Cold temperatures, tight delivery schedules, and long idle times make winter one of the toughest seasons for diesel engines. A single weak battery, frozen DEF line, or cracked coolant hose can take a truck off the road — and every hour down means lost revenue.
At STS Truck Services, we help fleets stay ahead of winter breakdowns with proactive inspections, expert diagnostics, and the right parts on hand to keep you moving.
Common Cold-Weather Trouble Spots:
- Frozen DEF lines and fuel filter icing
- Hard starts and slow cranks from weak batteries
- Cracked hoses or degraded coolant flow
- Overheating after cold starts
- Plugged fuel filters or untreated fuel issues
Our Winterization Service Includes:
✔ Coolant freeze-point testing
✔ Battery health and terminal inspection
✔ Block heater and glow plug checks
✔ Fuel system inspection and anti-gel treatment
✔ Belt, clamp, and hose replacement (as needed)
✔ Optional lighter-weight oil for extreme temps
Bonus Tips for Drivers:
- Add anti-gel additive with every fuel fill below 20°F
- Keep fuel tanks at least half full overnight
- Let engines idle and warm before heavy load operation
When you prevent a failure before it happens, you save more than just a repair bill — you protect uptime, reputation, and customer trust.
Schedule your winter prep today and keep your trucks ready for whatever the season brings.
