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
