Diesel weather front

I finally got a weather front on my truck after the 3rd winter. Ford quit supplying them on the new trucks and the aftermarket ones had snaps to install on the grille. The good folks at Alaska tarp and tents put straps on one for me so that I could but the snaps out of sight under the hood.
 
I pull the engine fan off in the winter and then use cardboard to cover the radiator I use to have a cold front but it went with the old truck I had .
 
My dad did that, had to leave heater fan running, but he forgot one time and it boiled over.
 
Only time I've boiled over is when pulling long hills and I forget to slide the cardboard over I use to pieces of cardboard that way I can slide it like a sliding window to regulate air flow .
 
Be careful with the cardboard in front of radiator. I put it in my truck , got about 6 miles down the road and over heated and blew the bottom hose. It split about 6 inches lengthwise. Of course it was original on a 94 F-150.
 
Only use cardboard directly against the radiator if you want to over heat your engine and blow it up sky high!

I've used winter fronts on all my pickups since 1981, a 300-6 F150. With the winter front away from the radiator air can still flow thru the core and cool the engine. With cardboard against the radiator you completely take that part of the radiator out of the heat transfer business. An engine sitting idling with cardboard covering 90% of the radiator will overheat sitting still in less than five minutes.

Son's brand new '14 Ram 2500 came with a winter front as part of the cold weather pkg.
 
I've used cardboard off and on all my life. Course, mornings like this one (+20F) is about as cold as it gets. The temp gauge on the dash tells you how hot the system is and once you open the stat the whole shebang is about the same temp. Course I didn't get on the interstate and do 70 either. So I never had an issue and I can recall years ago that I too took the fan off. However that was more of a nuisance and only did it a couple of years.

I don't know why you would. With the T'stat closed the cold coolant stays in the radiator and with the fan not turning it slows how fast it cools off any way. I thought that seventies technology had it covered.
 
One slight correction here....
A GASOLINE engine will overheat at idle. Most diesels will idle all day without even reaching operating temperature. I once drove a Cummins N-14 over 30 miles with a blown water pump without overheating. Ran it up to speed, kicked it out of gear, idled it down to almost cold, and repeated the procedure. Diesels only get hot when you make them WORK.
