Default Re: Block drain for 8RT

I did it mostly to be able to completely drain and change out the anti-freeze every couple of years. I will say that it is best done with the eng out of the vehicle. may not be possible in the vehicle
Thanks, Alaska Jim for the input. I will put it in the brain housing group. Mine is a '50 merc block with BA heads. Don't know how you have a lot a cruising time up in the tundra country! But I know any time is great with a flattie!
