Great replacement cap

This cap is a perfect replacement for the OEM cap. It was purchased for a 2008 Chevrolet Malibu, 4cyl engine. I misplaced the original (don't ask!) and needed a replacement. The local auto parts store wanted triple the cost of this cap. What more can I say? This keeps your coolant fluid contained where it should be, if all else is working well. It's as reliable as the OEM cap. Got it in two days, very fast delivery. Overall highly recommended if you can wait 2 days and want as close to OEM cap as possible.

Item arrived as expected, unfortunately it was broken in transit and needed to be replaced. Walmart took care of it and shipped out a brand new one immediately.

I trust Dorman quality, and it fits %26 performs like the factory original. Surprisingly quick delivery. Walmart has become my automotive parts supplier. Photo would not load, but it looks like OEM.
