350SDL Serpentine Belt Tensioner Shock - How Difficult Is It To Replace?

Is it an easy DIY job to replace the shock?

Can someone here give me the procedure or point me to it?

Thank you.

Yes, more or less.

I'm going from memory because I don't have the car in front of me and the FSM is limited on the DIY.

You'll need to remove the fan shroud and then the fan which is secured with 3 or 4 allen bolts. Should you choose to make life easier you can remove the radiator. This will make getting the fan on and off much easier. The downside of removing the radiator is tranny fluid loss and coolant loss. I'd probably do it since rubbing up and down the radiator is not so much fun.

Once that's done remove the bolt that is connected commonly to spring and shock pivot on top, then bolt holding shock to lower portion of tensioner.

Note that the shock is VERY slow to compress. To get the new one in it will have to be fully compressed (it took me a little fighting with the shock to figure out I was going to lose unless I was patient).

Put everything back together and check for any problems.

Do you have the FSM? Kinda critical for at least the diagram, less so for the 'how to'

I was able to replace it in a 300SDL without removing the fan or shroud. I don't think I even took off the belt. IIRC, disconnect the top attachment of the shock, pop the front cover off the tensioning pulley, remove the tensioning pulley (6mm or 8mm hex), position the fan so you can get a 12mm hex on the tensioner bolt. To work within the clearance and what McGuyver items I had on hand, I took a bolt that takes a 12mm socket and jammed a couple of nuts on the shank. I put the tool into the tensioner arm bolt and turned the nuts to loosen/tighten the tensioner arm bolt.

Thumbs up

Yes, it's easy. I really enjoy the single belt of the 603.
