Review on π§ Stant Black Radiator Cap (10330), Enhanced for SEO by Ryan Reiter
This cap has a spring to hold the check valve in place.
This cap has a spring to hold the check valve (small brass washer on the water side of the cap) in the closed position unlike the 10331 Stant cap. While both fit my system, the 10331 didn't hold the pressure until I upgraded to this cap (10330). This issue was pointed out by the reviewer for the 10331 cap. It made my day.
