Installation Notes
- Inspect the tensioner, idlers, water pump and camshaft pulleys before installation.
- Set the timing marks and belt tension according to the correct engine procedure.

Important: A 178-tooth count alone does not guarantee fitment. Confirm the engine generation, belt width, tooth profile, pulley arrangement and HKS part number before ordering. Incorrect timing-belt installation or tension can cause severe engine damage, so fitting should be completed by a suitably qualified technician.
