There is no drain fitting. You just pull a hose off. If your intent is to get as much of the old coolant out as possible. I would suggest pulling the hose that goes into the water pump off the front of the engine, it is the lowest point in the coolant hoses. To pull that one off, you will probably have to pull the pipe. Or you could pull the muffler, then the side shield off and pull the hose that goes to the water pump off and stick a syphon hose in it. You will have to remove an Oetiker clamp or two... What you are about is not easy and cut and dried.

There is no drain tap or fitting.

Going to the doo micro fiche online is a good place to start. http://fiche.worldofpowersports.com/wps/showmodel.asp?Type=13&make=skidoo&a=921&b=3&c=0&d=-COOLING-SYSTEM

 

Thanks DJM,
I'm going to pull the muffler anyway so I can change oil & adjust the chain tension, so I'll try that route first. Never thought about looking at the micro fiche, good idea!

Pull hose, use shop vac to suck coolant out of system.
