Not much to say, it just works
It’s an OEM part for my Chevy Impala 2006 3.5L by GM. It works just fine, it keeps my cooling system pressurized properly, I can feel the hoses get tight. No leaks. Ops check good at this time.

I was losing heat inside my van when I was not moving. It turns out that the radiator cap was not holding pressure in the heating/cooling system, allowing air to pass through the heater without being heated. I replaced the cap with this OEM model and things have been fine ever since. Price was way less than from the dealer and shipping was quicker than advertised.
