Plastic Engine Cover

linewarbr · **Posted:** Thu Jun 18, 2009 10:22 am

It has been 95+ degrees here in South Louisiana for about the last 2 weeks. I am wondering how many of you out there have ditched the plastic engine cover. I've noticed a decrease in my mpg and engine performance with the increase in heat.

What is the good, the bad, and the ugly of putting the cover in the recycle bin?

on my 300sd i removed the liner on the hood (was falling apart) about 2 years later the clear coat started to peel on the hood directly over the engine. Its there as a heat / noise shield. The paint on the jeep might be better... not sure. I have mine off right now because i was working on it (just didn't put it back on yet) but will put it back on soon

Cover on and it stays on -I see it as better protection to keep heat away from sensitive areas--

But check this:

My jeep is at an ASE Certified shop right now for work on the ABS system- certified tech opens the hood and says "What does CRD stand for?" and "this Liberty really has a diesel?"

So go figgure--

i would take it somewhere else then. when i was looking for a shop i always asked them if they knew how to start a diesel. all of them would say "YES". Then i would ask (how then?). 60% would say you just crank it.

Maybe this was a certified ABS only tech-
Since problem is not engine/545rfe related I am going to try to work with these guys--

Umm start a diesel- turn key, mash go pedal,look to see who you just smoked out! -- JK!!--

that's true. although I'm even worried about the trip from the parking spot to the bay! I may be paranoid but even when getting new tires i just bring the wheels. I load them up in the back of the truck and drive over with them. Cant mess up something thats not there!

You should have a significant decrease in your fuel consumption right now because it can't leave the driveway without your ECM :-)r

Lettuce know when you get it back with the Green touch.
BTW, my cover stays on unless performing maint.

In the case of our CRD and probably 50% of the USA, those guys weren't that wrong. The need for the glow plugs isn't that significant during much of the year for the lower 48. Personally, I don't even SEE the glow plug light most of the year, because Florida has only 2 seasons: summer and Canadians. Winter? Thats for other states.

As far as the engine covers... I DO suggest the under-hood cover, the paint on any vehicle isn't strong enough to put up with that baking heat from underneath. The top cover of the engine however... It's somewhere in my garage. Pulled it shortly after buying the CRD. I want to SEE my beautiful engine when I open the lid, not another lid!

agreed. although i HAVE had a DEALER blow out my starter because he didn't know how to start it. Fun times getting them replace it for free. I miss that car

I don't know if I can answer the poll if it ask if I did both.

If I removed it's off
If I kept it's on

Well mine is on anyway. I don't know what harm it's doing, mine never run hot even pulling a steep grade while towing.

I did not vote due to the ambiguity of the phrasing, but my engine cover is on the rafters of my shed.

I voted, yes, but could have easily voted no. :shock:

I removed the engine cover 3 years ago. Its hanging on the wall in my garage. I believe its only purpose was sound reduction, and I wan't my tractor to sound like a tractor.

I don't even remember where my cover is at this moment. I took it off 2 years ago, mainly because the grit and grime collected at the oil filler and I was afraid it would sprinkle in when changing the oil.

No paint damage.

I removed that vanity-shield sop for soccer moms'n'dads - Diesels (and wimmin) are for manly men......................

Winter on, summer off.

Hehhhhh. Hilarious. Why didn't you and honey_don't just pick the 600 thread count?

*Note to self, check grammar to avoid flaming, or wear Nomex. . . * :shock:

Thank you for the input. I tried to edit, but I can't seem to edit the poll itself. Oh well. I believe that mine will be coming off then.

But would I still then be keeping it. . . ?

I ended up going with th 600,just cause I got a lil confused.

Thanks for asking,I was wondering myself.
Would the engine bay have somewhat cooler temps due to better air circulation?
Also wondered about the paint.
Seem's paint is good,What about bay temp?

Mine is off for several reasons. #1: A diesel engine should be heard and appreaciated. #2: I like to see my engine. #3: It collects a lot of crud underneath it, as well as having oil seep out from the oil filler and look like crap. I can't see how it could possibly help with engine cooling with all that fiber insulation and virtually no space for airflow underneath it.
