Thanks Caferacerx for your input, your last sentence is why I'm asking these questions.Mine pukes cold ,this is really no problem because I don't overheat and Stroker I think your comprehension skills might be lacking,the question asked was not about the catch can and as far as reading more to learn I think thats why I come here to FABO to read , learn and ask questions.

No, I understood fine. No need to take jabs. Nobody did that to you. All I have offered is literal advice. So yes, if you're talking about the cooling system, the overflow can is a part of it and you are talking about that. Contrary to popular belief, the cooling system is not under pressure the entire time it is hot. That is why it has a catch can and a presusre valve on the cap. However, probably well over 80% of the time the cooling system is hot, it is under pressure. When I said you should read up on it, I was completely serious. Nothing was meant malicious. No need to get defensive. There's a first time for everybody to learn about somethin.
