Winter front on 6.7?
 

Why doesn't Ford want us northern drivers to use winter fronts on our diesel pickups? Thanks.

Where does it say to not use a winter front on your truck?

Last winter, we traveled to Kansas City from Central Texas. The Truck had a really hard time warming on the hiway, up so I went back to my ole Farming days and put a piece of cardboard in front of the Radiator. Not a big piece, but big enough to slightly reduce air. Wow what a difference. I monitored temps with my Scangauge and it never heated anymore than normal summer driving. Once headed back and got back to near Ft. Worth, it started warming more and more, so I pulled the cardboard and back to normal we went. So in answer to your query, I do not see any why you cannot put a winter front on your truck. I would think it would help in snow issues also.

If you reduce the airflow too much, you could cause the fan blades to suck themselves forward into the radiator. Instead of blocking the front of the radiator using a piece of cardboard, block the front grill with some vinyl. This will help prevent air being forced through the radiator by driving down the road but it can still suck air from the bumper area. Making a couple vent holes or flaps in the vinyl would be good too.
Here's a video of the vinyl installation:

I have the Fia WF922-18. It comes with winter cover with two openings you can velcro open or closed. It also has a bug screen for summer

you can get it off eBay for less than $75 with free shipping. Not sure what the price is on Amazon.

My Ford dealer said not to use a winter front. I had a Chevy and Dodge diesel and they both came with nice snap on winter fronts. I like the idea of a nice fitted grill cover. Thanks.
