It is essentially a safety device that is supposed to break if the impellers seize allowing the pulley shaft to still spin and the engine to be able to run. IF it did break, you will get no boost at all and you would probably hear nasty noises as the pieces would probably be banging around against the impeller gears. What exactly makes you think the coupler may be broken? You didn't mention any symptoms.
the grinding noise has gotten super loud, and there are other loud scary noises. i thought i lost boost, but once, it did go up to about 1psi (i wasn't trying to get boost). when in idle, it's at about 10 in hg, and the car rocks back and forth. i think it's from the tensioner. like something is resisting the belt, so it makes the tensioner go back and forth which rocks the car. there seems to be a lot of belt dust everywhere, but that could be because i installed the URD pulley. i hadn't checked under the hood since the installation.
if i give it a little gas to about 2k rpm, almost all of the symptoms dissapear. it took awhile, but the cel finally came on. i checked it and it gave me the following: P0402, P0300, P0301, P0302, P0402 (again). does that mean it's a lot more serious than just my s/c?
on the positive side, i have been biking to work, now that the car's broken. finally getting some exercise.
thanks
