w220 s500 crankshaft pulley
Hi ,
have an S500 LWB(w220) 1999,
Is there any recall on that model,
(The crankshaft pulley failed on motorway and affected water pump, alternator and power steering and tensioner)
temperature went into red area within 10 seconds, battery not charging, streeing wheel became heavy ....
anyone had such a problem before.
The car is at 78k miles
Any idea of the cost

i think you meant to say the belt tensioner went out. there has not been a recall on these but there has already been several revisions of the belt tensioner. the old ones will freeze up on you without too much notice and will burn the belt off and that is why you noticed the high temp, no power steering etc. i hope you pulled over right away when your temp over heated, otherwise you will be looking at a very expensive repair if your car overheated to a point where your cylinder heads got warped. if you pulled over right away, then you should be fine and will only need to clean up all of the remaining old belt wrapped around the cranshaft pulley and other pulleys and replace the tensioner and a new serpentine belt, i dont recall the exact price on the tensioner. if you are mechanically inclined, you can do this yourself. good luck.

The core of mine fell off. There was a recall so MB covered the expenses on replacing the pulley even if your car is out of warranty.
I wasn't so lucky though. When the core fell off, the crankshaft/pulley or something (advisor never made it clear to me), it managed to drill a hole in the oilpan. Oil pan was roughly $700 plus labor I think.
