. That's the tensioner pulley that disintegrated. Now check the plastic drive pulley on the intake cam. That generally melts when the tensioner pulley seizes. If you need to replace that, be sure to use the proper puller (DO NOT use a 3 jaw gear puller).

    No, belt & tensioner pulley/tensioner can come out with water pump & water pump cover left in place.

    GM part number for belt = 12588412

    For tensioner & tensioner pulley = 12555153

    Numbers are for an 02.

    Just wanted to point out that i said there was no coolant after the overheat. This still sound normal even though it was the belt failing

    Some could have gone out the overflow.

    Have you refilled it yet?
