Timing belt

[oilyfingers]

Hi, mother-in-law has just had her A class serviced & new r pads by local garage as all i used to do was reset service indicator & change oil/filters. He has recommended timing belt change as he claims its got cracks in it. I,ve changed belts on peugeots, vauxhalls & landrover but not on mercs. How difficult is it as i think she,s going to approach me to do it? I originally thought these were chain?

Timing is by chain but there is a poly 'V' belt that drives the ancillaries.

So i was right then. How hard is the belt to change as i know some motors are awkward to re-tension belt?

You need to release the auto-tensioner but I'm not clued up on the details. I'm sure someone will be along to fill in the gaps!

Releasing the tensioner is easy. Wack a socket on it, turn anti clockwise, remove old belt, put new belt its place then release the bolt.

Its spring loaded, obvious when you do it.

Thanks guys, i,ll look into getting a belt for this then.

Access is the problem here - it can only be done from beneath, and is a bit of a pig even then.

Good luck with the socket, DIY these are a pain.

Oh crap, didnt see it was an A class!

I want to buy 1999 300E Turbo Diesel with 265k miles on it.
The dealer says there are a few types of warranty plan. i.e. engine, tranny, electrical, etc. Based on this model and mileage, what kind of warranty is recommended?

At what mileage should I change the timing belt/chain for this model?

Thanks,
