    i have a 05 dodge with a cummins diesel.i just installed a meyers st 7.5 poly plow.its running hot.with temps between 203 and 212 common will the truck is lugging.i've hit 219-221 before.i've tried running in tow mode,running with the plow in every postion.low/high/side to side and straight.i've even tried adding a piece of plexiglass to the pump unit to try and deflect some air into the radiator.any advise.i'm thin g of changing the clutch fan but how much help is that and will that make the truck run too cool without the plow on.thanks everyone

    Doesn't sound normal to me....My truck doesn't heat up at all when running (and I have a chevy-so you know it sits real high!)-I have a friend with a 94 cummins and his doesn't either. Sure you don't have air in the system or anything basic like that? I had a bad fan clutch once and it caused it to heat up significantly because it couldn't pull air-but it was bad enough that it would spin with barely any resistance.

    Is it an electric fan on that truck? I guess I assumed because he said he was looking into a new clutch fan that it was directly coupled to the engine. If it's electric that's a whole different story.

    the fan is coming on but its a tall plow and it seems to be blocking all the air to the radiator.its not an electric fan.thanks for the replies

    i think you need a new fan clutch or a heavy duty one. mine stays around 190-200 with the plow at any position.

    Do run live in a area of dirt roads or heavy dust??? It is rare for a Cummins to run hot on a 3rd gen 5.9 truck 2500/3500 !!! Swap out the clutch fan and give the cluster of radiators/condensors and coolers a good wash from the front with the hood up. Watch for brown water or muddy runoff.

    On mine I can run down the Hwy doing 65 blade all the way up, towing a loaded trailer and still runs in the normal range WRT temp.

    Make sure it is only doing it when you have the plow on. If it is then it is normal. mine will do it once in a while. I have had mine spike pretty good going up a steep hill or if I am on the pedal good, but comes right back down. Just have to travel with the plow lower to the ground to allow for airflow.

    I have had this discussion a few times on other forums. All say it is OK.

    Mine gets a lil over 200 maybe 205 sometimes with the plow on a warmer day never overheats I'd say if its not overheating dont worry unless its getting real hot

    Try snapping a pic of the truck with the blade on and all the way up. Side profile would be the best!!!
