Jinshim Posted May 25, 2021 Share Posted May 25, 2021 Hi guys, This question could be really lackluster but in desperate need of confirmation. I have two radiator caps, one on the coolant overflow and one connected from the upper radiator hose. I'm in the market for some shiny new caps, from what I can tell the overflow tank has a cap rating of 13psi, but the other has no other signs other than do not open when hot. Are both radiator caps pressurised, and would everything be Ok if they got upped to 19 psi caps. I'm upgrading to silicone hoses all round soon but wasn't sure whats safe!

Willsy1980 Posted May 25, 2021 Share Posted May 25, 2021 Think only the expansion tank is pressurised, I changed mine for the Nismo one and added a cover to the standard one on the rad Both from Torqen 2 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 25, 2021 Share Posted May 25, 2021 Stay at the recommended psi. As said ^^^ only one cap is pressurised. 1 Quote Link to comment Share on other sites More sharing options...

Willsy1980 Posted May 26, 2021 Share Posted May 26, 2021 No worries bud, they do finish things off nice. Cover is from a member trader @RDON he may have 1 or 2 left. I know stock was low. 1 Quote Link to comment Share on other sites More sharing options...
