Fuels, Lubricants and Coolant REPLENISHING SUPPLEMENTAL COOLANT ADDITIVES (SCA’S) BETWEEN COOLANT CHANGES Through time and use, original additives eventually lose their effectiveness and must be recharged with additional supplemental coolant additives available in the form of liquid coolant conditioner. G NOTE: Service intervals listed are a recommended engineering guideline. Refer to your vehicle operator’s manual for a specific service interval. At 600 hours or 1 year service interval, it is recommended to perform a COOLSCAN analysis as described earlier. If COOLSCAN analysis is not available, recharge system per instructions printed on bottle. IMPORTANT:
DO NOT CHANGE the spin-on filter element at the 600 hour or 1 year service interval. If the filter is replaced at this time, the result could be an overcharged system. This could cause “solder bloom” in the radiator because the over concentration of nitrite will attack the solder. Replace the filter only if the entire cooling system is drained and coolant replaced. See ENGINE COOLANT SPECIFICATIONS earlier in this group for proper mixing of coolant ingredients before adding to the cooling system. FLUSHING AND SERVICING COOLING SYSTEM IMPORTANT: ALWAYS maintain coolant at correct level and concentration. DO NOT operate engine without coolant for even a few minutes.
If frequent coolant make-up is required, the glycol concentration should be checked with JT05460 Refractometer to assure that the desired freeze point is maintained. Follow manufacturer’s instructions provided with refractometer. 4/7/95 G-13 AllTractorManuals.com RG6 RG6 262 CAUTION Explosive release of fluids from pressurized cooling system can cause serious burns. Shut off engine. Remove the radiator filler cap only when the cap is cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely. RG62 RG62 61
