Coolant Analysis


Coolant Analysis – Why Test Your Cooling System?

Bureau Veritas’s coolant analysis program takes the guesswork out of cooling system maintenance. Coolant testing at regularly scheduled maintenance intervals can identify system problems before catastrophic engine failure occurs, which saves time and money in multiple ways:

  • Reduces downtime
  • Decreases engine and cooling system repairs
  • Eliminates unnecessary coolant drains
  • Lessens coolant replacement and disposal costs

Coolant Analysis has four goals:

Goal #1 – Preventive Maintenance

Coolant testing and analysis monitors changes in coolant properties due to chemical reactions occurring within the cooling system before they escalate to failure. It can determine if:

  • the coolant is suitable for continued use
  • coolant mixing has occurred
  • additives depletion is compromising metal protection
  • contaminants are present that can cause scale or acid formation
  • coolant should be removed and replenished with new coolant

Goal #2 – Predictive Maintenance

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

Goal #3 – Life Cycle Management

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

Goal #4 – 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.
