Belt Size Check: If your vehicle has a 12" or 13" rear wheel, you need a longer belt — typically an 835-20-30 or 842-20-30. Always check the size stamps on your old belt before ordering. Mechanic's Tip: When replacing a worn CVT belt, inspect your variator roller weights and clutch pulleys. Clean belt dust from the housing with brake cleaner. Never use screwdrivers or pry bars to force the belt over pulleys — compress the rear clutch pulley sheave by hand to create the slack needed to slide the belt on safely.
