Test for SCA Or Obtain Level I Analysis
Check the cooling system only after the engine is stopped and cool. Remove the filler cap slowly to relieve pressure. To prevent engine damage, never add cooling system products to an overheated engine. Allow the engine to cool first.The use of Caterpillar SCA will prevent internal damage to the engine, such as liner or block pitting. If the SCA concentration is too low, pitting of the cylinder wall may occur, which can lead to costly engine damage.If the SCA concentration is too high, sludge and mud-like deposits may form in the cooling system. This adversely affects engine performance and can also lead to costly repairs of the engine and cooling system.
The over concentration of a supplemental coolant additive will result in deposits on the higher temperature surfaces of the cooling system and create a barrier that reduces the engine's heat transfer characteristics.Reduced heat transfer could cause cracking of the cylinder head and other high temperature components. Excessive concentrations of additive could also accelerate water pump seal wear.
Use the 4C-9301 Test Kit or use the 8T-5296 Test Kit to check for SCA concentration. Add SCA if the concentration is too low. If the SCA concentration is excessive, drain half the coolant, and replace with the proper water/antifreeze mixture. You may test your coolant SCA concentration OR have the SCA concentration tested as part of a S O S Coolant Analysis (Level I). Obtain Level I AnalysisS O S Coolant Analysis is the best way to monitor the condition of your coolant and your cooling system. Level I: Basic Coolant Maintenance CheckChecks for correct chemical balance for proper heat and corrosion control. Tests for:* glycol* SCA concentrations* pH* conductivityS O S Coolant Analysis reports results and makes recommendations, usually within 24 hours. Consult with your Caterpillar dealer for more information.Add Liquid Supplemental Coolant Additive (SCA)
Only add SCA if required by SCA test results.
Excessive and continuous over concentration of SCA (greater than the recommended 6 percent initial fill), together with antifreeze concentrations greater than 60 percent, can result in deposits on the higher temperature surfaces of the cooling system, accelerated water pump seal wear, and radiator tube blockage, forming a barrier that reduces the engine's heat transfer characteristics. Reduced heat transfer could cause cracking of the cylinder head and other high temperature components.To prevent over inhibiting the engine's cooling system, never use both SCA liquid AND the SCA element (if equipped) at the same time.
1. Loosen the cooling system filler cap slowly to relieve pressure. Remove the cap.2. It may be necessary to drain enough coolant from the cooling system to allow for the addition of the liquid SCA.3. Add liquid SCA according to the requirements for your engine's cooling system capacity. Refer to the Refill Capacities chart in this manual for your engine's cooling system capacity. Refer to the Coolant Specifications in this manual for the Caterpillar SCA Requirements chart.4. Clean the filler cap. Inspect the filler cap gaskets. Replace the cap
