See the October feature article “Winter-proofing Alaskan Style” for more info.
Grille covers are popular in Alaska whether made from cardboard or the commercially made vinyl ones. At below zero temperatures, even a hard working engine benefits from having 80 to 95 percent of its radiator covered. Under-the-hood temperatures become warmer and everything works better at the temperatures for which they are designed. An often-mentioned benefit is that the cab heater is able to work more efficiently and keep the operator more comfortable.
On trucks with turbo air-charge intercoolers, it is important to follow the manufacturerâ€™s recommendations as to the size and location of air inlets in any grill cover, as differential heating and cooling of the air-charge intercooler can cause expensive cracking of the intercooler.
