The VCT phaser varies camshaft timing in response to oil pressure exerted on either side of the vanes.
CAUTION: Only use hand tools to remove the camshaft phaser sprocket assembly or damage may
occur to the camshaft or camshaft phaser unit.
CAUTION: Always install a new bolt and washer whenever the VCT phasers are loosened. The base
part number is 6279. The same part number is used for both sides.
NOTE: These bolts are one-time torque only and are available separately or as part of the phaser replacement kit.
CAUTION: Handle the cam and phaser carefully. Damage will occur if dropped or mishandled.
