Installation Notes and Tips

Verify engine code and timing system configuration before installation, since the same model may use different guide components across years. Inspect the timing chain, tensioner, and related valve train parts at the same time, and replace any worn components together to avoid repeat service. Confirm the part number ZG-9-5566 and the INA Global Number 552 0099 100 against the vehicle’s original guide before assembly.
