getting to that time of year again and dont have a leather grill cover like i did with my 08, do they make one for the 6.7 grill? anyone doing somthing like this? thanks, Cory
Always curious how much of a difference these made and if they are totally necessary. I can see running them if you're driving around a lot in the snow/freezing rain, but if you are like many people and home during those times I'm not sure. Now if I were plowing I would put one on for sure. Have you ever looked at your radiator/intercooler after a good plow? Completely covered, especially if you're plowing at any speeds.
I know they greatly help in the winter time with warm up and keeping the engine warm in very cold temps, but that's about all I know about them, I don't seem many diesel running around with them these days.
My ford dealer said with these new truck your not supposed to put a winter front on them or they won't get enough air flow. We have one with a snowplow and even on that truck they said no. Originally ford made a winter grill cover but discontinued them because of the lack of airflow to the radiators.
You guys want to stay far away from winter covers.
They were necessary back in the day when 18 wheelers had more radiator cooling space than what the thermostate could keep to temp, and would run cold ( below normal temps) going down the road in the winter causing engine problems and loss of heat in the cab.. That's not a problem anymore. There is more than enough heat generated, and still needs to be fully cooled.
Also with today's ultra thin radiator cores, big rigs were experiencing permature failures to the radiators because of cold spots bordering right next to very hot spots (under the cover) on the radiator exchanger causing splits in the cores.
So I wouldn't run one on the smaller diesels because they never have a problem maintaining recommended temperatures.. It boggles my mind that GM sells these things to their customers. I am sure there are a whole bunch of GM trucks running high temperatures and it doesn't do the engine any good.
