Default FYI: Shreded Serpentine belt, runs w/o supercharger

Yesterday morning on the way to work the serpentine belt that drives the water pump, SC and AC compresser shreded. I first noticed something wrong when trying to accellerate hard from a stop light, no power.....

A few minutes later the 'check gages' light and dinger, the coolant temp was halfway into red!

About a mile further was a garage, so made it there and stopped. Had the belt replaced (would normally do that myself, but 45 miles from home, no tools, no parts, etc.)

Anyway, discovered the engine _will_ run w/o the SC, althogh performance is obviously down. Even able to start and move the car into the service bay.

I had figured that the engine wouldn't even start w/o the SC turning.

Did finally confirm that the SC coupler needs replaced, (about 1/2 to 3/4 inch slop in the pully) so I'll be doing that in a few weeks.

How did u drive with no Water pump??? You ran the engine up VERY hot if it was halfway into red. Might cause other problems to appear soon. Be very happy it'* an iron block, although .

Series II guys can do this, but now series I cause of the WP.

WOW..

Lucky theres no internal damage... yes I could've told you you could've ran without the */C.. but hella slo though.. worse then a N/A.

Sorry.. don't know your year.. so didn't know you only had 1 belt to drive just about everything.. mine has 2.. only 1 belt powers the */C.. other belt runs everything else.

The cylinder bores may be worn heavily from running that hot.

Solution? Electric water pump..

Well, the distance from when the check engine and dinger went off to where I shut is off was about 4 miles. i knew the garage was there, so when I saw the high temp, i figured I'd have to make it there. It was not over-temp for long. Although thinking back to it, I probably should have left the ignition on so the fans would run, and left the hood up. But, things seem ok.

Maybe. Last week I had an oil change and the oil pan gasket replaced (been menaing to do that for months). Now the 'check oil level' light will come on sometimes right after start up and remain on for a few minutes. I also noticed yesterday that the oil pressure was nearly halfway between the 40 and 120 marks (that'd be 80, i think) for a moment. Today the oil pressure seems to be hanging in the normal neigborhood of about 40 +/- 5.

hmmmm, did I toast the oil level sender when it overheated? dunno, maybe, but why so long to show up?

Oh, and I have two belts, the shorter runs from the crank to the power steering pump and alternator. The longer belt runs the A/C compressor, water pump, and */C. Oh, the mechanic said that the idler pullys sometimes break, cause they are plastic. with 120,000 miles now, should I think about replacing them?

Jason.
