Supplemental cooling system additive contains alkali. To prevent personal injury, do not drink, avoid contact with the skin and eyes.
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.
SCA is necessary for proper conventional coolant maintenance. Most coolant solutions DO NOT contain sufficient SCA for diesel engine application.
Do not exceed the recommended six percent SCA concentration. 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 liquid 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 liquid SCA or a SCA element (if equipped) to maintain a three to six percent SCA concentration in the coolant. Caterpillar Test Kits check for concentration of nitrites in the coolant solution. Some manufacturers' SCA are phosphate based. Caterpillar Test Kits provide inaccurate results with phosphate based SCA. Commercial SCA products must contain silicates and a minimum of 1200 mg/L or 1200 ppm (70 grains/1 US gal) nitrites. If another manufacturer's SCA is used, use that manufacturer's test kit. Follow the manufacturer's recommendations for cooling system treatment and test evaluation.Test the coolant periodically to monitor SCA levels. Use the 4C-9301 Test Kit to check for Caterpillar SCA concentration. The kit also provides cooling system maintenance recommendations. This kit is specifically for use with Caterpillar SCA's. The 8T-5296 Test Kit can also to check for Caterpillar SCA concentration.The following charts lists the part numbers and quantities of SCA (liquid and solid) available from your Caterpillar dealer. Follow the instructions on the label. Permitted-Water/SCA Coolant
Never use water alone without SCA or inhibited coolant. Water alone is corrosive at engine operating temperatures.
A mixture of water and SCA does not protect against freezing or boiling.
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.
Caterpillar's recommendation for proper coolant is a minimum concentration of 30 percent glycol and 70 percent Acceptable Water and SCA (3 percent of the total mixture). This recommendation will maintain cooling system corrosion protection.
In applications where freeze protection is not required, or where antifreeze is not available, a coolant mixture of Acceptable Water and SCA can be used. A Water/SCA system should maintain a six to eight percent SCA concentration. DO NOT exceed eight percent maximum SCA concentration. SCA concentration levels must be monitored.The 8T-5296 Test Kit can be used to evaluate the SCA concentration in Water/SCA coolant, with the following modifications to label instruction Step 3 and Step 5.STEP 3.
