International offers winterization tips

| 10/29/2003

International Truck and Engine Corp. has developed several prevention tips for truck owners who want to avoid costly winter maintenance and unforeseen roadside-assistance costs.

International’s Brian Mulshine, manager of service development and marketing, said, “Many northern fleets are accustomed to living in the cold and take proactive measures to protect their trucks. 

“But statistics tell us that many of the vehicles requiring roadside assistance during the winter months are those that are maintained in states with warmer climates, so customers operating in warmer climates have to remember that even though they may not go everywhere, their trucks do.”

Under-Hood Inspection:
