Always use a 50/50 mix of antifreeze and water year round. Never ever run straight water!! HTH. -Jim

Might not have one. For some years, GM thought that saving a buck on each car would add to their bottom line. They found out that it wasn't a good idea and started putting them back in a few years later. Like "Kelly" said, if you can't find the valve, jus pull off the lower radiator hose to drain the system.
