I removed the plastic engine cover from my 2008 Ecotec for the first time the other night. I noticed it has a foam layer under the plastic. I'm sure Chevy designed this to further insulate the driver from any engine noise.

But doesn't this foam and plastic cover act as a "blanket" too? In winter, I suppose this would be a good thing, to hold in heat and insulate from extreme cold. But in summer, isn't it a bad idea to have a big blanket over your engine? There is already a blanket of insulation under the hood, right?

Any thoughts?

Anyone take their cover off and leave it off?

Thanks.

I ran my cobalt without the cover in both summer(+30 celsius), and winter(-30 celsius), and it was fine

I always thought it was mostly for aesthetic reasons.

 

[cobaltkrazy]

yeah, pretty much

Looks only, no real purpose.

Yeah a good portion of balt owners took that cover off the first day. Its useless other than looks and slightly dulling engine noise. I've had mine off for about 2 years now.

I want to leave it off but not until my engine is decently presentable. You know polished and shiney! Until then, big black rectangle it is.

Hehe, my engine had all kinds of funky weird stains/marks on the metal and stuff but I still opted to go without the cover...

I have mine still but not on just sitting in the garage lol.

Took mine off back when I had my LS, only difference it made was cool the engine like 2 degrees compared to before. I think it ran at like 189* and than after it was 187*.

Weight reduction! lol

I took mine off because it kept popping the oil cap neck out of the top of the motor. I agree with everyone else, its just a visual thing, serves no other purpose.
