Information:
Do not use the same vacuum sampling pump for extracting oil samples that is used for extracting coolant samples.A small residue of either type sample may remain in the pump and may cause a false positive analysis for the sample being taken.Always use a separate pump for oil sampling and a separate pump for coolant sampling.Failure to do so may cause a false analysis which could lead to customer and dealer concerns.
New Systems, Refilled Systems, and Converted Systems
Perform an S O S coolant analysis (Level 2) at the following maintenance intervals.
Initial 500 service hours
Every Year or every 2000 hours, whichever comes firstPerform this analysis at the interval that occurs first for new systems, for refilled systems, or for converted systems that use Cat ELC (Extended Life Coolant) or use Cat DEAC (Diesel Engine Antifreeze/Coolant). This 500 hour check will also check for any residual cleaner that may have contaminated the system.Recommended Interval for S O S Services Coolant Sample
The following table contains the recommended sampling interval for all coolants that meet Cat EC-1 (Engine Coolant specification - 1). This is also the recommended sampling interval for all conventional heavy-duty coolant/antifreeze.The Level 2 Coolant Analysis should be performed if a problem is suspected or identified.
Table 1
Recommended Interval
Type of Coolant Level 1 Level 2
Cat DEAC
and Conventional Heavy-Duty Coolants Every 250 hours Yearly
Cat ELC
and Commercial EC-1 coolants Optional or every 500 hours Yearly or every 500 hours Note: Check the SCA (Supplemental Coolant Additive) of the conventional coolant at every oil change or at every 250 hours. Perform this check at the interval that occurs first.Refer to your machine OMM for recommendations specific to your machine.S O S Services Coolant Analysis (Level 1)
A coolant analysis (Level 1) is a test of the properties of the coolant.The following properties of the coolant are tested:
Glycol concentration for freeze protection and boil protection
Ability to protect from erosion and corrosion
pH
Conductivity
Visual analysis
Odor analysisThe results are reported, and appropriate recommendations are made.S O S Services Coolant Analysis (Level 2)
A coolant analysis ( Level 2) is a comprehensive chemical evaluation of the coolant. This analysis is also a check of the overall condition of the cooling system.The S O S coolant analysis ( Level 2) has the following features:
Full coolant analysis (Level 1)
Identification of metal corrosion and of contaminants
Identification of buildup of the impurities that cause corrosion
Identification of buildup of the impurities that cause scaling
Determination of the possibility of electrolysis within the cooling system of the engineThe results are reported, and appropriate recommendations are made.For more information on S O S coolant analysis, consult your Caterpillar dealer.
