603 Fan Clutch Removal / Installation
My fan clutch is not working. I think it needs new fluid and i have some.
It is supposed to be an "easy" job, but only if you have the "right" tools. After searching the site, I find that the right tools are a stubby allen socket and a water pump pulley holding tool (603 589 00 40 00). The socket is not expensive, but the pulley holding tool is. I have tried to hold the pulley by hand while turning the allen bolt, and I can't. I installed the fan clutch myself when I replaced the water pump, but I did it with the water pump out of the car and I used a torque wrench. My questions are: 1. Does anybody have a used pulley holding tool (603 589 00 40 00) that they don't use want to sell / donate / rent. There are probably a lot of retired mechanics that have one. 2. Is there an alternative way to hold the pulley that does not risk damage? 3. Is there a generic tool that works that doesn't cost a bunch? 4. Does anyone sell this tool at a deep discount? |
I had a buddy hold the belt around the pulley while I loosened the bolt with a right angle allen key. I didn't remove the radiator. Fan shroud came out with the fan.

Anybody near Charlottesville VA have the tools?
Since I don't have a buddy to hold the belt. Maybe somebody near Charlottesville VA has a tool I can borrow?
I might let you use my fuel injector balancer! |
harbor freight has large strap wrench for 10.00 works great.

Strap wrench works great, so does an old belt and pair of vice-grips.

I have the Harbor Freight tool and also have used Vice-Grips(R) and the serpentine belt to hold the pulley. Both work. I use a standard Allen wrench in the center bolt and a short length of steel pipe for leverage. The real key to this job is the two-piece shroud to which my engine was updated. It makes access so much easier. I don't know how it is for an SD.

To hold water pump. Look for a hole in the water pump hub. Insert butt end of a drill bit in it, rotate until it locks. Used this method to R&R mercedes pump. Do not know if all pumps have the hole.
