SOS COOLANT ANALYSIS - PAGE 3

Here's some of the valuable information SOS coolant analysis can determine from your sample.

LAB RESULT	CAUSE	EFFECT
Glycolate and Formate	Overheated coolant (overheated glycol)	Corrosion
High Glycol Level	Too much concentrate added	Poor heat transfer and solder attack
High Lead	Overheated coolant and/or high lead solder used	Solder attack
Low pH with High Iron	Piston blowby or overheated coolant	Severe corrosion
High Copper	Negative stray current or inadequate flushing after cleaning	Ammonia attack of copper radiator/coolant cores
All Metals High with Low Glycolate	Positive stray current	Severe metal attack
Precipitate	High glycol level and/or unacceptable source water	Radiator/cooler tube block or water pump seal leakage
Unacceptable Hardness Level	Unacceptable source water	Precipitation of additives
Oil in Coolant	Cavitation through liners or heat exchanger leak	Engine seizure
High Chlorides	Contamination by source water or atmosphere	Iron corrosion
Low Sebacate	Standard coolant or water added to ELC+	Iron and solder attack
High Silicate and/or High Phosphate	Too much Supplemental Coolant Additive (SCA)*	Water pump seal leakage
Low Glycol Level	Too much water added*	Cavitation, corrosion, reduced freeze point
Low Nitrite and/or High Iron	Not enough SCA added*	Poor heat transfer and solder attack
High Aluminum	Overheated coolant or low SCA*	Aluminum attack
+ Applies only to CAT Entended Life Coolant (ELC) * Applies to Standard Diesel Antifreeze/Coolant(IDEA)
