Need service information to conduct a thermostat replace ment on a VY series 2 commodore which has the supercharged buick 3.8 engine


Sorry Graham, it is based on a Buick, the big difference is your 3.8 does not have a distributor at all, no where for it to go even, you have to start with your fan belt using a 3/8 drive bar that fits into the flexible belt tensioned, then remove ALL the plastics from the front of your engine, the water pump is under them, not a nice job so I would look at replacing any belts bearings and seals as you go

Supercharger is making a knocking noise at idle. Is this normal or is something wrong?


Something wrong, common noise when the bearing is warn and should be be driven till bearing is replaced. Internal supercharger parts may break loose and run through the engine causing expensive repairs such as engine replacement other then the supercharger.
