What is the correct coolant/mixture for both warm and cold climate operation of a stock 53 239 V8. The car is in coastal New Hampshire. It will probably be in heated storage this winter, but just in case I want to be prepared. Thanks!

30 yrs- all of my other cars are new and usually maintained by the dealers. In the 60's in Pa we would only use a few quarts of antifreez in the winter only, plain water in the summer. I just don't want to screw up the system in my 53 by using too much or the wrong type of antifreeze

It's a balance between having enough antifreeze to keep the engine from freezing in the winter and as little as possible to improve cooling in the summer (since water cools better than antifreeze). The balance I found best for where I live in Utah is two gallons of Sierra propylene glycol antifreeze (since it cools better than ethylene glycol) and three gallons of water. That combination protects down to 5°, which is colder than I've ever parked outside overnight at a motel (I keep mine in an insulated garage too). Hope this helps. P.S. Prestone has just started making a non-toxic propylene glycol antifreeze too.

Follow the directions on the bottle to protect your engine for the coldest temperature it will see. Protection to -20F seems to appropriate for your area.

TomO has said it best. As an old timer told me "When all else fails, follow the directions". I lived in NH for a few years and protected my '41 to -20. If you feel you are having cooling problems in the summer change to water. I like to use distilled. Also, I don't know your heated garage situation but I remember reading something on another thread that I never thought of. The guy had a heated garage so didn't bother with anti-freeze. His heat went out and his engine froze up. Better safe than Oh so sorry.

The above are correct. Don't take a chance. If the local electric service went out for very long you could experience damage (been there). I'm in upstate NY and use 50/50 mix to get protection down to minus 20 or so. Mix per container.

Tagging on to this discussion, much is made of the additional cooling benefits of Sierra propylene glycol versus Prestone ethylene glycol. From a purely technical perspective understandably so. Just curious as to whether anyone has empirical data/knowledge/experience with your personal V8s as to what the actual improvement and/or reduction in temperature may be realized by using the Sierra product in our engines. Thanks in advance -

I have not noticed a significant difference in temperature control between Sierra and Prestone, except when the Prestone foamed and ran out the overflow. The Sierra doesn't foam as easily as the Sierra. The big advantage of Sierra is that if you have a leak into the combustion chamber or oil pan, it will not destroy your engine like Prestone.

The only reason I use Sierra is that if it leaks in the garage and my dog drinks it, it could kill her! If it were not for that I wouldn't spend the extra money for it. And I wouldn't use distilled water either.
