1999 Buick Park Avenue Water Pump Removal

1 bolt is stopping me from removing my water pump. It is hitting on the idler pulley. I cant remove the idler pulley because the motor mount is in the way. I removed all nuts,studs, and bolts from the motor mount and lowered the motor but i can't get the studs on the mount to clear the bracket. I cant get the whole mount assembly to come away from the fender cus it hits the pulleys. This is a 3.8 Turbo and the pulley blocking the bolt does not have holes in it to access the bolt. I know there is something i am missing. All i can do now is stare at it and hope the water pump falls off. Any help would be appreciated.

    Ahh yes , the old , bolt burried behind the pully trick. Almost every car has one , and a different trick on how to get it out. Wish I was familiar with your engine so I could offer more advise than...... hope one of the holes in the pully lines up with the offending bolt when you turn it.

    Sorry , when I posted the other user has same problem , I was thinking it was your water pump pulley in the way. then I read your post again to see that it was the belt idler ( tensioner ) pulley.

    either way I hope it's laying on the floor in the morning.

    I found haynes manuals at my local library once that helped me through a problem till I got my own. Any chevy 3.8 from that era should be almost the same.

Hi once you have all the bolts off for the mount raise the front of the motor up till you can remove the center part of the mount
I use a floor jack and a 2x4 across the oil pan then remove the studs for the motor mount bracket now remove the bracket and now you can get the water pump out
hope this helps

I want to remove old water pump on 96 Park ave. and have all bolts out except 1. Its a long bolt and a pulley is in the way. How do I remove that pulley/ I have the right fitting, but I cant seem to brake...

You should not have to remove any pulley besides the water pump pulley.This is the only pulley you need to remove.Take a good look and make sure you are not removing more than you need to.There should only be 8 bolts.There are no reverse thread bolts on this engine.Hope this helps.Good luck.

1999 Buick Park Avenue water pump removal

that is not an idler pully that is the power steering pully if you feel through the holes in the pully you will feel the 13 mm head bolts that hold the pump to the block remove those bolts the pump will drop down and you can then remove the water pump also you have to remove the studs using the inverted torx end on the stud to unscrew it then the mount will come out
