Cooling system Maintenance (LDS465-1A)

[kaiser2help]

Can anyone tell me a good technique on draining the coolant from my multi-fuel? I am not sure how many drains are on the block and perhaps anywere else. I found the obvious ones on the bottom of the radiator and on the left side of the block ( on the turbo side). But if there are others I cannot find them. Thanks for the help.

Its a process, Cranetruck wrote an excellent article on this. Basically drain it out (you'll only get 5 gallons) and refill with distilled water. Warm the engine up to open thermostate and drain again, repeat this process 4 times. On the fifth fill, use 4 gals antifreeze and 1 gal. distilled water. Also add SCA or DCA at this time.

Adding a coolant filter is also a great idea. Do a search here on the deuce forum for directions and pics.

Good luck.

To drain it totally, I would pull the radiator and the thermostat housing. Then run pressurized air through the hole where the thermostat was. It will not get it ALL out, but most of it. Are you asking for a reason? Maybe replacing all the hoses? Just want to put new coolant in?

If it works, this is a link to the article:

Thanks guys. Gimpy I had to replace my radiator so I just figured that I would like to get a good flush out.

Yep it works Bjorn, just completed the 109 coolant change, ready to do the M35. Have coolant filters for both as well. I think the coolant filters and the oil filter adapters from John Tennis are a must for any deuce I own.
