Instead of starting a new thread I figured I would try here...... I picked up a snow plow for a friend the other night. It was about a 20 minute ride and the temp got a little over 190* possibly right around 210*-220* , and the outside temp around 45-55*. I've already relocated the puke bottle and cleaned the radiator. Just wondering if anybody has run into this ,although when it is cold enough to snow I have a feeling this may not happen.

Thermostat time and maybe a fan clutch.

 

Right now it starting morning temps is about 35-40*F and afternoon highs are in the 50's... I'm running my winter front the grill is completely covered. I never get above 195*F. If you radiator is truly clean where you removed it and power washed it till your can see through it. It shouldn't have any issues at all. Even my radiator still has to be remove from time to time to be cleaned.

Moved...

Snow plow mounted in the front or in the bed? When we used to plow in my boss' duramax the temps would get toasty because the plow was blocking the air coming in the front grille going down the highway.

Stupid  question, but have you checked how full the radiator is? If it is full, then the picture that Mike posted is probably your problem.

Shouldn't be any different than what I get for coolant temps. 193-195*F... I'm completely blocked off on the grill.

Yeah i'll be removing my radiator and giving it a better cleaning. Any suggestions on cleaners?

I used simple green and let it soak for an hour or two. Then ran up to the local gas station and used the pressure washer

when i rebuilt brutus, it took an hour to clean the radiator. i soaked with simple green and used a hose sprayer to force through the fins (without bending them) gotta go straight at the fins and push all the oil and crap out. holy cow there was a bunch of junk in mine...   runs great now.  also you can use brake cleaner if it hard to get out packed in oil/dirt then hose out. you wanna be able to see through the radiator.

be careful using a pressure washer, the force will flatten out the thin fins and block the rad totally.  i use a garden hose with a spray attachment held very close so there is no deflection to bend anything.

Down at the shop we use Super Clean...

Spray it on let it soak on warm surface like 100-140*F engine is excellent. Next fire up the power washer and blow the crude out of it.

I actually found a tub (not the one in my bathroom)"This time".. that would hold the radiator (flatwise) and hose fittings pointed up.. and let her soak overnight. simple green, I believe. filled the tub with just enough so the soap wouldn't run down the hose fittings.

Just hold the pressure washer at a 90 degree angle and there shouldn't be any problems! Have done this with all of my vehicles and farm equipment 

yup perpendicular is good ^^^^^^^ this

With my 3000 PSI washer I tend to keep at least 1 foot from the radiators and coolers. But there is nothing better than removing them and getting the job done correctly.
