ESSENTIAL WINTER MAINTENANCE TIPS FOR TRUCK DRIVERS

Kenworth is here to keep you safe and keep you going. That’s why we’ve built a strong network of hundreds of authorized dealerships throughout North America, ready to support you wherever you go this winter. These practical solutions from Kenworth Parts & Service will help you to winterize your fleet :

1. Batteries : Batteries can lose up to 35% of their power in freezing temps. Inspect your batteries for signs of corrosion, leakage, or damage.  

2. Block Heaters : In cold climates, diesel won’t be frozen solid, but it will not be in liquid form. Use block heaters if you plan to park your vehicles in extremely cold weather.

3. Insulated Tote Blankets : Diesel Exhaust Fluid (DEF) begins crystalizing at 12°F (−11°C). To help prevent freezing, consider using an insulated tote blanket.

4. Tire Chains : Inspect tire chains before winter.

5. Winter Grille Covers : Winterizing your front grilles makes start-ups easy, keeps the engine warm and helps prevent diesel fuel from gelling.

6. Windshield Wipers : Replace wipers regularly to clear snow and aid visibility.

7.  Winter Windshield Wiper Fluid : Top off your windshield wiper fluid and keep extra on-hand for when needed.

8. Fuel Filters : Inspect and replace fuel filters. Contaminated filters clog and trap fuel which can put a vehicle out of service.

9. Extra Bulbs : Make sure all electrical systems are fully operational.

10. Fuel Caps : A secure fuel cap prevents loss of fuel pressure and prevents debris from entering fuel tanks.

When adding a winter grille cover, remember there still needs to be proper air flow to your engine. When parked, make sure the nose of your vehicle is away from the wind. Check your winter grille cover to make sure it is secure, so it does not blow around.
