Installation Notes and Tips

Verify the vehicle year, model, and air conditioning application before ordering. Confirm the belt routing and pulley direction match the original tensioner, since this unit is counter clockwise and uses a flat 65 mm pulley. Inspect the serpentine belt and adjacent pulleys during service so worn components do not shorten the life of the replacement tensioner.
