Information:
Table 4 is an example for using the equation that is in Table 3.
Table 4
Example of the Equation for the Addition of Cat SCA To Water For Maintenance
Total Volume of the Cooling System (V) Multiplication
Factor Amount of Cat SCA that is Required (X)
946 L
(250 US gal) × 0.023 22 L
(6 US gal) Note: Specific engine applications may require maintenance practices to be periodically evaluated to maintain the engine cooling system properly.Cleaning the System of Heavy-Duty Coolant/Antifreeze
Before Cat SCA can be effective, the cooling system must be free from rust, scale, and other deposits. Preventive cleaning helps avoid downtime caused by expensive out-of-service cleaning required for extremelydirty and neglected cooling systems.Cat Cooling System Cleaners
Dissolves or depresses mineral scales, corrosion products, light oil contaminations, and sludges
Cleans the cooling system after used coolant is drained or before the cooling system is filled with new coolant
Cleans the cooling system whenever the coolant is contaminated or whenever the coolant is foaming
The “Standard” version of the Cat Cooling System Cleaners clean the cooling system while still in service.
Reduces downtime and cleaning costs
Helps avoid costly repairs from pitting and other internal problems caused by improper cooling system maintenance
Can be used with glycol-based antifreeze
For the recommended service interval, refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for your engine.Cat Standard Cooling System Cleaners are designed to clean the cooling system of harmful scale and corrosion without removing the engine from service. The cleaners, both “Standard” and “Quick Flush” can be used in all Cat engine cooling systems. Consult your Cat dealer for part numbers.Note: These cleaners must not be used in systems that have been neglected or that have heavy scale buildup. These systems require a stronger commercial solvent that is available from local distributors.Prior to performing a cleaning of the cooling system, take a 1-liter (1-quart) sample of coolant from the engine while in operation into a clear container. Take the sample shortly after start-up while the coolant is not yet hot. The coolant should be adequately mixed by the water pump. Allow the sample
