Cooling system failures are responsible for nearly 40% of all engine-related downtime in commercial fleets. From radiator leaks and thermostat malfunctions to contaminated coolant and failing water pumps, these issues don't just cause breakdowns — they lead to catastrophic engine damage costing upwards of $25,000 per incident in repairs and lost revenue. The good news? Nearly all cooling system failures are preventable with a structured maintenance workflow. Oxmaint's Asset Master provides fleet maintenance teams with a complete digital framework to track every cooling component, automate preventive maintenance schedules, and catch problems before they strand vehicles on the roadside.
Cooling Failures
Major Breakdown
Proper PM
Why Cooling Systems Fail — And What It Costs You
Unplanned Overheating
Low coolant levels, clogged radiators, and thermostat failures cause sudden breakdowns that sideline vehicles for days and cost thousands in emergency repairs.
Scattered Records
Coolant flush schedules, inspection logs, and repair histories spread across spreadsheets make it impossible to track component health or predict failures.
Missed Service Intervals
Without automated triggers based on mileage, hours, or time, critical maintenance like coolant flushes and hose replacements falls through the cracks.
