2015 silverado overheating with plow

[jpcons]

Well I know its not the time of year but it is coming. I bought a brand new 2015 silverado work truck with the plow prep package on it. I traded in my 2013(biggest mistake) and had the plows swapped from the 13 to the 15. When drivng over 40 mph (in the winter) the temp starts to climb to dangerous numbers. I had the GM engineer involved in this problem and they are aware of it but have no cure. There answere was not to drive over 40MPH. Speed limits on the way to work ar 55 MPH. The engineer said that at 40 MPH the plow creates a vacuum and pulls heat from the engine through the radiator. The difference I have noticed was the 2013 had holes in the bumper and the 2015 does not. This only happens on the 1/2 tons due to the 25-35 has holes in the bumper for the cooler. Any one else have this problem or a fix?

Is it a 1500? What cab?

I wonder if it has anything to do with the new di engines as many vette owners are having over heat problems when using their vettes as intended on a track. Like much of everything else while quality is up in some areas that are more visible it seems to have declined in others that are not areas that one can easily spot. The cooling systems might of gotten the short straw on things gm went cheap on imo.

My 2014 1/2 ton dc 5300 does the same thing, I reinstalled the air dam for a slight improvement but by no means a fix. These trucks seem to have an enormous amount of under hood temp created as well. Watch the trans temp anything over 225 is in danger(according to my tranny guy)

Drill some holes in the bumper?

All you need is a tune that will crank your fans on aggressively. With the stock tuning the fans aren't really crankin' until it looks like you're "overheating" on the guage.

it is a 1500 standard cab

Drill some holes in the bumper?

really don't want to drill a bumper on a brand new $35,000 truck

I know were a little late to the party here, but we may have a solution. If you have a snowplow package with your truck we can help. Our accessory universally installs on any snowplow and will absolutely solve your overheating issue. Check it out at:

That happens to me as well, all I do is lower the blade to a few inches off the ground and tilt it all the way to one side or the other and there is no longer a problem.

 

I'm pretty sure that's all you have to do as well.

Plowing with half tons is just loooking for trouble to begin with. Just not enough cooling or suspension.

That said, there isn't much you can do, other than removing the plow when you need to go somewhere other than local driving.

Also, winging the plow full left or full right will disrupt the vacuum effect somewhat.
