Installation Notes

A licensed technician or qualified fleet mechanic should perform oil filter service on commercial vehicles.

Position the band wrench squarely around the filter canister before applying torque to prevent slippage and filter damage. Dispose of used oil and filters in accordance with local environmental regulations.
