Thanks for your fast reply.
No I do not service this car myself.

I drive 1981 300D and have nothing to do with my wife's car.
We always take it to mercedes work shop on time. But it is Sunday here in Sydney and my wife has missed on going to church because of that broken belt.
I needed a source of info to be able to get more involved in servicing this car.
Regards
Fitian
