Anyone running without engine cover

[TC]

Is the 5.7 engine cover important for performance? Or can you run without? Just curious if running without will keep engine temps down.

Not important took it off all my rams its honestly just for looks.

 

[mrack]

Not necessary at all, they stopped putting it on classics a few years ago

My '21 never came with the cover.

My '07 Tundra had one and all it did was provide shelter for rodents to build their houses.

Took mine off to do my plugs and coils. Never put it back on. It's been fine without it.

Bought new 2024 classic, did not come with one. Have one from a different truck. Putting it on as I like it.

I have two of them tossed on a shelf in the shop. They work great up there.

You really only care about covers if an engine is air cooled. Removing covers can mess with how the air flows around the cooling fins.

They’re meant for owners who leave their hood open in direct SUNLIGHT to protect engine components from UV radiation.

They also serve a dual function as a nesting cover for rodents seeking shelter from the elements on cold nights.

I noticed mine has a nice section chewed away too. Little ******* bedded into the passenger side framing too. I'm going to just remove it and see how things run. Unlikely there will be any differnce other than maybe hearing the intake a bit more.

Maybe they force airflow up and over to the backside?

I took mine off to save weight and get better gas mileage

They're decorative on these trucks. There's really no benefit to having air flow on a liquid cooled engine. The only air flow that's needed is through the radiator. I would even argue that covers on a liquid cooled engine would help to hold heat in if anything.

Toss a couple of pieces of Tomcat under the hood.

Maybe limits a bit of throttle noise? I'm taking mine off all the same. Looks better too.

Maybe, but I doubt it would be enough to notice if so. I don't have a 4th gen anymore to test that, but on our 5th gen I didn't notice any difference in throttle "noise" when we were running the truck without an engine cover.

Removed mine a while ago, because it chaffed the Heater Core lines, and cause a leak.
Left it off, and Air Inlet Temp dropped 10 degrees, do get about 0.2mpg better. Because of lower AIT.
No noticeable change in cabin noise.

I took mine off and sold it to a Classic owner for gas ️ money

 

[Marine Les]

I removed the cover on my 2018 3.6 Pentastar because it made changing the oil filter less of a problem. No issues.

Mine is off for better aerodynamics....under the hood

But seriously, it keeps heat in, fosters critters to migrate there and call your engine their home, and to me personally, it looks out of place.

I took the cover off my 19' the day I bought it new. My new Warlock didn't come with one, and I'm happy about it because it too would have been a shelf warmer.
