Prepare your heavy fleet for winter with our coolant service guide. Follow simple steps and track KPIs to prevent freezing, reduce downtime, and ensure engine reliability in harsh conditions.
Ensure your fleet’s coolant system prevents freezing and overheating.
Proper coolant maintenance prevents engine freezing, corrosion, and overheating, ensuring fleet reliability and reducing costly repairs during winter.
Cold temperatures can freeze coolant, damaging radiators and engine blocks, while improper coolant mixtures lead to corrosion or overheating. A structured coolant service plan, integrated with your seasonal prep checklist, keeps your fleet operational and efficient.
| Component | Issue Frequency | Impact |
|---|---|---|
| Coolant Fluid | 35% | Freezing or contamination |
| Radiator | 30% | Clogs or leaks |
| Hoses | 20% | Cracks or bursts |
| Thermostat | 15% | Overheating risk |
Monitor these with your PM KPI scorecard to prevent failures.

Answers to optimize your fleet’s cooling system maintenance
Coolant should be checked monthly as part of Schedule B and flushed every 2 years or per OEM guidelines. Winter checks are critical—use PM KPI scorecard to track intervals.
Use a 50/50 antifreeze-water mix with extended-life coolant (OAT or HOAT) per OEM specs to prevent freezing and corrosion. Verify with seasonal prep checklist for recommendations.
Look for low coolant levels, cloudy fluid, leaks, or overheating warnings during cab safety items checks. Log issues in reporting KPIs for tracking.
Skipping coolant service risks freezing and engine damage in cold weather. Regular checks per Schedule A and full service per Schedule C are essential for reliability.
