i have a truck that i use for plowing and was wondering
if any of you could recommend any thing to help run cooler. runs
about 210 or so running down the road, with it in fourwheel drive
and run about the same in two wheel drive. i have changes the
thermostat to 160. so any help would be great. thank you in advance.
what is the outside temp, and is the 210 with the plow on, or off?? if it is with the plow on, try running with the plow down about 2 inches off the road. i have seen dozens of trucks overheat because the drivers had the plow up blocking the wind flow to the radiator

The real fix here is a properly calibrated clutch fan or even a manual flex fan while plowing because of extra drag and flow restriction. I have been plowing for over 20 years now and I fix my trucks so they do not overheat of have to run with plow dragging the ground to keep from overheating.
what do you mean by a properly calibrated clutch fan? yes i do run with the
plow about two inches off the ground some much need help would be greatly
appreciated so i dont have to do this. the truck only has a three blade fan on
it i was thinking of using a 5 or 7 blade fan. how many row radiator do you run in yours. i do beleave this one is a three row. thaknyou in advance for any advice.

Clutch fans have a bi metal sensor on the front of them that controls the operation of the clutch based on the tempature of the air passing over it after going thru the core of radiator. In cold weather it is possible to over heat engine sometimes with a clutch fan because the air is so cold going into radiator that it may not be heated up enough to operate clutch fan. Adding more blades will not help by itself if the clutch in the fan is not operating correctly in cold weather. In you case you might do well to purchase a aftermarket flex fan and adaptor and replace your stock cooling fan in winter (because you only have 3 blades and a calibration problem) and this would keep engine and tranny cooling plowing. If you want to try to recalibrate you clutch fan you will find instructions on how to do so in link below.
there are a few things missing before anyone can realy help. what truck? what motor? what condition is the radiator in?? have you done a flow test?? is there a temp difference with the plow on verses plow off? are you going by the gauge in the dash, or do you run an aftermarket gauge? i have never had to do any modifications to my trucks after adding the plows and can run all day in 90º temps in the summer with the plow in full up position, because they were ordered with larger radiators and plow packages.

Your are lucky because more often than not some trucks have issues with a plow present and 99% or the time it is from disrupted or not enough air flow through core.
I have found when plowing to have the plow up and angled all the way left is the way to go. Never had a truck overheat or even begin to for that matter.

I rarely angle in transport. Many years ago I had one old truck start over heating on me. I replaced the clutch fans clutch hub and never had anymore problem wiith it. Generally 1/2 ton truck are more sensitive to the problem than heavier duty models because they tend to have the least aggressive fan cooling to maximize EPA rating for MPG. .
