Cam Chain Installation

NOTE:
  • Keep the cam chain away from magnetic fields.
  • Before this procedure, check that the variable valve timing control (VTC) actuator is locked by turning the VTC actuator counterclockwise. If not locked, turn the VTC actuator clockwise until it stops, then recheck it. If it is still not locked, replace the VTC actuator.
  1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with the pointer (B) on the engine block.

  1. Set the camshafts to TDC. The punch mark (A) on the variable valve timing control (VTC) actuator and the punch mark (B) on the exhaust camshaft sprocket should be at the top. Align the TDC marks (C) on the VTC actuator and exhaust camshaft sprocket.

  1. Install the cam chain on the crankshaft sprocket with the colored piece (A) aligned with the mark (B) on the crankshaft sprocket.

  1. K20Z2 engine: Install the cam chain on the VTC actuator and the exhaust camshaft sprocket with the punch marks (A) aligned with the two colored pieces (B).

  1. K24A3 engine: Install the cam chain on the VTC actuator and the exhaust camshaft sprocket with the punch marks (A) aligned with the center of the two colored pieces (B).

  1. Install the cam chain guide (A) and cam chain tensioner arm (B).

  1. Install the auto-tensioner.

  1. Install the cam chain guide B.

  1. Remove the pin or lock pin (P/N 14511-PNA-003) from the auto-tensioner.
  1. Check the chain case oil seal for damage. If the oil seal is damaged, replace the chain case oil seal.
  1. Remove all of the old liquid gasket from the chain case mating surfaces, bolts, and bolt holes.
  1. Clean and dry the chain case mating surfaces.

  1. Apply liquid gasket, P/N 08C70-K0234M, 08C70-K0334M, or 08C70-X0331S, evenly to the engine block mating surface of the chain case.
  1. Apply liquid gasket to the engine block upper surface contact areas (A) on the chain case and lower block upper surface contact areas (B) on the chain case.

  1. Apply liquid gasket, P/N 08C70-K0234M, 08C70-K0334M or 08C70-X0331S, evenly to the oil pan mating surface of the chain case.
    NOTE: Do not install components if 5 minutes or more have passed after applying the liquid gasket. Instead, remove the old residue and reapply the liquid gasket.

  1. Install the new O-ring (A) on the chain case. Set the edge of the chain case (B) to the edge of the oil pan (C), then install the chain case on the engine block (D). Wipe off the excess liquid gasket on the oil pan and chain case mating area.
    NOTE:
    • When installing the chain case, do not slide the bottom surface on the oil pan mounting surface.
    • Wait at least 30 minutes before filling the engine with oil.
    • Do not run the engine within 3 hours after installing the chain case.

  1. Install the side engine mount bracket.

  1. Install the upper bracket (A), then loosely tighten the bolt/nuts in the numbered sequence shown.
  1. Install the ground cable (B).

  1. Connect the crankshaft position (CKP) sensor connector (A) and VTC oil control solenoid valve connector (B).

  1. K24A3 engine: Install the oil cooler hose joint (A), using a new O-ring (B).
  1. Install the drive belt.
  1. Install the splash shield.
