MAINTENANCE n Foam Oil Breather Element The foam oil breather element absorbs small amounts of liquid to protect sensors within the intake system from damage due to oil ingestion. Check the element before each ride. Clean or replace the breather element at each engine oil change. Clean the element if the snowmobile has been tipped on its left side three times, either during service or while riding, as oil may leak into the element. NOTICE: Operating the snowmobile with a clogged foam oil breather element can result in severe engine damage. Always clean or replace the element as recommended. The foam oil breather element is located inside the airbox. 1. Open the hood. 2. Release the airbox cover retaining clips and remove the cover. 3. Remove the foam breather element. 4. Wash the foam element in soapy water, then rinse thoroughly and let dry. Element Tip: If soap and water are not readily available, remove as much liquid as possible by pressing the foam element in paper towels or a similar absorbent material. 5. Reinstall the dry foam element, or install a new foam element. Tip: Always replace a foam element that is brittle, cracked, crumbling or otherwise damaged. For best performance, routinely replace the foam element with every other engine oil change. 6. Reinstall the airbox cover. Secure all retaining clips. 100
