Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns smoothly.
For the following operations, perform steps in the reverse order of removal.
NOTE: If hydraulic pressure inside chain tensioner drops after removal/installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.
