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:

n Cavitation Corrosion

n Air Leaks

n Glycol Degradation/Overheating

n Cavitation Erosion

n Combustion Gas Leaks

n Acid Formation

n Contamination

n Electrolysis

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

n Determine the coolant’s suitability for continued use

n Identify coolant mixing

n Measure additives levels for adequate metal protection

n Identify scale or acid-forming contaminants

n Determine whether the coolant can be replenished or drained and replaced

2 – Predictive MaintenanceRegular testing helps in predicting impending failures by identifying abnormalities and trends in sample results indicative of operational issues within the cooling system.

3 – Life Cycle ManagementCoolant analysis is just as powerful as oil analysis in identifying areas for improvement in equipment operations practices and maintenance procedures.

4 – Component Failure IdentificationTesting can identify engine or cooling system component failures such as blown head gaskets, EGR cooler failures, electrolysis, defective pressure caps or plugged coolant lines.
