COOLANT TESTING - Coolant Testing

Coolant Testing Services

pH

Proper pH levels re needed for optimum corrosion inhibitor performance

NITRITES

Excessive nitrite levels can lead to solder corrosion

FREEZE POINT

POINT-High glycol can cause additive dropout and decrease in coolant life

CONTAMINTION

Lubrication of pump Injector Designates any outside contamination (Trace, Moderate, Heavy)

Corrosion occurs when buffers are no longer able to counter acid formation due to thermal degradation. Typical Corrosion Product Sources

Fe

liner, water pump, cylinder block/head

Al

radiator tanks, coolant elbows, piping, spacer plates, thermostat housings

Cu

radiator, oil cooler, after cooler, heater core

Pb

radiator solder, oil cooler, aftercooler, heater core

Si, B, Mo and P are inhibitors present in coolants for metal protection and pH control. Inhibitors present are dependent upon the coolant formulation.

Ca & Mg Contaminants present in an engine coolant will form scale on hot metal surfaces

Petrolab offers two packages for coolant testing

PEAS – Basic Coolant

PEAS – Advance Coolant
