V6 Valve Clearance
- Disconnect negative battery cable. Disconnect ignition system connector. Use a 5 mm Allen wrench to remove control pressure regulator. Lay pressure regulator on intake manifold.
- Disconnect hoses and remove oil filler cap. Remove vacuum pump. Remove air inlet duct. Remove A/C compressor bracket bolts and set compressor aside. DO NOT disconnect refrigerant hoses. Remove valve covers.
- Rotate crankshaft so that No. 1 cylinder is at TDC of compression (firing) stroke. Adjust intake valves of cylinder No. 1, No. 2 and No. 4. Adjust exhaust valves of cylinder No. 1, No. 3 and No. 6.
- Rotate crankshaft 360 degrees (one turn). This will set No. 1 cylinder at TDC of exhaust stroke. Adjust intake valves of cylinder No. 3, No. 5 and No. 6. Adjust exhaust valves of cylinder No. 2, No. 4 and No. 5. Install valve covers.
NOTE:
Crankshaft pulley has 2 notches. When No. 1 cylinder is at TDC, upper notch will align with "0" notch on timing marker. Second notch is TDC for No. 6 cylinder when aligned with "0" on timing marker. See Figure
