Title: coolent pressure DD6V71

I've decided to eliminate the existing pressure relief doohickey on the expansion tank on my 79 MCI 6V71. Not the button next to the filler cap but the round thing on the other side of the tank. I'm modifing the existing fill cap and adding a standard automotive radiator cap. I cannot find what the system pressure should be? Anybody know what it should be or where to look? Its not in the service manual.

Don't know if it helps but on my 8V71, the manual says 7 lbs. pressure.

Happy Trails,

All replies are greatly appreciated. I do not understand why my manual makes no mention of it?
