I am getting ready to winterize 91 PS 190.

On the Ford 351, can you pour RV antifreeze into the block from the upper heater hose (bypassing the thermostat this way)?

Thanks!

not thru the tranny but there us a tranny cooler...its the item at with the arrow in the pic. back flush it and then open the drain hole which is on the engine side of the tranny cooler to let out any sediment...
