Supplemental cooling system additive contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.
The cooling system MUST contain supplemental coolant additive (SCA) for proper engine protection, regardless of antifreeze concentration.DO NOT mix Caterpillar SCA or coolant additive elements with another manufacturer's products: select a cooling system treatment and use it exclusively.
Do not exceed the recommended six percent SCA concentration together with antifreeze concentrations greater than 60 percent. Excessive SCA concentration can form deposits on the higher temperature surfaces of the cooling system, reducing the engine's heat transfer characteristics. Reduced heat transfer could cause cracking of the cylinder head and other high temperature components. Excessive SCA concentration could also result in radiator tube blockage, overheating, and/or accelerated water pump seal wear.Never use both SCA and the spin-on element (if equipped) at the same time. The use of those additives together could result in SCA concentration exceeding the recommended six percent maximum.
Use the 8T5296 Test Kit to check for and maintain the concentration level of Caterpillar SCA.
Caterpillar 8T5296 SCA Test Kit. The Caterpillar 8T5296 Test Kit checks for concentration of nitrates in the coolant solution. Some other manufacturers' SCA is phosphate based. The 8T5296 Test Kit provides inaccurate results with phosphate based SCA. Commercial SCA products must contain silicates and a minimum of 70 gr/U.S. gallon (1200 ppm) nitrites. If other manufacturers' SCA is used, also use the SCA manufacturer's test kit. Follow the manufacturer's recommendation for cooling system treatment and test evaluation.The following chart lists the part numbers and quantities of liquid SCA available from your Caterpillar dealer. Follow the instructions on the label. Water-Only Coolant
Caterpillar recommends a minimum concentration of 30 percent antifreeze, deionized or distilled water, and supplemental coolant additive (SCA). However, a coolant mixture of acceptable water and SCA can be used in applications where conditions do not require freeze protection, or where antifreeze is not available.A coolant mixture of water and SCA will cool and provide some protection to engine components, but it will not provide normal engine service life. Antifreeze/water mixtures provide better performance life than water-only coolant.If the engine cooling system is filled with water ONLY, SCA concentration should be maintained at six to eight percent maximum. Do not exceed eight percent maximum concentration. Monitor SCA concentration levels with a SCA test kit.The 8T5296 Test Kit can be used to evaluate the SCA concentration of water-only coolant with the following modifications to Step 3 and Step 5.STEP 3-Add tap water to the vial up to the 20 ml mark.STEP 5-With the defined procedure, the six to eight percent concentration will yield a 20 to 27 drop range. Fewer drops indicate under-concentration of SCA and more drops indicate over-concentration. Adjust the concentration appropriately. If the SCA concentration in your cooling system is greater than the maximum of eight percent: drain some of the coolant, refill the system with acceptable water, and re-test the concentration level.Initial Fill
SCA is pre-mixed in Caterpillar Antifreeze. SCA is not needed for initial
