When to replace a Mercedes timing belt

Do you have one of the aforementioned Mercedes models with a timing belt? Then remember to replace the belt on time. If the belt wears out and snaps, you are further from home, so always replace the belt on time! Check the service booklet of your Mercedes to see if you can find information about the last replacement date. If this is not filled in, see if there is a sticker under the bonnet showing the last date or mileage at which the timing belt was last replaced.

If you do not know when the belt was last replaced and cannot find a sticker, it is wise to have a garage check if the belt needs replacing.

When to replace Mercedes timing chain

Good news for Mercedes drivers who have a timing chain. The timing chain is maintenance-free, while the timing belt has a replacement interval. If you want to be sure, we always recommend consulting the owner's manual, which will tell you whether your car has a timing belt or a timing chain.

Is a timing chain better?

That a distribution chain lasts a lot longer than a belt should be clear, but a chain can also cause problems. In general people say that a chain can last up to 300,000 km but in practice it can happen that the chain stretches which can cause a rattling noise. So it is important to have the car checked regularly and to inspect the chain properly during the maintenance to prevent possible problems and damage.
