C180 Timing Chain Tensioner

[RicardoR]

Hello,

How do I change the timing chain tensioner on a 1996 Mercedes C180?

Hello Ricardo, my I ask why you want to change it

 

[RicardoR]

Because when it is cold, the chain rattles.

when the engine is cold ? or when the weather is cold ?

 

[RicardoR]

When the engine is cold. I've only had the car for 3 weeks, so the weather has always been cold.

Buy a Haynes manual and follow it to the letter, because if you get it wrong you will break the camshaft.

I assume you have done an oil and filter change if one hasn't been done recently, and that the car is very high mileage.

It is more a sign of a worn chain, rather than the tensioner, as other say do change the oil first.

You can check for chain wear just by taking off the rocker cover and lining up the timing marks

Some good advice there Malcolm. We used to do that with the old 308 Merc vans(the one before the first sprinters) they used to suffer from chain stretch, it was never the tensioner. They started to run worse and worse as the valve and pump timing when further out of adjustment, eventually the chain would get slack enough to knock a lump out of the timing casing or jump the sprocket resulting in engine damage.
