Motor mount is in the way. The answer on your forum did not address this problem for a supercharged 1997 Buick Riviera.
Do you

The supercharged 3800 engine uses two accessory drive belts. The outer belt drives the supercharger. The inner belt drives the generator, power steering pump, coolant pump and air conditioning compressor. All driven accessories are rigidly mounted to the engine. Drive belt tension is maintained by the spring loaded belt tensioners. Each belt has its own 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 due to stretching; however, there are limits to the tensioners ability to compensate. Using the tensioner outside of its operating range can result in poor tension control and/or damage to the tensioner. The belt should be replaced when this condition occurs.
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 torque axis engine mount bolt at the engine mounting bracket.
3.
Disconnect the electrical connector from the crank sensor NOTE: install belts and reverse procedure.
