Editor’s Note: Tow Times maintenance editor A.P. McDonald provides tow truck winter-proofing tips, Alaskan-style, in the Tow Times October 2012 issue. Although you may not operate in minus-50-degree temperatures, these tips can be helpful to keep your fleet going strong this winter. Here’s an excerpt from his article. 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 manufacturer’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.
