    hey guys, i just picked my plow up from the service shop and have a problem with the engine getting hot, real hot. if i drive at 60mph it gets hot and the light comes on, if i slow down to 50mph or so it cools down a bit but not much, i have had the plow in all 3 directions and still does not make a diffrence. if i stop and park it cools itself down in a minute or two....what gives. also the plow seems to be tilted on the drivers side a bit is that normal for a western uni-mount plow...need help

    The plow is blocking the air flow to the engine, what type truck? Also the plow companys don't want you driving over 45 mph I think with the plow on. Look on the web site for your type plow.

    I am guessing this is a Chevy or GMC as this problem is common in these for some reason more than others.

    What I have seen from others on the board here is getting a new fan clutch. They do sell a after market air deflector but I am not sure it would mount to your plow frame or not. I use to use one on a older(89) GMC I had with a western plow on it. But that was when the pump and lights stayed on the truck and you mounted it to the bracket for the ram arm.

    Otherwise i would say just drive under 45 MPH like I do with my GMC if I have to use it because I have the same problem with that truck. If I ever have the plow on it now though it is because of a emergency and snow is on the ground already so i wouldn't drive it that fast anyway.

    I have drove to Michigan and back with my blade on my Ram but i would never do it in the GMC and when I did have that truck as my primary truck and made the trip the plow was in the bed because it would never make the trip otherwise. On my Ram there is no difference at all in temps running 65 MPH

    I've seen more people putting wind scoops on the plows to direct some air flow to the rad. it's and idea. or try traveling with the plow down a little enough to clear the ground, but low enough it's not blocking all the rad. I know mine gets a little hot, I normally drop the plow a little, and it cools right down.

    There is a SB out on alot of the HD trucks. Do a serch here for chevy's overheating. They need to replace the fan clutch if I remember right.

    I have a Western Unimount on a Gmc. The plow sits level, if your frame is ok and the adjustments are proper. As far as the overheating, Definately change the fan clutch. I have no problems with mine, but I also have a 4 core radiator. What type of rad fluid you got in it? I replaced my 3 core, with a 4 core, and run the newer Dexcool in it. I can drive down the road 70mph with the plow on. No problems. Just some advice, to check. Might help you. Good luck

    over temp and plow

    its not bent i dont think, if i raise it about 4 inches of the ground and rotate it left to right the left side corner will touch, but the right side corner doesnt. it has a piviot pin in the center im thinking it could be worn a bit on one side, plow does have alot of play, but im thinking it should? i cheked around for the over temp problem, im taking it in on monday to get the fan clutch checked. i did a serch on line, but found no results for similiar issues with the 3500 4x4, it has dual batterys witch means it has a plow package, so why wouldnt it have a heavy duty fan??? was that an option or something...thanks to all for your help...

    Even if it had plow prep there is a problem with the fan clutch, make sure you give your dealer that TSB number and ask him to look it up. A guy that subs for me has a 04 that had the same problem, brand new truck 2 years ago and would over heat. Dealer put new and better fan clutch in and his problem went away. ITS THE FAN CLUTCH AMD DON'T LET THE DEALER TELL YOU ITS NOT. There have been many threads on plowsitre about this and each and evryone was a bad fan clutch.

    Good Luck Mike
