Don't wanna blow coolant system! 23 psi for Pressure Leak Test?
I don't want to blow the coolant system! Is much higher 23 psi rating true?
Please help! My pressure leak testing is delayed only because I found differing PSI numbers for the radiator SYSTEM. I will be using the Powerbuilt tester loaned from Autozone. I found the following numbers from various sources below: ...Leakage Test Pressure 157 kPa (23 psi), Cap Relief Pressure 81-109 kPa (11.8-15.8 psi) from sources: +Villager [Chilton online via public library] +Quest: [Chilton online via public library: can't seem to find spec] +Quest: [FSM [factory service manual] ...16 psi??? +Haynes book for Quest/Villager, which didn't see mention of 23 psi: page/section 3-1 "radiator pressure CAP rating" = 11.8-15.8 psi page/section 1-2 "radiator CAP pressure rating" = 16 psi Printed psi on cap itself: +current on van: no spec. I don't know if OEM or 3rd party +Oreilly, Autozone: 13 psi +dealer: cap no longer available and no spec |
Ohhhh man, that is not good, not at all. I mean, in case you got different PSI numbers for the radiator SYSTEM, it is really really bad! My dad's coolant system was blown because of that. Did you actually fix that?! The PSI numbers do not have to be different, a small difference is ok, it can be tolerated, but in case it is bigger, you are in a big trouble man. You can read some useful information about the coolant system in here https://cararac.com/coolant/, as I have also found some useful info for myself in there.
