TORQUE SPECIFICATIONS










CYLINDER HEAD TORQUE AND SEQUENCE





NOTE: Measure and inspect cylinder head bolts before reuse. Do not reuse bolts that exceed 144 mm (1) in length.

NOTE: Apply a thin coat of lubricant to head bolt threads before installing.





1. Install, but do not tighten the cylinder head bolts (1).




2. Use the tightening sequence chart to tighten the cylinder head bolts.

NOTE: Bolts numbered 9 and 10 are timing chain cover bolts. They should be tightened after the cylinder head bolts are tightened.

3. Tighten the cylinder head bolts in four stages.
- Stage one, 10 Nm (7 ft. lbs.)
- Stage two, 30 Nm (22 ft. lbs.)
- Stage three, Rotate bolts 90° clockwise.
- Stage four Rotate bolts 90° clockwise.
- Tighten bolts 9 and 10 to 20 Nm (7-15 ft. lbs.).

INTAKE MANIFOLD TORQUE

Intake manifold bolts 20 Nm (15 ft. lbs.)

CAMSHAFT BEARING BRIDGE





1. Install, but do not tighten the bearing bridge bolts.
2. Tighten the M7 45 (short) bolts to 15 Nm (11 ft. lbs) and the M7 84 (long) bolts to 10 Nm (8 ft. lbs) in the sequence shown above.




3. Continue to tighten only the M7 84 (long) bolts in the sequence shown an additional 90° clockwise. Skipping M7 45 bolts (short bolts) this time.

MAIN BEARING CAP TORQUE AND SEQUENCE





1. Follow the torque sequence shown for the crankshaft main bearing journal cap bolts.
2. Main bearing journal caps must be tightened in two stages.
- Stage one for m8 bolts, 20 Nm (15 ft. lbs.).
- Stage two for m8 bolts, rotate 90° clockwise.
- Stage one for m10 bolts, 30 Nm (22 ft. lbs.).
- Stage two for m10 bolts, rotate 90° clockwise.

3. Turn the crankshaft to check for unobstructed movement.

ROD BEARING CAP TORQUE

Tighten the connecting rod bolts in three stages.
- Stage one, 5 Nm (44 in. lbs.)
- Stage two, 25 Nm (18 ft. lbs.)
- Stage three, rotate bolts 90° clockwise.

HARMONIC BALANCER TORQUE

1. Measure the vibration damper bolt. Replace the bolt if length exceeds 78 mm.
2. Position the vibration damper on the front of the crankshaft.
3. Lubricate the bolt threads with engine oil before installing.
4. Install the vibration damper bolt and tighten:
- 1st to 200 Nm (148 ft. lbs.),
- Then retighten the bolt an additional 90° clockwise.

FLYWHEEL TORQUE AND SEQUENCE

Initially tighten the flywheel bolts to 45 Nm (33 ft. lbs.). For final torque, rotate the flywheel bolts an additional 45° clockwise using a torque angle gauge.

FLYWHEEL TORQUE

NOTE: New flywheel/flexplate bolts must be used.





1. Install the spacer and new flywheel/flexplate bolts (1). Tighten bolts to 45 Nm (33 ft. lbs.)
2. Rotate the flywheel/flexplate bolts an additional 90° clockwise.

OIL PUMP TORQUE





Oil pump 20 Nm (15 ft. lbs.)

EXHAUST MANIFOLD TORQUE

Exhaust manifold 35 Nm (26 ft. lbs.)

WATER PUMP TORQUE

Water pump 35 Nm (26 ft. lbs.)
