OK so like you can see from my sig, k4 750,..ive read the service manual bc i noticed some antifreeze coming from the water pump area, after cleaning it and letting it sit i deff. could tell the water pump is leaking antifreeze. So i look in the manual and it says that if the pump is leaking coolant, then i have to look at/replace the mechanical seal and seal washer. Easier said then done, once i pull the pump off it says i need a special tool to get the mechanical seal out..anyone know where i can find this, or would it just be easier to bring the pump into the dealer and say replace this seal???

Thanks in advance..

If you are seeing dried or leaking antifreeze on the outside, it's a leaking hose clamp, not an internal seal. If you see water (milky oil) in the crankcase, then it might be a leaking intermediate seal between the water pump and the oil pump.

thats what i thought too.. but its leaking coolant from the seal on the pump not the hoses..i checked those clamps.. i guess i can take them off and clean them and put them back on and try it but i just figured i would ask on here..

I would wash it off with water, dry it and double check. Maybe you have a leaking gasket, but those hose clamps can fool you. I thought I had a leaking head gasket because dried coolant appeared to be oozing out of the head gasket. Not the case, it just accumulated there from a leaking hose.
