pH
Proper pH levels re needed for optimum corrosion inhibitor performance
NITRITES
Excessive nitrite levels can lead to solder corrosion
FREEZE POINT
a chemical change in the base oil molecules under elevated temperature.
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, oil cooler, after cooler, 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 testingEAS – Basic Coolant
PEAS – Advance Coolant
