Coolant Analysis

The Benefits of Coolant Analysis There’s more to coolant analysis than testing coolant formulations — it’s about identifying problems within the cooling system that can be detrimental to engine and lubrication system performance and lead to premature engine failure. Coolant analysis can detect:

• CavitationCorrosion

• AirLeaks

• GlycolDegradation/Overheating

• CavitationErosion

• CombustionGasLeaks

• AcidFormation

• Contamination

• Electrolysis

Four Goals of Coolant Analysis 1 – Preventive MaintenanceCoolant testing and analysis can:

• Determinethecoolant’ssuitabilityforcontinueduse

• Identifycoolantmixing

• Measureadditiveslevelsforadequatemetalprotection

• Identifyscaleoracid-formingcontaminants

• Determineappropriatemaintenance–coolant replenished or full drain and replacement

2 – Predictive MaintenanceRegular testing helps in predicting impending failures by identifying abnormalities and trends in sample results indicativeofoperationalissueswithinthecoolingsystem.

3 – Life Cycle ManagementCoolant analysis is just as powerful as oil analysis in identifying areasforimprovementinequipmentoperationspracticesandmaintenance procedures.

4 – Component Failure IdentificationTesting can identify engine or cooling system component failuressuchasblownheadgaskets,EGRcoolerfailures,electrolysis,defectivepressurecapsorpluggedcoolantlines.
