Timing Drive Components: Removal

WARNING: This page is about a different variant/trim than selected.
CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
CAUTION: The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore, the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
  2. Remove the accessory drive belt. For additional information, refer to ACCESSORY DRIVE - HYBRID .
  3. Remove the valve cover. For additional information, refer to VALVE COVER .
  4. Remove the engine mount. For additional information, refer to ENGINE MOUNT .
    5. CAUTION: Failure to position the No. 1 piston at top dead center (TDC) can result in damage to the engine. Turn the engine in the normal direction of rotation only.
  5. Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at TDC.
    • The hole in the crankshaft pulley should be in the 6 o'clock position.

    6. CAUTION: The special tool 303 - 465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
    NOTE: The camshaft timing slots are offset. If the special tool cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.

    8. NOTE: The special tool will contact the crankshaft and prevent it from turning past TDC. However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position until the timing drive components and crankshaft pulley are installed.
