Information:
Use Caterpillar Antifreeze or any low silicate (ethylene or propylene glycol) antifreeze that meets ASTM D4985 requirements. Most commercial antifreezes are formulated for gasoline engine applications and have high silicate content. Caterpillar Antifreeze is formulated with a low silicate content and the proper coolant additives for heavy duty diesel engines.Caterpillar Antifreeze is available through your Caterpillar dealer in quantities that follow. Adding pure undiluted antifreeze as a makeup solution for cooling system top-off is an unacceptable practice. Add antifreeze premixed with acceptable water to the same freeze protection as your cooling system. Use the Antifreeze Concentration chart to assist in determining the concentration of Caterpillar Antifreeze to use. Check the coolant solution frequently in cold weather for glycol concentration with the 5P0957 or 5P3514 Coolant Tester (for Caterpillar products) to ensure adequate freeze protection. The testers are identical except temperature scales (°C or °F) and give immediate accurate readings for antifreeze/coolants that contain ethylene or propylene glycol. Both testers are available at your Caterpillar dealer.
If propylene glycol based antifreeze is used, DO NOT allow concentration greater than a 60/40 antifreeze to water mixture. The measurement of freeze protection must be made with a refractive-type tester (5P0957 or 5P3514) rather than the hydrometer-type tester commercially available. The hydrometer-type tester can be used to test ethylene glycol based antifreeze.
Supplemental Coolant Additive (Conditioner or Inhibitor)
The cooling system MUST contain supplemental coolant additives (conditioner or inhibitor) to control corrosion, cavitation and deposits. It is also necessary to prevent rust, scale, pitting and/or corrosion of engine parts contacted by coolant. The cooling system should be protected with a minimum of three percent concentration at all times, regardless of the concentration of antifreeze. Use supplemental coolant additive liquid OR an element (if equipped) to maintain a three to six percent concentration in the cooling system. Supplemental Coolant Additive must be used with propylene glycol or ethylene glycol antifreeze at the same concentration.
Never use antifreeze/water coolant only, in Caterpillar engines without supplemental coolant additive regardless of antifreeze concentration.Caterpillar or other manufacturer's products can be used as the supplemental coolant additive. DO NOT mix Caterpillar Supplemental Coolant Additive (Conditioner) liquid or elements with the other commercial products available; select a cooling system treatment and use it exclusively.Excessive concentration of supplemental coolant additive can form deposits which may cause engine damage, reduce the engine's heat transfer characteristics and could also accelerate water pump seal wear.
Use the 8T5296 Test Kit to check and monitor the SCA concentration for antifreeze/water coolant mixture. The Caterpillar 8T5296 Test Kit checks for concentration of nitrates in the coolant solution. Some other manufacturers' supplemental coolant additive (SCA) are phosphate based and the 8T5296 Test Kit will NOT provide accurate results. Caterpillar recommends that their test kit be used to check coolant solution concentration.If other than Caterpillar products are used as the supplemental coolant additive, follow the manufacturers' recommendation for cooling system treatment and test evaluation. Commercial supplemental coolant additive products must contain silicates and a minimum of 70 gr/U.S. gallon (1200 ppm)
