MDX & 3.2CL

  1. Ensure cylinder head temperature is less than 100°F (38°C). On 3.2CL, remove strut brace. On all models, remove ignition coil cover and intake manifold cover. On 3.2CL Type S models, remove water bypass hoses. Disconnect Traction Control System (TCS) control valve actuator and TCS control valve angle sensor connector from TCS control valve assembly. Remove bolt securing TCS control valve bracket. On all models, remove Evaporative Emission (EVAP) control canister hose, breather tube, vacuum hose and intake air duct. Loosen lock nuts and remove throttle and cruise control cables.
  2. Remove brake booster vacuum hose, vacuum hoses, and PCV hose. Remove breather pipe and water bypass hose. Remove power steering hose clamp. Disconnect intake manifold runner control (IMRC) actuator connector. Remove IMRC actuator. Remove 2 bolts from wire harness holder. Remove Intake Air Temperature (IAT), Idle Air Control (IAC), Throttle Position Sensor (TPS) and Manifold Absolute Pressure (MAP) sensor connectors. On MDX, also disconnect EVAP canister purge valve connector. On all models, remove wire harness clamps and holders. Move wire harness out of way. Remove upper intake cover and intake manifold. Remove cylinder head covers.
  3. Rotate crankshaft clockwise until cylinder No. 1 is at TDC. Cylinder No. 1 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Loosen valve adjusting screw lock nuts and adjust valve clearances on cylinder No. 1. See VALVE CLEARANCE ADJUSTMENT (MDX, 3.2CL & 3.2TL)  table. Tighten valve adjusting screw lock nut to 14 ft. lbs. (20 N.m) and recheck valve clearance.
  4. Rotate crankshaft clockwise until cylinder No. 4 is at TDC. Cylinder No. 4 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Adjust valves on cylinder No. 4.
  5. Rotate crankshaft clockwise until cylinder No. 2 is at TDC. Cylinder No. 2 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Adjust valves on cylinder No. 2.
  6. Rotate crankshaft clockwise until cylinder No. 5 is at TDC. Cylinder No. 5 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Adjust valves on cylinder No. 5.
  7. Rotate crankshaft clockwise until cylinder No. 3 is at TDC. Cylinder No. 3 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Adjust valves on cylinder No. 3.
  8. Rotate crankshaft clockwise until cylinder No. 6 is at TDC. Cylinder No. 6 TDC mark on camshaft sprocket should be aligned with TDC pointer on timing belt cover. Adjust valves on cylinder No. 6. After adjusting valves, reinstall removed components and ensure crankshaft pulley bolt is tightened to 181 ft. lbs. (245 N.m).
