Mayf;

Maybe I'm wrong but I think that any pressure cap has a vacuum relief valve
built- in. I have never bought one that made any reference to this but it
seems logical-- just one of those unsung features.

Hmmmm, quite frankly I hadn't even thought about a coolant recovery 
system. I like that even better than a throw away system. I'll go look 
at some tomorrow at autozone or carquest or checkers or whatever it is 
way uptown in Pahrump. Just for drill though, doesn't a coolant recovery 
system need a pressure cap on the radiator that  can let the expelled 
coolant back into the system? I run a pretty good pressure cap as I 
recall. My coolant system is a scirroco radiator buried in a water tank. 
The water tank is vented overboard but the engine coolant was going to a 
big holding tank when it over flowed.

tank system with no radiator. My coupe has only a radiator and an electric
pump. I do have a catch bottle with that one. It goes in the cap with the
hose extending to the bottom. There is a 1/8" hole in the top to relieve
pressure. When cooling, it sucks the expanded coolant back in. All kind are
available at McMaster-Carr: square, rectangle, round, etc...Mounts/brackets
are pretty east to make....Good Luck
