Plow truck overheating at high speeds - advice needed

    Okay, so here is the deal, I have a 2003 chev 2500HD that is overheating on the highway when running the plow. I have tried lowering, lowering at an angle and everything with no luck in getting air in the grill. I have been doing research and I have seen plenty of people saying well don't drive over 45mph, but sometimes the highway is the best option so I am looking to resolve the problem in other ways than just slowing down and not taking the highway.

    I am planning on beefing up the suspension with add-a-leaf/roadmaster in the back, and torsion and possibly timbrens up front after the season so I am looking to possibly be sitting up 2" higher but I do not know if that will even address the problem, let alone solve it. That being said, I am running a western straight blade, and there is no rubber strip along the top so my idea/plan was to buy the rubber strip kit and mount an electric fan in front of the radiator and when I get on the highway, turn the fan on. That would help draw some of the air in I would imagine. The last thing I was thinking was to make an "air tunnel box" of some sort to mount of the plow to try and pull a draft.

    I know I can also get the fan clutch kit which is not out of the question at this point in time.

    Any good suggestions on products/vendors for the rubber flap or even an air deflector tunnel thing, or just find the best price and go with it?

    If someone has a problem with over heating seems like its always on a Chevy

    I say a Fan cultch kit should fix it or a radiator with bigger cores

    Like on my truck I block half of the radiator with cardboard so my truck will heat up

    even when I hit the highway 9 times out of 10 the fastest I will go is 45mph b/c of the road conditions.

    Drop the plow a little while driving to get air into it.

    If you are dropping your plow sufficiently and still having a problem, you need a new fan clutch. Also make sure you have enough coolant.

    Tried that... I had the bad boy bouncing off the ground a little. Darn truck just sits too low I think. :confused:

    I got a hell of a deal on the whole setup, and most definitely worth the headache of fixing the minor problems.


    Think the severe duty fan clutch at local autozone would do the trick?

    Bump.... hoping to get something ordered or picked up sooner than later. Will one at a local parts store work or do I need to order a special one?

    Thanks.

    Best one you can get at Napa should work fine. Napa parts tend to be better than the other box stores in my experience.

    We had this problem on our 2004. Upgraded fan clutch solved the problem

    My dodge is having a similar issue, although not actually overheating, it's just running warmer than normal because the plow blade is blocking the airflow.

    If I drop the blade low, it runs almost normal temp, but I decided to change out my fan clutch anyway. Ordered one from Slammazon, as the one that I have in there now is one of these chinese knockoffs from Autozone I bought about a year ago.

    More importantly, I'm going to change the Rad Cap again, and see if that makes any difference as well. Seems as though there are those who think that poor radiator cap design attributes to head gasket failure,so..... who am I to argue.

    I'm curious how many of you guys use the defrost setting on the truck to help keep the engine cool? I use this and it never gets past the half way mark on the temp gauge. I run it full blast as much as I can. when I get to hot I either open a window for a bit or turn down the fan until I cool off.

    You are correct.
