W208 clk430 serpentine belt replacement
 

Hello everyone.

I need with instructions on how to replace the serpentine belt on my 2001 clk430. i have already purchased the belt from the dealer and will like to do it myself if possible.
Thanks and have a nice drive!:cool:

Depending if you have the new or old style tensioner, you'll need an E10 or a 17mm socket to release tension on the belt. Removing the fan is not necessary, but it will make the job easier. You'll need a 36mm wrench on the fan clutch while counterholding the pulley. Once the fan is off and you have released tension on the belt you can use a 4-5mm diameter pin or similar to hold the tensioner in the released position. There's a notch on the lower right side of the tensioner.
