Jeff,
I think common. I got it at a local auto
parts store.

Multiple coolant pressure Caps
Bill:
I've never seen such a radiator cap; are they
common or custom?
I'll look to see if one is available. I
was also thinking about the overflow port and feeding it into my expansion tank
- thanks, I'll seriously consider that as well.

Jeff,
On my radiator, I have a solid cap, no pressure relief. This cap
seals at the top of the radiator neck, not down at the bottom where the
pressure cap seals. That allows the coolant to rise into the overflow neck. The
overflow neck nipple is then plumbed to the bottom of my swirl can and the
swirl can has a pressure relief cap on it. I think 21 lbs on the pressure
relief cap.
This system automatically eliminates air and I periodically check
the swirl can to see if I need to add coolant. I only have to add coolant if I
have had the system apart for maintenance and introduce air.
