Serpentine belt removal 1998 Buick Park Avenue

Here you go.
REMOVAL PROCEDURE
The accessory drive belt drives all engine mounted accessories. All driven accessories are rigidly mounted to the engine. Drive belt tension is maintained by a spring loaded belt tensioner. A belt squeak when the engine is started or stopped is normal and has no effect on belt durability. The drive belt tensioner can control belt tension over a broad range of belt lengths; however, there are limits to the tensioner's ability to compensate. Using the tensioner outside of its operating range can result in poor tension control and/or damage to the tensioner.

Important: Ensure that the wood block extends past the width of the oil pan in order to avoid damage.

1. Use a jack with a block of wood on the jack under the oil pan in order to support the engine.
2. Remove the engine mount to engine mount bracket nuts.
3. Remove the engine mount bracket front upper and lower nuts.
4. Remove the engine mount bracket front upper and lower studs and spacer.

5. Lower the engine as necessary and rotate the tensioner to remove the drive belt.

6. Remove the drive belt.
