Liquid Cooling System NOTE: Debris in the engine com- partment or packed between the cool- ing fins of the radiator can reduce cooling capability. Using a garden hose, wash the radiator to remove any debris preventing air flow. NOTE: Use a good quality, biode- gradable glycol-based, automotive- type antifreeze. ! WARNING Never check the coolant level when the engine is hot or the cooling sys- tem is under pressure. CAUTION CAUTION Arctic Cat does not recommend using a pressure washer to clean the radiator core. The pressure may bend or flatten the fins causing restricted air flow, and electrical components on the radiator could be damaged.
Use only a garden hose with spray nozzle at normal tap pressure. After operating the vehicle for the ini- tial 5-10 minutes, stop the engine, allow the engine to cool down, and check the coolant level. Add coolant as necessary. Oil Cooler (1000) NOTE: Dirt and debris must be cleaned from the cooling fins regularly to ensure proper engine oil cooling. The cooling system capacity can be found in the specification chart. The cooling sys- tem should be inspected daily for leakage and damage. If leakage or damage is detected, take the vehicle to an authorized Arctic Cat dealer for service. Also, the cool- ant level should be checked periodically.
CAUTION Continued operation of the ATV with high engine temperature may result in engine damage or premature wear. CAUTION Continued operation of the vehicle with high engine temperature may result in engine damage or premature wear. NOTE: High engine RPM, low vehi- cle speed, or heavy load can raise engine temperature. Decreasing engine RPM, reducing load, and selecting an appropriate transmis- sion gear can lower the temperature. NOTE: High engine RPM, low vehi- cle speed, or heavy load can raise engine temperature. Decreasing engine RPM, reducing load, and selecting an appropriate transmis- sion gear can lower the temperature.
Shock Absorbers Each shock absorber should be visibly checked weekly for excessive fluid leak- age (some seal leakage may be observed but it does not indicate the shock is in need of replacement), cracks or breaks in the lower case, or a bent shock rod. If any one of these conditions is detected, replacement is necessary. When filling the cooling system, use a coolant/water mixture which will satisfy the coldest anticipated weather conditions of the area in accordance with the coolant manufacturer’s recommendations. NOTE: When the vehicle is operated in extremely cold weather (-23° C/-10° F or colder), a small amount of leakage may be present.
Unless the leakage is excessive, replacement is not necessary. While the cooling system is being filled, air pockets may develop; therefore, remove the bleed plug on the coolant pipe at the front of the engine allowing trapped air to escape. When pure coolant (no air) flows from the bleed hole, install the bleed plug, tighten securely, and then fill the cooling system to the bottom of the stand pipe in the radiator neck. Run the engine for five minutes after the ini- tial fill; then shut off the engine and recheck coolant level. This vehicle is equipped with adjustable shock absorbers in the front and rear to allow for different driving and loading conditions. 39
