Coolant Analysis

Supporting Efficient Cooling and Equipment Protection

Coolants play an essential role in controlling operating temperatures and protecting cooling systems. Their condition affects heat transfer, corrosion protection, and resistance to freezing and boiling. Regular coolant analysis helps identify changes in fluid quality and supports timely maintenance decisions.

ETLCO’s Oil & Gas Laboratory provides coolant testing services for automotive engines, industrial machinery, and HVAC systems. Our analysis helps clients assess coolant condition, evaluate key performance properties, and determine whether further investigation or corrective action is required.

Our Coolant Testing Capabilities

ETLCO offers testing of key coolant properties, including:

• Appearance and Color: Examination of visual condition to identify discoloration, cloudiness, or visible contamination.

• Freezing Point: Assessment of the coolant’s protection against freezing.

• pH: Measurement of acidity or alkalinity to support evaluation of coolant condition and corrosion protection.

• Conductivity: Measurement of electrical conductivity to help identify changes in dissolved ionic content.

• Boiling Point: Evaluation of boiling characteristics relevant to high-temperature operation.

Testing requirements can be tailored to the coolant type, system application, and applicable specifications.

Applications

Our coolant analysis services support a range of systems and operating environments:

• Automotive and heavy-duty engine cooling systems.

• Industrial machinery and process cooling circuits.

• Heating, ventilation, and air-conditioning systems.

• Routine preventive maintenance and coolant condition monitoring.

• Investigations into overheating, suspected contamination, or changes in coolant performance.

Benefits of Regular Coolant Analysis

Routine testing provides information that helps clients:

• Monitor coolant condition over time.

• Identify changes that may affect cooling performance.

• Support investigations into corrosion and contamination.

• Make informed coolant replacement and maintenance decisions.

• Reduce the risk of cooling-related equipment damage and unplanned downtime.
