Are there any problems that can be caused by not using a winter cover???

It is optional ....For quicker warm-ups and more heat in extreme cold temps it is recomended but not a must and A diesel will run more efficent at normal operating temps ...

I don't think it will damage anything but your truck would warm up alot faster.You would also get better fuel economy. The faster you get up to full operating temperature the better.

In my opinion the main grill cover need a velcro flap that you can open. That way you could regulate the cold air to the radiator.

I would, but it's too cold up there!!!!

I am not using the cover in Vermont. In sub-zero weather, this means that the engine operates at around 180F in light throttle driving, but when I have a sustained load (such as climbing my 6% hill for the last 1.5 miles home) it gets back up near 200F


Remember that the lowest marking on the temperature gauge is 160F, not 100F like most vehicles.

Had my Check Engine light come on and stay on. Took truck in and dealer said fuel sensor temp gauge was the problem. Fixed it and I got truck back. A week later the light came on again, called dealer and they said it was the winter front being on when the temp outside was above 0. The fuel sensor was getting a false reading. Therefore no big problem. The book does say to only use front cover during -0 Temps. This is just for eveyone elses info. Hope it helps some of you guys living in the North. Let me know if anyone else has had this happen??. Thanks in advance.

If you dont use it, the ice and snow from the road could get into the fins of the coolers, the salt can get in there also and corrode all those vital components. This damage is not covered under warranty and is considered neglect. I personally use mine year round to gaurd against bugs in the summer. The cooling fan will keep the engine temp at bay.http://www.dieselplace.com/forum/smileys/Confused.gif

A diesel runs better and more efficient when it is warm. I drive 25 miles to work, and on cold nights, 0-15F it just about gets to 190 by the time I get home. That is only using the engine grill cover and not the trans cover. You will not do any damage, but will get better fuel mileage with the cover on.

I just decided to run with the upper cover on and leave to lower cover in the garage. Partly because it was easier and also the temps around here are slightly above zero. Does anybody see a problem with this?

I also run just the upper cover on to block the radiator. I have heard people having problems with rust or corrosion when running the bumper cover cause it holds salt and pebbles and rubs into the bumper. I also relocated my temp sensor so it would still read accurate when the upper cover was on.

What Is Normal Operating Temp 170-200? Mine Does Not Over 170 It Was About 13 Today And No Cold Fronts

Also I Guess It's Better To Be Ignored Than Not Ignored At All Or Something Like That. Are You Looking For Mirrors For Your Truck?

Is the truck supposed to come with the cover? Or is it an aftermarket thing? I did not get one with mine. ANY HELP???

It Is An Option For The North East, Were Not Cold Enough

When I took delivery of mine in northern NJ in Jan 2003 it came with it, under the rear seat of the CC

I didn't use mine at first. But finally did break down and put the grill cover on. It does seem to warm up faster. Also I see the transmission actually warms up on the drive to work now with it on. I am still not using the bumper cover. I just can't see where covering up the two small holes would make any big difference. Also the grill cover is easy to put on in comparision to what it looks like the bumper cover would be.

I've used the grill cover only for now my third winter season with the truck. Never have used the bumper cover and I agree with Larsonem that it looks to be much more trouble than it's worth. It really seems to make the engine happier in very cold temps and the transmission will stay pegged cold if you don't cover that pretty efficient cooler up in front of the radiator.

It's so easy to put the radiator cover on you might as well do it. Before I put it on the heat would only get hot while pulling long inclines. The engine temp would actually move up while climbing the grades. Driving two hours to PA the trans temp wouldn't even move off 100F. Now I have heat all the time and the trans temp sits at about 140F. Should have done this a month earlier. These are for temps between 10 - 20F and sometimes single digits in PA.

I've used the upper portion but not the bumper cover and noticed it really does help with warm ups. I also notice that it greatly affects the transmission temperature. Saturday, when it was 66 (!) degrees here, with local driving the transmission was almost 200 degrees and the engine was running about 190. Without that cover, the transmission stays cold, maybe 150 around town in the hot summer. So it seems to have a great effect on the transmission, which is probably why the manual says not to use it when towing, regardless of the outside temperature.

Any advice on where the temp sensor is and how/where to relocate it? I've noticed since running mine that when it's +5 outside my temp reading shows it to be about +35.

Thanks much....

Only problem I have with the cover is that once I put it on, it seems to guarantee 2 months of bitter cold weather.

I also have only used the grill cover. The bumper cover is huge, cumbersome, poorly designed and seemed to be a pain to install.Especially when you consider it will cover only two small holes. I solved this problem by putting some closed cell foam that I form fit to the holes and painted black. They work great and go in and come out in seconds.If I knew what I was doing I would post a picture. With the temperatures we have had the past two weeks(below -0 every morning and -20+ a half dozen days)the cover sure helps.

That's what is causing this nasty weather. http://www.dieselplace.com/forum/smileys/Big Smile.gif


It's a Groundhog thing...


Seriously, I had the dealer put both on because of new fit issues, then I took off the bumper cover and put it in the garage. It collects road dirt like crazy.


I think normal temp for the duramax is about 203 deg F. At least that's where mine runs when it's warmed up and under load.
