No, you do not need to remove the torque axle bolt to replace the serpentine belt on your 1995 Buick Riviera Supercharged Series 1. However, you may need to use a serpentine belt tool to relieve tension on the belt before you can remove it.

Have you tried looking at EBay? I did a quick search and found this. Not sure if this is what you are looking at but certainly there would be a matching pigtail. Otherwise a junkyard (call before you go) and you can probably get one from another GM car. Full size gm chassis with the same engine

If I remember correctly, it should be on the drivers inner fender in front of the left front tire under the hood. Seems like it should be hiding behind the washer bottle or the coolant reservoir.

Float setting and needle valves are big issues here with what you describe.

IF you have a serpentine belt it's not a matter of adjusting the power steering belt tension because it's done automatically with a serpentine belt tensioner. OTOH, if you have a separate V-belt you'll need to loosen the mounting bolt/nut at the bottom of the steering pump and the adjustment bracket then tighten the belt by moving the adjustment nut to tighten the belt. You might be able to google a video of your particular engine power steering belt adjustment.

If you lost a vacuum line then the heater would let hot air out the vents with or without the fan motor running. Do this test with the engine up to operating temperature Touch both hoses with the heater on and temp control to the hottest position. Now check the temperature of both hoses. They should be the same. If not that indicates a blockage of water to the heater core. Test the water flow valve too. It can be plugged with rust or not moving to let water into the core. The core itself can be plugged too. If you really need a hose diagram, a Chilton's manual will be your source of information. The engine won't idle well with a vacuum hose off.
