IMPORTANT BENEFITS & GOALS OF COOLANT ANALYSIS

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:

• Cavitation corrosion

• Air leaks

• Glycol degradation / overheating

• Cavitation erosion

• Combustion gas leaks

• Acid formation

• Contamination

• Electrolysis
  

Goals of Coolant Analysis 

Preventive Maintenance

Coolant testing and analysis can:

• Determine a coolant’s suitability for continued use

• Identify coolant mixing

• Measure additives levels for adequate metal protection

• Identify scale or acid-forming contaminants

• Determine appropriate maintenance – replenish the coolant or full drain and replacement

Predictive Maintenance

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

Life-Cycle Management

Coolant analysis is just as powerful as oil analysis in identifying areas for improvement in equipment operations and maintenance procedures.

Component Failure Identification

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