When the chilly winds of winter start to bite, your truck’s Auxiliary Power Unit (APU) can be your best friend out on the road. But only if it’s in tip-top shape. Nothing ruins a road trip faster than climbing into your cab after a long haul, only to find your heater won’t work, or you’re facing a dead battery. Before freezing temps arrive, it makes sense to give your APU a little TLC with a pre-season checkup—especially if you count on mobile truck repair services to keep things rolling.
Inspect and clean key components
Start by checking all air filters, belts, and hoses for signs of wear, cracks, or grime. Replace damaged parts to prevent unexpected breakdowns when you least want them. Don’t forget to clean any debris from exterior vents and fans, too. Dirty or blocked airflow will reduce your heater’s effectiveness and stress your truck’s APU, which could lead to bigger repairs down the line.
Double-check your coolant and antifreeze levels. Winter means things freeze up quickly if fluids aren’t at the right concentration, and a low coolant system is just asking for icy trouble.

Test electricals and batteries
Give your battery a good once-over by looking for corrosion on the terminals and checking the hold-downs. Look for any warning signs like flickering lights on your control panel—this could mean trouble is brewing in your electrical system. Make sure all wiring is secure and free from wear or fraying.
If you’re relying on mobile service, let the pros test your battery’s charge and inspect system outputs. Mobile techs have diagnostic tools on board to catch issues before they become cold-night breakdowns.
