Fuels, Lubricants, and Coolant/Operating in Tropical Conditions OPERATING IN TROPICAL CONDITIONS Always use a recommended glycol base engine coolant, even when operating in geographical areas where freeze protection is not required. IMPORTANT: Never use water as the engine coolant without an initial charge of supplemental coolant additives. Using water alone will cause severe corrosion and pitting damage to vital engine parts. Drain system and refill cooling system as specified in your vehicle operator’s manual. Only when no glycol base engine coolant (antifreeze) is available, use distilled, deionized, or demineralized water meeting the quality specifications on the previous page.
Add to the water an initial charge of supplemental coolant additives, such as John Deere Liquid Coolant Conditioner or equivalent. The recommended concentration of John Deere Liquid Coolant Conditioner must be doubled to 6% (60 mL per Liter of cooling system capacity) by volume when used with water only (no antifreeze). Double other manufacturer’s recommended concentration. 02 11 RG,COOL6,CTM -19-23FEB95 CTM42 (24MAR95) 02-11 6076 Diesel Engines—S.N. (500000— ) 160101 PN=30
