Cooling System concentration and corrosion inhibitor content as the original coolant in the cooling system. Never add 100% antifreeze to the cooling system. Always dilute antifreeze to the correct concentration based on freeze protection prior to adding it to the cooling system. Adding or using 100% antifreeze in a cooling system may result in cooling system plugging and overheating problems. NOTE: If frequent topping up is necessary and there are not visible signs of coolant leaks when the engine is cold, check for leaks with the engine operating at normal operating temperature. WARNING! Do not remove the radiator cap on a hot engine. It can cause scalding coolant to spray out and you could be burned. If the engine has been operated within the last 30 minutes, be very careful in removing the radiator cap. • Protect face, hands, and arms against escaping fluid and steam by covering the cap with a large, thick rag. Preventive Maintenance • Carefully and slowly turn cap (on expansion surge tank) one quarter of a turn to allow excess pressure to escape before completely removing cap. If you see any steam or coolant escaping, do not even try to remove it until the radiator cools down. If you see nothing escaping, still remove the cap very slowly and carefully. Be ready to back off if any steam or coolant begins to escape. WARNING! Handle coolant and antifreeze carefully. Ethylene glycol antifreeze is poisonous. Store in original fluid container only, and always keep out of reach of children. • Also, never remove the cap on the surge tank while the engine is still hot. Wait until the coolant temperature is below 120°F (50°C). Scalding steam and fluid under pressure may escape and cause serious personal injuries. WARNING! Do not work near the fan with the engine running. The engine fan can engage at any time without warning. Anyone near the fan when it turns on could be seriously injured. Before turning on the ignition, be sure that no one is near the fan. – 146 – PB1318 3/01 Model 330
