Do i have to remove motor mount in order to change serpentine belt on 97 pontiac bonneville 3.8 liter not the super charged. any tips or advice would be greatly appreciated

No it is not necessary to remove the motor mount on either the standard 3.8L or the super charged engine. Just remove the tension on the tensioner and remove the belt or belts, both will come off without removing the motor mount.

Hello! I'm not sure if you have the supercharged, or non-supercharged version of the 3.8 liter V6 - so I've posted both for you.

Supercharged L67 motor - Supercharger belt:





Supercharged L67 motor - Accessory drive belt:



Non-Supercharged L36 motor:




Hope this helps, and thanks for using FixYa!

Depends on the motor. If there is a mount on the passanger side that the belt goes around then yes. Don't fret though, easy to get around. Use a jack and a piece of wood on the oil pan to support the motor so you can remove the motor mount to remove the belt. Again, this is on SOME gm motors not all. On the others the mount isn't in the way at all.

YES ON THIS (3.8 LITER?) YOU MUST REMOVE THE MOTOR MOUNT TO REMOVE THE SERPENTINE BELT. NOT THE BEST DESIGN THAT I'VE SEEN. HOPE THIS HELPS. GOOD LUCK

I have a 97 Bonneville, you have to undo the passenger side engine mount. No joke.

Yes you will have to loosen motor mount and jack motor slightly to change belt.

it is on a sticker adhered to your radiator shroud.
if it is removed, damaged, or unclear...


one tip - if you look by the crankshaft pulley to the right you will see a tubular looking shaft about 1" diameter , you will notice you can't get the belt out from under this piece , it has a nut on it , once you take the nut off , you will notice it has a star shaped point on the tip of the stud , it requires a reverse torx socket or wrench to remove the stud , when you get the stud out the tube piece it can be removed , then the belt comes off , replace the belt , now comes the tricky part , fitting that tube spacer back into its spot , it can be difficult , once its in place put the stud back in , and put the nut on and tighten it.

You can remove the inner splash sheid inside the passenger wheel well and access the lower pulley.
