Coolant Analysis

"An estimated 50% of all engine failures or poor performance incidents are associated with cooling system problems." 

A cooling system has a direct effect on the operation and service life of an engine. Diesel engines are designed to operate at higher temperatures and higher energy levels than in the past. Today’s heavy-duty diesels produce a tremendous amount of power from a small package.

Cooling systems have to absorb more heat with smaller cooling systems and less coolant. A cooling system may also be transferring heat away from turbochargers, transmissions, hydraulic systems and other equipment components

A regular schedule of coolant sampling:

  • Verifies the proper chemistry of your coolant.
  • Diagnoses the condition of your cooling system.
  • Allows you to correct coolant or cooling system problems before costly failures occur.




This involves an extensive chemical evaluation of the coolant.

We measure Percent Glycol to calculate Boiling Point and Freezing Points.

Quantify additives like nitrite, phosphate, borate and silicate to determine if coolant still has protective properties.


Coolant Condition

Identifies foreign impurities and gives the overall condition of the coolant and cooling system.

Check for contamination to determine if anything harmful has entered such as the presence of oil or fuel.

Monitor Chloride and Sulfate to ensure quality water source is used.



Results are interpreted to reveal any major problems or predict future failures and provide recommendations.

Analyze for erosion and corrosion through elemental analysis of Iron, Aluminium, Copper, Lead, Tin and Zinc.

Look for signs of overheating, stray electrical currents and exhaust gas entry.

For example metal corrosion, caused by acidified coolant, due to combustion gas entry, needs immediate repair.
