Winter Service Checklist for Your Fleet

Frosted tree in winter

Winter is just around the corner, and the colder temperatures present unique challenges for truck maintenance. Is your fleet ready to weather any storm? In this edition of the Papé Kenworth blog, let’s take a look at how you can prepare for the seasonal changes ahead while completing routine maintenance for your fleet.

When servicing your fleet for the winter season, what steps should you take? Our experts have put together a comprehensive checklist.

#1 Check the Battery

As temperatures drop, batteries become more finicky. Here at Papé Kenworth, our service team sees the most battery issues during the colder months. Test your truck batteries and be sure the battery terminals are clean. This is even more vital for electric-powered trucks! If you think you might need to order a replacement battery, but aren’t totally sure, it’s best to play it safe; with parts shortage issues, you want to be proactive and prevent any downtime.

#2 Change the Coolant

Replace the coolant filter. Test the coolant to be sure all is working properly. Antifreeze can evaporate over time, so be sure to check the last date of your coolant replacement. Coolant should be replaced at least once every 2 years, so be sure to stay on top of this to avoid engine overheating.

#3 Fuel Changes

If conditions are going to drop to 10 degrees fahrenheit, you may want to switch to a different type of diesel fuel. Also, be sure to replace fuel filters. Drain the water separator regularly throughout the winter so that it doesn’t freeze.

#4 Check Tires

Having enough tread is essential during the winter. Slippery and icy conditions lead to sliding and driving hazards. Check your tire tread to ensure proper tire traction. Remember: tire pressure drops in cold temperatures, so be sure to regularly fill your tires and ensure optimal pressure. Consider tire chains for especially wintry conditions–and always have them at the ready.

#5 Clean the Truck

Make sure there is ample visibility by keeping windows and windshields extremely clean. Check windshield wiper fluid levels and be sure to use low temperature fluid so that it doesn’t freeze.

#6 Check Your Heating System

Be sure your heat and defroster are working properly.

#7 Check the Engine

Check the engine and perform routine maintenance to be sure and identify issues. Check all electrical connections specific to the engine. Check engine belts and hoses, and replace them as necessary (the earlier, the better!).

#8 Safety First

Always be ready to take action should you face issues while on the road. Be sure your fleet is equipped with roadside assistance and emergency kits. Ensure that all drivers have spare fuel filters, fuel tank conditioner/treatment, and anti-gel products with them while traveling. If you need help, you can even call Kenworth PremierCare Roadside Assistance Call Center after hours by calling 1-800-592-7747; just another reason you can trust Papé 24/7.
