  2. supraguy, in a nutshell ...NO.......the engine has to be super hot so the tstat is open, and that allows the block water out,not in, and incoming water to be sucked in thru the circulating pump. And then it is only diluting the water in the block. Untill the tstat opens all the intake water /Afreeze will flow right out thru the muffler and exhaust.....There are block drain plugs on these engines for a reason.....USE THEM.....then if you want to be anal , fill the block up thru the top of the j hose by pulling it off the tstat housing...... you have winterized your impeller and exhaust manifolds already tho so you wouldn't have to drain them

    Howdy Doc, Hope you can answer my question:
    I recently winterized my Supra 351 Windsor and this is how I was told to do it for below zero storage. I started her up and poured into the intake hose over three gallons of RV anti-freeze until the exhaust came out solid pink. I am told
    that this insures that the fluid will displace any water in the engine block, water pump, hoses etc etc etc.
    Is this info correct? Did I get good advice?
    Thank you, supraguy
