Cold snaps in PA can strand a truck fast. Work through this short winter-prep list before temps drop so you avoid gelled fuel, dead batteries, or frozen air systems.

1. Fuel Treatment & Storage

   Switch to winter-grade diesel early, add anti-gel at every fill when temps < 20°F, and keep tanks above half to reduce condensation. Carry a bottle of emergency de-gel in the cab.

2. Batteries & Charging

   Load-test all batteries, clean and coat terminals, verify alternator output under load, and inspect starter draw so cold cranking stays strong.

3. Air System & Dryers

   Replace desiccant cartridges, drain tanks, check purge valve, and consider air-line antifreeze where allowed. Moisture in the system is the biggest winter quitter.

4. Cooling & Heaters

   Test coolant freeze protection, inspect hoses, verify cab heater and defroster, and confirm block heater operation. For APUs, service the coolant loop and glow plugs.

5. Tires, Wipers, Visibility

   Check tread depth and inflation, carry chains where required, replace wipers, fill winter washer fluid, and clean lights/reflectors for dark commutes.

6. Driver Winter Kit

   Stock gloves, headlamp, traction mats, blanket, high-calorie snacks, water, scraper, spare fuses, and phone power banks in a labeled bin.
