Question:
If this is your 1st winter as a driver and you run in the COLD regions of North America chances are you will be using a WINTER FRONT if your truck is so equipped.
Be sure to check in the OWNERS MANUAL for the CORRECT amount of COVERING that your truck requires for certain temperatures.as TOO MUCH will hamper the performance and could cause damage,

Answer:
Good information except for the fact that very few Trucks today come equipped with a Winter Front. "Modern" equipment does not require them and except in extreme conditions Manufacturers frown on their use. A properly operating
cooling system negates their use today. I personally have failed to see their usefullness since the thermostaticly operated shutter system came into
existence.
Answer:
My 2000 has a WINTER FRONT and I have not see too many with thermostatic shutters lately they sort of died away.
Wouldn't extreme be the COLD REGIONS of North America
Maybe these guys do not know what they are selling

Answer:
Shutters are long gone away due to their erratic operation. Seldom worked well after about one to two years.
Most modern trucks do not need weather fronts. However, there are still plenty of trucks (mostly the older Petes, KW's, & Classics) with the big radiators that need the fronts.
Like posted though, if your truck needs a front, make sure you are allowing enough air through so as not to damage the engine.Sometimes you have to dig through a lot horsesh#t to find the pony.

Answer:

Of course they know. They are in business for profit,the value of what's sold is of no consequence. They know that some Drivers are the fools that
purchase valuable products like these...

Answer:
While I've never needed a winter front while rolling down the road, there's been a few times that I've slipped a piece of cardboard between the bug screen and grille at night time.
When your motor won't stay above 150 degrees idling at 900-1100 RPM's because of -20 degree temps and 40 mph winds, ya gotta do something if you can't face the grille OUT of the wind.
Just make sure you remove it before hitting the road the next morning.

Answer:
We had to use cardboard and some bungie straps up in MN last week. The temp on this KW never gets much above 155 and it wasnt even doing that up there. Heat was useless, even idling it up didn't do much.
We knew we had a small water leak so stopped at shop and got waterpump seal fixed. Still maintaining about 155 all the time (Cummins ISX engine). Is this normal? No owners manual in truck so don't know what it calls for.
BTW, the company shop told Hubby it was OK to use the cardboard and see if that helps, so I got the impression they didn't really know or care.
Answer:
For most DIESELS the operating range is 175 - 205'F.
Winter fronts are useful in saving fuel as the efficency improves 1% for every 10'F your engine operates above 165'F. Cardboard will do in a bind just do not cover more than 75% of the grille.
You reduce engine condensation , which stops the formation of sludge , carbon deposits , and acid formed by OVERCOOLING.
Have 6 new T600's in the yard all came with winter fronts, have not put them on yet as we have only had a few cold days up here and they all run into the Southern US .
Other trucks have them on and the drivers know the closeup procedures , even have belly tarps available if needed.
Last truck I had with SHUTTERS was an old FREIGHTLINER COE back in the early 80's

Answer:
155 does seem low to me. Every truck I have ever driven the water temp was alkwats between 180-195.
My guess is that you either have a thermostat stuck partially open or your coolling fan is not shutting off.
Answer:
Shewolf: try delivering that engine to them in a 50 gal barrel and they will start to care a whole lot. Like UT says, there seems to be a problem there. Insist that they check it out.
Take no for an answer if you want, it is your hind end sitting out there on the cold cold road waiting for the tow truck.Sometimes you have to dig through a lot horsesh#t to find the pony.

Answer:
I thought winter fronts went out in the late seventies (except harsh Canadian conditions). As for shutters, FREIGHTLINER wouldn't build my 76 COE with them and it wasn't a BIG CAM CUMMINS.
If for some strange reason, a winter front is desired, make sure you check with the ENGINE MANUFACTURER on needed air flow. With intercoolers and air exchangers, it wouldn't take much to cause some serious damage. Also, how to run the winter front is especially important with today's clutch fans regardless of method of activation. Usully they want the airflow over the fan clutch hub as airflow only on the blades at one position can lead to fan/clutch damage.
I think what most chassis makers are doing is installing aftermarket kits for customers that think the old technology is still needed. I would like to have the fasteners installed for a bug screen but if one feels they need a winter front with today's technology, they are likely to cause more harm than good.
If a tractor has late technology and will not heat at idle (even with idle-up or ECM command) something is wrong.
As for shutters, I remember when they were popular on THERMO-KINGS...
Could you imagine a big truck bearing down on you from behind and as he closes, the shutters close and have those big teeth on them? WE DON'T NEED NO STINKIN' GRINGO FLAG!"


Answer:
Most I have driven and everybody else run 180-195 also. That is ' driven'. I haven't seen one yet that in (-10) -+10 heated (maintained 180-195) like they should while idling without reving up a good bit or using the cardboard(front closed) deal. If it's cold enough even going down the road will compromise the heating system in a truck. 155 (idling) should be enough to keep you warm (if the wind ain't blowing 30 mph ) but with the drafts, glass, low insulation , area to be heated in a truck it gets cool sometime.
155 going down the road - you need to have it checked.Whoa is me. Yup, put the brakes on the trucking crapola and haven't looked back.


Answer:
Using them this morning ambient temperature is -25'F and the windchill is -45'F

Hmmm, seems mine still work perfect after 45 yrs
Every day I fire it up, they close without fail, then open after it hits +160 degrees. Summer or Winter
Darned old trucks.....no plastic to break...
