I have been through this entire thread. Is there any hard data for system pressure when the vehicle is in use?
I went with the Volvo bottle and cap, twice. The first go-round, I picked a junkyard bottle with a green cap. After two years of thermal cycles, the bottle deformed enough to leak. This time, I incorporated the steel bracket used to mount the Volvo bottles. With the black cap, everything "looks" OK. With the green cap, the bottle looks bloated at the ends.
The reason for asking is that the black and green caps are rated approximately 11 PSI and 22 PSI respectively. I was told the RENIX cap relieves pressure at 14 PSI (Can anyone confirm this?).
More than anything else, I am concerned about over pressuring my heater core.
My bastardized mounting system.
Just did some number crunching and the vapor pressure of pure water at 230 F (110 C) is 21.7 psi or 150 KPA!!!!

12-15psi according to my 88 FSM. Confirmed.
I'm still using the Quadratec bottle I got years ago. I bought a cap at my local Jeep dealer and it's held up well. I also have a new spare bottle as well as a Volvo one I picked at a JY (no cap).
I've been doing fairly regular flushes and check my coolant level often. My bypass valve is looking pretty ratty these days so I may have to splurge and replace it soon.
Looks unused like its been in a museum LOL.
Funny, I checked the beginning of this thread and see my post from 2008. Yes, that's the same tank and cap.
