I took a K100 radiator to a shop for pressure testing. I asked the gent who received the radiator what pressure is considered to be the "standard". He said he thought it was around 60-80 psi. Shocked
Is that true? 😕
That figure seems very high to me, but I know little about radiators.

Most caps will release pressure at 12-14psi so even doubling that only makes 28 psi. I certainly would not try my luck past 30psi. I just looked up some pressure testers and most only go as far as 30psi max.
