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, SEBU6251, "Cat Commercial 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
