- We investigate to see if Engine Covers serve any other purposes, besides cleaning up the look of the engine bay. We review sources on their take of the trend on use of engine covers made by the manufacturers and we examine engine cover designs from several vehicles, so come equipped and some do not.

Hey Anthony, I appreciate you digging into this topic more. If people care about noise then keeping it on makes sense. I'd rather hear the engine a little more so if something is a-miss I might detect it sooner. As for not removing the hood blanket, I don't know if I buy the protect paint from heat argument. Removing the engine cover should allow more heat to escape the engine. But if its then trapped by the hood blanket, it still won't be ideal. Getting rid of the blanket (especially if it's thick) should allow more air circulation throughout the engine bay which will reduce heat especially when its driving and making heat (each design will impact this effect of couse). I'm in Arizona and even if it isn't running, if you park in the sun the hood is taking in a hideous amount of heat, burn your hand hot. I don't see many hood paint issues except on old cars that (you can tell) weren't well cared for overall. Its an interesting discussion.
The hood blanket me be more for noise isolation. I've discussed it with my Dad and other people and everyone has their conclusions. If you're really trying to let heat escape you need vents or heat extractors.
@@AnthonyJ350 I would like a heat extractor mod
I know you didn't recommend removing the hood liner, but let me reiterate to anyone thinking about doing so: DON'T. Most hood liners are flame retardant and are meant to be quickly pulled off to throw over the engine block in case of fire. They're essentially fire blankets. Like you said, they do well to dissipate heat from scoring your hood, and on vehicles with thin hood paint (Mopar/Mitsubishi, Hyundai/Kia, and Toyota) they'll go a long way toward saving the paint.
But why don't all cars come with one?
And then you let your car bake in the Sun and your hood gets way hotter than it ever gets during operation. If your engine gets hot enough to burn your hood's paint, any plastic intakes, plugs, fuel rail clips etc... will be a puddle on your skidplate.
That's a myth lol... the only thing that a hood liner for is sound deadening.
I like to see the motor and I also like hearing the motor. Especially if something sounds wrong
Great point, being able to hear if something is amiss.
I have a 2018 Jeep Compass should I leave the engine cover on
@@Yankeefann yeah and while you are at it remove your air box and filter so you can hear the intake better.
@@motor_citymuscle288 okay... I don’t need your sarcasm suppose I was someone that didn’t know I needed those things you my friend are an assjole
@@Yankeefann ha I thought you were trolling me by saying you had a Jeep Compass.
I have the same Sienna I've been taking the engine cover off once springtime comes around, these engines aren't known for cooling problems but the way this one's shoehorned into the Sienna I figure it can help all the cooling it can get
I'd just leave it off the whole time
In cold weather it helps the engine heat up faster.
I happen to know these siennas in particular take forever to warm up
Have you actually verified this? Because Mustangs have engine covers but F150s don't.
Wouldn't a 4X4 truck benefit more from the cover than a Muscle car in the winter if that was the case?
Sweet follow up video.
I will try life without my engine cover and monitor it. Definitely mines only benifit is noise as you mentioned(and looks🙄).
I think I could also re-route the wires add some more split loom to make it look better without it👍
Thanks, let us know if you notice anything different.
So far so good. Definetly noticing More valve train noise at idle but not overwhelming at all. 2 days over 35degree celsius so far...
@@CovenantAgentLazarus Do you have an explanation for this?
He probably would've been thinking about the cables melting or causing a short circuit somewhere.
@@alibibax Why would you move cables from where the factory clips are placed if there isn't an issue?
At the beginning of the video when you mention the heyday of engine beauty. Another point to think about is that the vehicles back in the day were RWD, and you can see more of the components because of it and it looks so much cleaner. The transverse mounted engine is the reason those ugly plastic covers exist.
Good point!
i can say the cover on my avalon really helps cut down the injector noise. other than that every other engine cover seems to do nothing.
i just pull it off and clean under it every oil change and check for mice... never had a mouse chew on of them up, they typically go for the firewall insulation and into the cabin filter area
I show a variety of covers in this video th-cam.com/video/o5exAlHJQvE/w-d-xo.html
I removed my engine cover from my 2008 Dodge Caliber SRT4, it was horrible I once checked my oil and I wasn't able to put my dipstick back in cuz the cover was on my way.
And I had to unscrew my intake since it goes over the engine.
Also now it cooldowns faster and I can access to my spark plugs too.
I have near future plan to swap my valve cover to Evo10 valve cover, cuz it looks way better and it's made of metal, my current valve cover is made of plastic.
Thanks so much for sharing your experience!
Sales gimmick is true. I'm actually considering coating my plenum with high temp engine enamel. Dust will find a way to travel when it goes through the bumper/ grill. I can see why the zed stays in your garage. I would too
Nice! Let me know how it turns out!
My 97 camry hood liner was sagging and later caught on fire, didn't kill the car but its a good idea to check that out. I believe older car's hood liners weren't fireproof.
Thanks for sharing your experience.
Engine is beautiful by it self, after a few years the plastic connector for sparkplug crack Toyota Yaris.
I agree
They all do at some point
I don't mind engine covers, at least smaller ones like on my accord. But I HATE those covers like the ones on some Acuras and Lexus's that surround the perimeter of the engine bay. They just make the engine bay look stupid imo.
I ageee, we show covers that make sense and ones that don't in the second half of the video.
You can run it without hood😝
Oh yeah? Well maybe YOU look stupid! (imo)
I drove my car from CA to NYC. I removed my engine cover one day to perform some basic maintenance. Long and behold there was a rodent nest! I got lucky no damage was done.
Engine covers are useless!!!
Yup, the just mask the noise of modern fuel injection systems. And make everything super hot.
They collect the rat piss and poop from going into your engine bay :D
Who does?
Engine cover is excellent on subzero temperature. It's good for fast ignition of engine on cold weather.
Thanks for your input!
I live in Canada so I may keep it on my daily lol
i think companies should focus on covering the wires than the engine and engine should dissipate heat better not contain heat
I totally agree. Layout the wiring and plumbing better so you don't need the engine cover.
Imma keep my cover... till I am proficient enough to powder coat my valve cover. Thank you for the information!
Thank you for watching the video 🙂
replacing the spark plugs on the back bank of that Toyota looks like a nightmare.
Ya they were deep, I heard Honda has a better design for access. This is why I prefer inline engines and/ or RWD platforms
They are all bad, this is why they use spark plugs made from exotic metals cuz they know nobody will ever change them out unless they have to..
So with that like Toyota what do you think about the exposed wiring on those plugs on top of the engine. My car has similar plugs with exposed wiring on top. So if I remove the engine cover would it get water damaged or not really. My car's a Pontiac vibe so I don't think it has engine shield on the bottom.
Not really because it's designed to take splashes of water. Also water would come from underneath, not from up top.
Ford stopped putting engine covers on the ecoboost mustang 2021 and up
Interesting, wonder if it's a cost cutting thing or a different issue.
I took it off my 2006 Jeep Liberty CRD. Definitely it was only there for looks and noise control. I mean it probably would be a little quieter with it. I'm sure they wanted to stop some of the sound of the diesel direct injection, valve train and the detonation noise of compression ignition. I don't think it makes a lot of difference.
Just curious, why did you want to remove yours?
@@AnthonyJ350 I was having a fuel issue with air getting in to the fuel lines. The cover covered the fuel rail and lines to the injectors I needed to inspect. Also the oil fill neck went through it. If you didn't pour careful oil would end up under the cover on the valve cover and require removal to wipe up. I should put it back as it does have a lot of insolation in it.
@@MrMikey1273 I see, thanks for sharing.
@@AnthonyJ350 I'm curious why you seem to see a lot of rodent nests in the cars in your video. Is some of it because they aren't driven often? We don't see that here in Pennsylvania unless cars are left not driven regularly. Then we do we problems with mice and even squerells
@@MrMikey1273 I live in an area that has a wet kind of winter so maybe they seek shelter more often from heat sources?
I took my 2011 Avalon engine cover and threw it in the trash! Making the Landfill filled with Plastic Engine Covers!😂
You're suppose to recycle it! Go get it!
Hey Anthony l have 2018 Acura 2.4 . Would you take the cover off if this was your car. Thanks Neil . Nice video
Yes
@@AnthonyJ350 thanks
Haha do not take that cover off. I have a pretty new car, two years old I was hoping to let it run cooler by taking it off. So I removed it and about a week of driving it that the catalytic converter inefficiency light came on, the car is almost brand new and I changed the oil regularly. And the light would only come on after I go high speed on the freeway. I researched it and I have a GDI engine and also the cat is very close to the engine. So the engine must function at very high temps. So the cover was there to insulate and block direct air flow so the cat would work correctly haha
Hate to see if that catalytic converter degrades and shoots material right into the cylinder head being so close mounted to the engine.
@@AnthonyJ350 yeah its a small car and it depends on the city and state regulations some areas consider the manifold part of the cat. And are you familiar with Mazdas and their GDI engines in order to prevent carbon build up from lack of gas being sprayed onto their valves the engineers designed the engine to run at very high temperatures. The high temps helps prevent carbon build up. So yeah gotta keep the engine super toasty.
@@joesmith201212 The engineering reasoning makes sense. But it's counterintuitive to getting long life out of an engine. I guess time will tell. It seems that V8 pickups are the ones that reach the 300,000 plus mark on the regular.
WOW! This is so interesting! I've never heard this before. I have an 07 Nissan Sentra and I recently replaced my cat and both o2 sensors. I left off the engine cover and I got the P0420 catalyst inefficiency bank below threshold code. So I'm wondering if it's because I left that off? I'll put it back on.
@@verinb9 that is the exact same thing that happened to me I thought leaving the cover would help if run cooler and about after a couple weeks of doing so I got the Cat Code I was so puzzled I was buying and pouring that cats clean stuff to hope it clean out and reset the code but it didn't. And my car wasn't that old still under warranty. I think these modern engines must run super hot to help burn off the hydro carbons. My cover has a thick foam layer of insulation under the cover Im unsure if it's for sound proofing or to keep the engine hot. either way I'm telling everyone please leave the covers on the engineers with expensive degrees designed the engine with it on so leave it be
Hello Anthony, thanks for nice illustration. Just curious to know - is there any reason why PU foams are underneath in some of the engine covers?
To reduce the noise of loud injectors and valve train. Customers perceive the noise as "something is wrong".
@@AnthonyJ350 I have the same Sienna and the valve train noise is there even with the cover on..
I have Hood covers on 2011 lexus. I would like to remove them but will it affect the quietness of this vehicle?
Yes it will
a thought I have is that having a cover may help the engine cool down more uniformly as to minimize metal distortion bud to coolingv
On a composit intake manifold? It doesn't cover the cylinder heads
I don’t know if my is200 looks better with or without the cover. What do you think 🤔
Not sure, I'd have to see it.
hood liner plus cover no good retains slot of heat on 90 degree days
Yup, they can have a negative effect on plastic parts and electronics.
ya you dont need engine covers like GM recalled many of there cars to take them off for to much heat trapped that damaged gaskets ect n cold weather it helps the engine heat up faster. in the summer it holds to much heat
Thanks for the comment!
Hmm....my 05 3.0L accord has a cover that goes over the fuel rail but no cover over the intake manifold. THe 04 acura TL(similar motor with many interchangable parts) has a cover that goes over the intake manifold and covers a portion of the rail, but leaves the lower area slightly exposed.
my 2012 honda cr-v has a small lower engine cover, while the 2013 acura ILX(again similar motor with interchangeable parts) has a larger lower engine cover that is more sleek and looks nicer. Also the ILX plug coil cover is slightly larger and "prettier" as well. They sell after market coil covers that are vented for the civic si and acura ilx, that fit the cr-v. My cr-v coil cover is warped and this is common. Vents reduce heat.
THese covers are for looks only and are more fancy on the acuras(more money) than the hondas.
The only thing you want to wrap or cover is your exhaust headers as hot air excavates the exhaust system more rapidly.
A cooler engine is a happier engine. Plastic and rubber decays in heat, not dust and moisture. These covers are not sealed so they do not keep out dirt and any moisture in the air anyway.
Thanks for sharing your insight!
It would help if you were telling what model years these cars were
Thanks for the feedback
Has anyone drilled a few holes in their engine cover(venting it) so you can keep the benefits(mainly noise suppression) while relieving some of the heat and gasses?
I have not.
I took off my engine cover of my acura rdx 2018- and then it back on probably not as good as it was on before, now the engine is making noise and of course i think i just fd up my car. Pushing on the cover loosening up a hose or something.
Beginner mechanic here 🙋🏻♀️😔
Did you pull off a hose?
@@AnthonyJ350 I checked it out and everything seems to be on, nothing loose. I did go on an Acura blog and people have been commenting that this is common with Acuras-a ticking noise..! The car is running good just the noise. Ill probably end up checking it out w a mechanic.
@@sethmanilla1166 Try a good quality oil. Noise is common in a lot of modern engines.
Can you cover the 2006 300c 5.7 liter?? You got the most info I can find on this topic. I wanted to take the cover the first time I saw it cause I want to see the engine
Can you just lift the cover off?
@@AnthonyJ350 I have no idea I was hoping you could tell me, last thing I want to do it rip it off or break something then have to buy another one
@@cliftonsargent1572 You'd have to check a service manual or use a little mirror. Or look for pictures of the cover for sale online and see how it's secured to the engine.
19 buick encore not a big fan of push button start and low eng sound the bottom eng cover is useless if you have to change out stater its more bs to remove
All to make the vehicle more quiet
Hail, the Forester! My 2020 looks just like it. Covers are useless.
Yup
Anthony: *Sees word Lithuania*
Anthony: Anyway, it's not North America
Thanks for watching!
Lmaaaoooo
When it gets -30 celcius in the winter you really want that engine cover.
Why? Work vehicles and emergency vehicles don't come equipped with them.
@@AnthonyJ350 They do here (in Estonia), including all work vehicles and at least the ambulance and police cars.
I live qhere it snows bad should I keep my engine cover on I have a 2018 camry
Try it with it off and see if the car drives any different
Sounds good
I took mine off and now I hear more noise from supercharged jaguar xf
Nice!
they dampen sound especially the padded ones, as for heat an engine loses so little heat through radiation it's not worth mentioning, 99% of the heat is dissipated through the radiator, you could wrap an engine up in a blanket (and Russians do) and run with no problems,
You think wrapping an engine in 40 degree Celsius ambient temperature won't cause an issue on a long trip with a loaded vehicle?
Russian Winter is one thing, but what about hot climate areas?
Took it out because weight saving
Awesome
Got all my hood covers
Nice
I'll save you 20 minutes... The answer is: depends on the car.
SPOILER ALERT! ⚠️
Heat, Moisture & Dust/Dirt kill electronics. You see that engine cover? It's dusty. Let your sensors, wiring, etc., get covered in dust, etc., and ya may gots problems.
How do you explain how service trucks operate on dusty service roads without factory equipped engine covers. Dust doesn't hurt a sealed connector, heat does.
@@AnthonyJ350 true, but heat destroy the wires and the plugs. The cover increase that heat. In a 95 degree country is worst.
@@joseluiscolon4640 I agree
Sales gimmick for women or people who do not know anything about mechanics and it makes them feel comfortable. without the cover the engine looks complicated and scary.
Yup
God, how many rats are out there?
Apparently a lot, I was surprised too with every hood I was inspecting. A lot of people park their cars outside and it's starting to get cold in my area
@@AnthonyJ350 It's mostly spiders for me, great little artists they are.....(until the engine starts)
If that's what you call clean, I'd hate to see it dirty.
An engine covered in spray from driving through large puddles or going offroad. You don't see too many vehicles used in harsh environments, do you?
@@AnthonyJ350 i live in a rural area in Queensland, Australia. What do you think? 🤣
@@aidenater You guys just have dirt and dust. It doesn't snow so you never have to rust proof. Dirt and dust stick to rust proofing. Plus it never snows there so you don't have to deal with roads being salted or the tons of rain we deal with on the West coast of Canada.
@@AnthonyJ350 oh, is that so? Ah... that must be why I've received 3 severe weather/storm warnings in the past 24 hours. xD you might want to do your research first mate.
@@aidenater You guys salt your roads and have slush on the roads in Winter?
07 Mazda CX7 engine cover has to stay on
Part of the intake track?
@@AnthonyJ350 no it's a cooler on top of motor and engine cover traps and sends cool air to it
@@derrelldraper996 Ahhhh ok. I would just take it off every oil change to do an inspection then put it back when you're done.
