While the description does not say that the gasket is included, the picture is misleading. I had to purchase the gasket locally. Customer support wasn’t very helpful. It is rated at OEM specs, but it didn’t fix a lowered temperature gauge reading for me. I guess I’ll see if it fixes my issue when I need the heat in the winter.
