MAINTENANCE Spark Plugs It's very important to use the correct spark plug for your snowmobile. A spark plug with a heat range too high will cause engine damage. A spark plug with a heat range too low will cause excessive fouling and engine malfunctioning. In selecting a spark plug heat range for production, a manufacturer assumes that the engine will be operated under extreme heavy duty conditions and selects a spark plug that will protect the engine from internal damage if the purchaser actually does operate the engine in this manner. This selection could cause the customer who normally operates the engine under medium or light duty to have spark plug failure. NOTICE: A spark plug with a heat range too high will always cause engine damage if the engine is operated in conditions more severe than intended for that plug. Always use the spark plugs recommended for your snowmobile. Refer to the specifications section beginning on page 104. A new engine can cause temporary spark plug fouling due to the preservative added during the assembly process. Avoid prolonged idle speeds, which cause plug fouling and carbonization. • Use recommended spark plugs with the proper gap. Refer to the specifications section beginning on page 104. • Spark plug torque is 18-22 ft. lbs. (24.4-29.8 Nm). • Always carry spare spark plugs in case of an emergency. NOTICE: Using non-recommended spark plugs can result in serious engine damage. Always use POLARIS-recommended spark plugs. 69
