Works good

Looks and feels high quality, just a little tight on my aluminum radiator.
It really took some force to get the cap to make the last fifth of a turn so that the little ears on the cap were in line with the hose to the overflow tank on my Koyorad aluminum radiator. Neither the stock cap nor my temporary Dormant replacement cap had that issue. Otherwise the cap is pretty nice!

Very nice and decent price!
I ordered this because I needed to replace the radiator on my 2001 SE. I picked an OEM type replacement but with the new radiator, the original cap looked old and worn. I didn’t want some expensive high pressure cap, just a nice, reliable upgrade over the stock item. It’s perfect and looks really nice
