Winter takes its toll on all types of vehicles, especially commercial trucks when heavily used. As a result, it’s important to perform routine maintenance; you’ll avoid emergency semi-truck repairs and costly downtime. Here are a few tips for keeping fleet vehicles operating at peak condition during the coldest months of the year. 

A Guide to Winter Truck Maintenance 

1. Replace the Fuel & Oil  

In cold climates, it’s common for commercial truck drivers to notice a decrease in fuel-efficiency or encounter a vehicle that won’t start. This is because regular diesel fuel contains paraffin molecules that stick together in frigid temperatures. Replace this fuel with a winter blend that is designed to hold up in harsh conditions. The oil should also be replaced with one that has an optimal viscosity level for driving in winter. Thicker oils have a hard time circulating through engines when it gets cold, resulting in excessive wear and the need for semi-truck repairs. 

2. Inspect the Tires 

Inspecting the tread and pressure of all truck tires is essential for preventing flats and blowouts in winter. Dropping temperatures can cause a considerable fluctuation in tire pressure, which can be dangerous. Any tires showing signs of wear or damage should be replaced right away. Even if they still look like they’re in good condition, switch them out for tires that are specifically designed to have better traction in the snow. 

3. Test the Battery

Vehicle batteries have a high risk of failure during cold weather because more power is required to start the engine. Regularly testing the strength of a truck’s battery will allow you to replace it before it fails. Also, check for loose wiring that could keep a battery from holding a charge and functioning correctly. 

4. Check the Belts & Hoses 

Freezing temperatures can weaken and crack a truck’s belts and hoses. This affects engine performance and creates a safety hazard. Carefully check each belt for evidence of fraying or cracking, and look at every hose to see if there are any leaks or they feel brittle. If so, schedule semi-truck repairs to have them replaced immediately.
