Quick Rad. Cap Question
What pressure should a cap be in a stock four core radiator? Think the one I got on there now is 16lbs but it was just what I had laying around and didn't come with the unit. Thanks a lot

I think 13-16 lbs is what factory calls for.

1971 Chev Truck Service manual states "All truck cooling systems are pressurized with a 15 lb. pressure cap which permits safe engine operation..........."
