Glycol

Coolant system leakage is one of the most serious hazards for any lubricating system. Glycol from antifreeze breaks down at normal engine temperatures and forms sludge and deposits. Water in the coolant reduces lubricity and can cause corrosion and premature wear.

An analysis for water by itself may not be reliable enough since engine temperatures will vaporize low levels of water. Emission spectroscopy such as with the Spectroil M is used to detect the existence of antifreeze in a lubricant through the detection and quantification of sodium, boron and/or potassium from the antifreeze additive. Infrared spectroscopy with the Spectro FTIR or FluidScan can also be applied to detect antifreeze contamination.
