I don,t know what type of auto exp. you have so I will give a very easy description of how to change this belt. It will be a little difficult without the fan removed but the special tool to remove fan is expensive and on the straight 6 it is easir to do than on the v8. It may be easier if you loosen the fan shroud by slideng up the clips on the top to the shrould I don't think you will be able to slide it all the way out but if you can it will be easier. There are 2 types of spring loaded tensioners and they both work the same. one has a 15mm head and the other has an e style head-if you don't have the e style socket try the 12 point closed end of a wrench I beleive a 12mm will work. turn head( i beleive it is to the right) on tens. pulley and slip belt of of one of the top pulleys. Pay close attention to how the belt is routed. It will only go on one way. The trick is getting new belt slipped over the fan in the correct position. I always turn the belt with the smooth side out and start by routing it around the tens. pulley first. then around the crank pulley and down around the a/c comp. up over the p/s pump. then take the other slack coming from crank pulley and route it around water pump pulley and(may or may not have idler pulley) and bring accross to alt and airpump(may or may not have belt driven airpump). On the tenw when you have it loaded you can slip a pin or bolt through the font of the tens. into the grooves in the tens.. housing to keep it from snapping back. If you are replaceing the tens. you will see where this hole is because the new tens. come loaded. You can remove the pulley by turning the bolt to the left and see where this hole is if you can't find it.

How to replace an engine belt on an 1995

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 todisturb theButton 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.
