Testing the engine coolant is important to ensure that the engine is protected from internal cavitation and corrosion. The analysis also tests the ability of the coolant to protect the engine from boiling and freezing. S·O·S Coolant Analysis can be done at your AVSpare dealer. AVSpare S·O·S Coolant Analysis is the best way to monitor the condition of your coolant and your cooling system. S·O·S Coolant Analysis is a program that is based on periodic samples.

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 designated pump for oil sampling and a designated 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 a coolant analysis (Level 2) at 500 service hours for new systems, for refilled systems, or for converted systems that use Cat Extended Life Coolant (ELC) or use Cat Diesel Engine Antifreeze/Coolant (DEAC). This 500 hour check will also check for any residual cleaner that may have contaminated the system.
Recommended Interval for S·O·S Coolant Sample
Perform a coolant analysis (Level 1) at every 500 service hour interval. Perform a coolant analysis (Level 2) annually, or perform a coolant analysis (Level 2) when a problem is identified by a coolant analysis (Level 1).
Note: Check the standard coolant's Supplemental Coolant Additive (SCA) at every oil change.
S·O·S 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 analysis
The results are reported, and appropriate recommendations are made.
S·O·S 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 inside of the cooling system.
The S·O·S Coolant Analysis has the following features:
- Full coolant analysis (Level 1)
- Identification of the source of metal corrosion and of contaminants
- Water hardness
- Identification of buildup of the impurities that cause corrosion
- Identification of buildup of the impurities that cause scaling
The results are reported, and appropriate recommendations are made.
