Re: Which Antifreeze to use ?
Terry, I just bought a Ron Davis aluminum radiator and asked them the same question about which antifreeze to use. They said the green is fine as long as you use distilled water.
There's been alot of discussion here about DexCool and it sounds like it needs to used in a closed loop system like the newer cars have. Not the ones that are open to atmosphere like the 1st gens are.
I personnelly ran the Zerex G-05 in my aluminum radiator, aluminum head engine going by the reccommendations here on this site. (I believe this is a yellow color too). This was before talking to a Ron Davis rep.
