Special Requirements
Cat C7-C32 Marine Engines with heat exchangers Minimum of 30% glycol is required. 50% Glycol is recommended. Water alone or water with SCA or with ELI is NOT allowed.
Cat diesel engines equipped with air-to-air aftercooling (ATAAC)
Use Only Approved SCAs and ExtendersConventional coolants require the maintenance addition of SCA throughout the expected life of the coolants. Do NOT use an SCA with a coolant unless approved specifically by the coolant supplier. The coolant manufacturer is responsible for ensuring compatibility and acceptable performance.To help ensure expected performance, EC-1 coolants require the one time maintenance addition of an extender at coolant service mid-life. Do not use an extender with a coolant unless the extender has been approved specifically for use by the coolant manufacturer. The coolant manufacturer is responsible for ensuring compatibility and acceptable performance.Failure to follow these recommendations can result in shortened cooling system component life.
Cat ELC can be recycled into conventional coolants.For more information, refer to Special Publication, SEBU7003, "Cat 3600 Series and C280 Series Diesel Engine Fluids Recommendations".S O S Services Coolant Analysis
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 Cat dealer. Cat 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.

Recommended Interval
Type of Coolant Level 1 Level 2
Cat DEAC
Cat SCA
Conventional Heavy-Duty Coolants Every 250 hours Yearly(1)
Cat ELC
Cat ELI
Commercial EC-1 Coolants Optional(1) Yearly(1)
(1) The Level 2 Coolant Analysis should be performed sooner if a problem is suspected or identified.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.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 Cat dealer.Greases
If necessary, choose a single grease, always choose a grease that meets or exceeds the requirements of the most demanding application. Remember that the products
