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!
Thanks
Nick
