2.5L Factory Engine Cover Definitive Thread

[2024ash]

For those who have questions and are considering an engine cover for their hybrid, I wanted to collect all the information in a single thread. This is my first contribution, hope it is helpful!

I was fortunate to find a used junkyard engine cover from a Ford Escape Hybrid for $50 plus shipping. At my request, the yard also pulled the mounting hardware which includes a ball post and a retention bolt/washer/nut.

Ford engine cover 6A949 part number

LX6Z6A949B
LX6E6A949AB

*Or* do an interchange salvage yard search for 2020-2022? Escape Hybrid engine cover

Ball Post part number

6N958 stud is AA5Z6N958A

Retention screw part number (Just need one!):

HT1 stud is W714647S450B (also need H1N nut unsure if included)

My first impression is the engine cover definitively reduces engine noise. The transition to engine power is almost imperceptible and the sound level is noticeably reduced across the rev range. The distinct growl of the Atkinson Cycle, especially in the 20-30% power range, is attenuated but not muted.

The cover is made of urethane or rubber foam and varying thicknesses between 1/2" and 1" . There are four plastic pieces molded in for the mounting points for the posts and the retention screw.

Make sure you firmly tighten the bolt post or when you loosen the nut the post will walk out tear the cover (as you can see below).

There are four mounting points.

The front mounting posts are molded into the intake runners.

You will need the hardware for the rear ball post mount and the rear retaining bolt. Sorry, I didn't grab pics of these installed. They mount here:

And here:

And a video of the engine sound comparison with and without the cover.



Cheers!

Good job with the thread, showing what is all needed.

Your video really does clearly show the difference the engine cover makes!

Cheers,

I am working on a cover of my own design it will be 1/8 thick alum. with slots for air and it will have stand-of brackets that use the 2 threaded holes in back with the 2 ball mount studs in front . It will be a lot like the other brand that is made but for the hybrid. Will take pictures when i get a prototype done

Looks like a great protected area for rodents to nest under.

Looks like a great protected area for rodents to nest under.

That, along with every other nook and cranny in the engine bay, anywhere under or behind the dash, the HVAC filter housing, any cavity with insulation, and the entire interior including where the critical wires run under the rear seat. Rodents love cars.

I hope your post was intended to be constructive but the absence of context is not helpful.

Thanks for doing that Adam. My Ranger had one the factory made and of course it was not on there stock. I did get that one and was wondering about the Maverick as there are the bolt holes on the back of the top of the motor I noticed. Cheap FORD.

My pleasure. It's an easy five minute install, the challenge is finding the cover itself

Edit: forgot to add I agree this was a cheap cost savings move (just like excluding a hoodliner).

Thank you. Your photos and description are very instructional and helpful. (I wish everyone would include photos.)

Yes for all the leg work, I'm planning on putting that on my wish list.
