E320 Serpentine Belt Replacement Directions

I have two Mercedes - one is 2000 E320 Wagon; other is 1999 E320 Sedan.

I replaced the serpentine belt on my 2000 Wagon today at 92,000 miles. I found that the Motorcraft JK6-947 could be purchased on Ebay for $12.99 plus $6.20 shipping. The old belt was a Goodyear Gatorback 4060940. My 1999 sedan has a Mercedes Benz 011 997 97 92 6K2390 EM7117 Gates belt made in Spain.

Here are the details of replacing the belt.

On the 2000 E320, a 17 mm bolt just under the belt going to the tension pulley will release the belt tension when turned counterclockwise. Removal of the belt was easy after using a 17 mm deep socket wrench similar to a spark plug socket. I made turning the bolt very easy by slipping a 4' pipe over the socket wrench handle. It is advisable to put the new belt LAST on the idler pulley that contacts the belt only on the smooth side.

You do not need to disturb the Button Torx bolt in the center of the tension pully.

The 1999 E320 uses a 15 mm bolt in the CENTER of the tension pulley. Otherwise the installation is the same as the 2000 E320.

Hope this helps.

Hi, CT, and welcome to the forum.

We'll have a mod move this thread over to the 210 forum, since it is information specific to the 210 platform.

Good points all around, the only thing I think I would add as a suggestion is that for the first timer, take a sheet of paper and map your pulleys, then the belt routing. That way if you get confused you've got an "assistant".

Thanks for the post!

Take care and enjoy the ride,

Well... our ML has exactly the same engine, the same belt and exactly the same routing.
Those things are important as you can read about my experience with Peep-Boys
