Well guys,

I finally did it with the help of my father-in-law. Hopefully the following will clear up the confusion and help others in the future

STEP ONE Remove the fan shroud. It can be done by first lifting up from the top to releas the lower clips. Then from under the car push the lower portion of the shroud forward to the radiator and in front of the fan blades. Next, pull from the top rotating the fan blades out of the way.

STEP TWO: Remove the fan. This is accomplished by removing the (3) 5mm bolts holding the fan to the fan clutch. A mirror makes locating the bolts easier.

STEP THREE: With the fan off the clutch, remove the 8mm bolt holding the clutch to the pulley. For this job I needed to manufacture two tools.

Picture one below is the tool I made to replace MB P/N is 603 589 00 40 00 mentioned by Dr. Diesel. This part was $83 from the dealer and required waiting 3-8 weeks to receive. All it is is a piece of flat steel from Home Depot with two stagered 1/4 inch nut and bolt arrangments. Use steel bolts and cover them with 1/4 inch rubber tubing to protect the pulley. Face them one way for removing the pulley and the other for replacing it. Total cost was about $6.

The second part was a the allen wrench to remove the pulley bolt. I simply started with a standard 8mm allen wrench and cut off one inch with a hack saw made for cutting through hard steel. This gave me enough clearence to remove the bolt without running into the radiator.

STEP FOUR: Remove the pulley. This is accomplished by removing the four bolts hoding the pulley tp the backing plate.

STEP FIVE: Remove tensioner and replace belt.

There you have it. If there are any questions, I will do my best. Thanks
