Hi,

I did do a search, like a good boy.

I was at a mechanic today, for Crankshaft Damper replacement. He noticed the blade are not turning by hand. He said Fan clutch is bad.

He is not an exclusive MB mechanic, so.. I told him I will get back to him after I consult real MB knowledgable people here.

Here is the fact.

I drove the car to the shop, car was off for 20 minutes, he was taking out the fan shroud, and noticed fan was not spinning freely.

He said fan is on all the time.

1. Should I worry about it?
2. Can this be fixed, I read post about adding Toyota fluid.. or should I just change it.

3.Or is it normal for the fan to turn with the car running.
4. what is the procedure if change needed.

Thanks,

The fan will always turn with the engine, although it might not be fully engaged, depending on the temperature.
When you stop you engine, the fan should continue to turn for a spin or two. Once stopped, it should turn almost freely if you push it with your finger. (A very slight resistance is normal). If it is stucked (jammed) and does not turn by hand, it is shot.
I would not mix Toyota/Mercedes. if it is defective, replace it.
