cooling system pressure

[dan t.]

1992 350 magnum full closed cooling alpha1 gen II ,during the course of my rebuild this winter I seem to have lost the rad cap for the heat exchanger, anyone know what pressure of cap I should be running. I am thinking 15 lb but would like to know for sure.

I Looked it up for you and the service manual said 14psi.
Also the manual said it will hold approximately 20 US Quartz.
Also said it uses a 143 degree thermostat.
Service manual part number is 90-816463 SERVICE MANUAL #15. Good luck with it.
