Do Engine Covers do anything? | AnthonyJ350

[@mwanderson667]

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.

[@AnthonyJ350]

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.

[@mwanderson667]

[@RockandrollNegro]

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.

[@AnthonyJ350]

But why don't all cars come with one?

[@centralintelligenceagency9003]

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.

[@iamnikobelic]

That's a myth lol... the only thing that a hood liner for is sound deadening.

I'd just leave it off the whole time

[@cards-vs7hv]

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?

[@001dman]

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 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.

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.

[@WAncouvOR]

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.

[@AnthonyJ350]

Not really because it's designed to take splashes of water. Also water would come from underneath, not from up top.

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.

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

[@AnthonyJ350]

Hate to see if that catalytic converter degrades and shoots material right into the cylinder head being so close mounted to the engine.

[@joesmith201212]

@@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.

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.

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

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.
