Thanks everyone! She's purring like a kitten again.
I for one, have never seen belts so destroyed on a car that barely exhibited any symptoms... Since power steering and the waterpump are on the same belt, I'm curious if it was slipping on the water pump too or if the steering pump was the most prone to slippage. Car never overheated, so I guess it wasn't enough to mean anything.
Even more surprising is that the A/C worked! The A/C belt looked worse than anything else.
I drove to Racing Dynamics this morning and met with the owner. We picked up brand new belts and fluid and drove back to RD.
Man... they have some GREAT stuff in there. And some exciting stuff in development. Can't wait to try their downpipes on the F10.
When the mechanic removed the old belt he noticed that it was 7mm shorter than it was supposed to be. This could explain why it failed prematurely. I guess 44K isn't that bad given this situation. Luckily, as bad as the belts looked, nothing else was damaged.. They can take things out if they snap off hard.
The pentosin in the reservoir actually looked brand new, so I left that for now. But going to change it in the next 5K when I do the front and rear rotors, pads, and 295/30/19 tires.
