Shop Mechanic's Tuning Advice: When installing a fresh CVT drive belt, always inspect your variator roller weights and rear clutch assembly pads for wear or glazing. To optimize performance and ensure maximum transmission belt longevity, we recommend thoroughly wiping down the pulley faces with a brake cleaner solvent to clear out old rubber dust and scaling deposits prior to final belt seating.
