    Have not tried it with plow off, but going down a road no matter with the plow way up or way down. Angled or not, heater on or off. Old 98 never did anything like that. Climbs right up to 260 and all the bells and whistles go off. Two dealers say Chevy knows about the problem and does nothing about it. I can not belive I can buy a new truck (with plow prep package) put 8000 miles on it and they will do nothing?!?!?!?! Changed the thermostat as it seems to climb up there once and then drops back down before the whistles go off or after you are on the side of the road for a while it drops back down and never goes back up. Does not do it idling or plowing.
    Any thoughts would be appreciated. P.S. Western straight plow if that makes a difference.

    Was the grille pasked with ice and snow? Just a stab in the dark, but I noticed my temp creaping up on my '03 2500hd and when I got out is was packed with ice. Good luck.

    There is a revised clutch fan for that truck which will solve the problem.

    Not necessarily the grille but is the A/C condenser plugged with fine snow? Try putting the heater selector in the bilevel or A/c position in order to have the fan(s) come on to draw cooler air thru the condenser and rad core. Also, put on a higher rated pressure cap like 22 lbs.

    NOTE: In order for max air to move through the core, air must be able to move out of the engine compartment. Make sure your not plugged up under the oil pan and transmission, or frame cross members. Try knocking off some of the undercarriage ice and snow pack. As a last resort, try cracking the hood open to the first notch and see if that helps.

    Do a search for "overheating" or look in the chevy section - it is talked about quite often.

    I know what proplem is your plow is blocking the airflow to your raditor.THERE is a product called the coooler you mount on plow it redirects the air to your raditor and works great.SPREAD THE NEWS.TO get one Email shannapavey@yahoo.com. RTP

    there is a t.s.b.

    go to any reputable dealer and explain the problem and tell them there is a technical service bulletin addressing the issue.another reason i beleive they(all manufacturers)dont care about what there putting out anymore.quality is out the window.i have an 01 2500 hd and had to have the clutch fan replaced for the same problem.you would think by now they would have corrected this.no more new trucks for me.ill buy old and restore.i beleive 87 was the last good year for a real truck from gm

    Just a guess. Western plows sit a long way off the front of the truck. They really change the airflow. If you don't have a snow deflector on the front I would put one on. This makes the air curl more and will allow more air to go over the plow and through the grill.
