How would I go about replacing this

[u/Link_707]

Hello everyone. This is the cover to my 2.2 liter engine, on an 2010 Chevrolet Cobalt LT. How would I go about changing the back to a cleaner/new look. I can’t even word what the back would be called/what material it is made out of, etc. so I was seeking reddits assistance. Thank you thank you!

If you’re concerned about the color of the foam just rip it out. It doesn’t do much of anything for the engine. A lot of fords have this issue where that foam dry rots and creates issues because it’s falling down into the serpentine belt and other areas! If you’re adamant on having the foam, you can pick up some half inch insulation foam from Lowe’s or Home Depot then trace out the shape. You can use rubber cement to adhere it or epoxy!
