Ensure optimal engine cooling with detailed coolant service steps. Our guide provides templates and KPIs to prevent overheating and extend engine life in heavy fleets.
Follow structured steps to maintain cooling system efficiency.
Coolant service steps are a systematic process to maintain engine coolant levels and quality, ensuring performance under Cab Safety Items in heavy vehicles.
This includes flushing old coolant, checking for leaks, and adding the correct coolant type, aligning with Lubrication Route Map for integrated maintenance.
| Step | Action | Frequency |
|---|---|---|
| 1. Inspection | Check Levels | Monthly |
| 2. Flushing | Remove Old Coolant | Every 2 Years | 3. Refill | Add New Coolant | As Needed |
| 4. Leak Test | Pressure Test | Annually |
| 5. Monitor | Check Temperature | Continuous |

Service every 2 years or 30,000 miles, unless OEM specifies longer-life coolant. Increase checks before extreme seasons using the Seasonal Prep Checklist to verify freeze/boil protection and concentration.
Overheating, sweet odor, visible leaks, rusty/discolored fluid, frequent top-ups, or low reservoir levels. Track trends with the PM KPI Scorecard to spot developing pump, hose, or radiator faults.
Always use OEM-specified chemistry (OAT, HOAT, IAT) and proper mix ratio. Confirm compatibility with elastomers/hoses per Hydraulic Hose Inspection guidance to prevent swelling or leaks.
Yes—level, temperature, and conductivity sensors trigger alerts and WO creation. Validate sensor power/grounds via Electrical Check Protocol to ensure reliable monitoring and fewer manual checks.
3–5 hours covering coolant chemistry, pressure testing, bleeding/air removal, thermostat checks, cap testing, and safety. Include hands-on flushing steps, disposal rules, and documentation checklists for audit readiness.
Use certified recycling facilities; never drain to ground or sewer. Label containers, segregate types, and document volumes per local rules. Follow Coolant Service Steps for compliant handling.
