My 1993 Mercedes 300TE 4Matic project gets cooled down with a new fan clutch. This video should apply to all models that used the m103 engine.

I make the locking tool from a eavestrough nail. Cut off the point and bend at 60 or so degrees so a 3/4" end can slip in the groove on the left side of the timing cover and into the pulley hole as I rotate the pulley with the hex and a wrench until the groove and the pulley hole line up. I don't take off the fan belt, just the fan shroud. Early cars don't have the two piece shroud, a bit less convenient. Put a piece of cardboard between the rad and fan so you don't dent the fins when you wrestle off the fan and clutch.
That was 4 matic, am i right?
Where did you find the pulley holder
You can lock the fan clutch pulley from behind with a tool- I use a short allen/hex key cable/zip-tied onto the end of an extra-long screwdriver. There are extra holes in the fan pulley mount made for this. You don't have to loosen/take the belt off that way. A stubby 1/4" drive allen/hex socket is worth buying and fits in front of the radiator easily- then you can use a long-handled ratchet as the fan bolt is tightened to 40nm. Also, if you open your bonnet/hood to the service position you'll make your life a lot easier 🙂
can you show tighenting and losening the fan belt alot slower…Which bolts are you talking about on the m103 engine ? I can not find it
You had two other option ,replace with a fix fan or electric fan ,but yours save a lot of money neat video ,when I had to replace a fan on my truck due to cracking ,it wasn't that easy or cheap .another great job .
just wondering if you ever did the water pump too ? I am thinking of doing mine myself…they wanted 800.00 US $
and they said 6 hours of the same engine M103…thanks
