So my 2021 Trailhawk did not come with a cover. when contacting jeep and researching they say it requires


68411184AB - engine cover
68228213AA - ball joint
06512725AA - bolt

no where does it allow the spacer

i had to go to the 2019 to get the space Engine Identification, Service Engines & Engine Service Kits for 2019 Jeep Renegade | Mopar Estores

68411188AA - spacer

also 68491180AA is the engine cover.

if you go by the diagrams the cover they say fits the 2021 is the 2.4l cover

so at the factory if they are telling them to install the 184ab cover which is not compatable. they left it off since it will never fit. yet werent smart enough to understand the 180aa is the correct one

they only did this for the 2021 getting it mixed up

am i right? can someone verify the part number on their 13l turbo engine cover?



correct cover

Well, first, we kept saying that the 2021 Trailhawk with the 1.3T engine doesn't have an engine cover -- though your dealer told you yours should have. And even though earlier Trailhawks with that engine apparently did.

Yet, as you show, there is an engine cover in the parts catalog for 2021.

Maybe they slightly redesigned the top of the engine for 2021, necessitating (theoretically) a different-shape cover...?

Ya gotta do what ya gotta do... :) But, as the diagrams show, it's "Cosmetic."

So, did you finally get it to fit your 2021?

If you look up the engine cover in any of the Mopar online stores you’ll see “Used Up To 08/02/2019” next to item description. That’s probably the release date of the 2020 models. I think they just deleted it to save money. The price of those things is absurd. $97 to $150 for a piece of plastic trim is over the top.

Where did you hear that? It would be odd that the engine cover was the only part that wasn't available.

I'd say it was more likely to save a couple bucks; since the engine cover is "cosmetic" only.
Except they aren't. I mean they are mechanically meaningless, but they provide noise abatement. They are part of the NVH management in modern cars.

NVH? :unsure: Oh, Noise, Vibration, and Harshness. OK, maybe. Though I can't really see how a cover over just the engine would abate total engine noise. Maybe a bit, from the valves...?

In any case, I don't find the noise from my 1.3T engine to be at all excessive without the engine cover.

It does look nice, though... :)

Yeah pretty much to cut back on valve train noise, especially with the advent of variable valve timing. The multi-air is exceptionally loud, but most of them aren't quieter than an old school valve train. But they abate noise by the sound hitting them and they vibrate. That's energy taken out of the sound wave.

A lot of NVH stuff is inches adding up to yards.

So other than the space post. none of the attachment points are threaded or have filler threads.

I had to thread the 2 knob spots to get them to attach. now i need to find a plug for the second threaded bolt so it will attach

Which, I hate to say it, seems to indicate that the 2021 1.3T engine wasn't supposed to have the engine cover after all.

Whether it's a good idea or not....

when you say "knob," do you mean Item #3? And the "threaded bolt" is Item #5?

What are you threading them into?

spacer is 5, bolt is 4 , and knobs are 3

i cant find the part number for the plastic cover you have to insert the threaded m6 adapter in . which should tell you what the used as far as a part number but i used a rivot i got off amazon. the knurled plugs will work if you get the right size. just have to insert them. which the factory did not
