Engine Torque Specifications

TORQUE






Cylinder Head Tightening Sequence






NOTE: The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down (2) the bolts should be replaced.






6. Tighten the bolts in sequence using the following steps and torque values:
- Step 1: Tighten bolts 1-10, 20 Nm (15 ft. lbs.).
- Step 2: Tighten bolts 1-10, 47 Nm (35 ft. lbs.). Tighten bolts 11-14, 25 Nm (18 ft. lbs.).
- Step 3: Tighten bolts 1-10, 90 degrees. Tighten bolts 11-14, 30 Nm (22 ft. lbs.).

Intake Manifold Tightening Sequence

Install the ignition coils (1,2) and manifold retaining bolts and torque from the center bolts, moving front to back in a crisscross pattern to 12Nm (106 in. lbs.).

Camshaft Bearing Cap and Torque Sequence






1. Install the camshaft bearing caps, hand tighten the retaining bolts.
2. Working in 1/2 turn increments, tighten the bearing cap retaining bolts following the torque sequence.
3. Tighten the camshaft bearing cap retaining bolts to 11 Nm (100 in. lbs.).

Main bearing Cap Torque and Sequence






NOTE: Lubricate the bedplate retaining bolts with clean engine oil prior to installation.

Install the bedplate retaining bolts, making sure to place the stud bolts in the correct location, Torque the bolts in the sequence shown.
- Tighten bolts A - L to 54 Nm (40 ft. lbs.)
- Tighten bolts 1-10 to 2.8 Nm (25 in. lbs.)
- Turn bolts 1-10 an additional 90°.
- Tighten bolts A1- A6 to 27 Nm (20 ft. lbs.)

Rod Bearing Cap Torque

CAUTION: Connecting Rod Bolts are Torque to Yield Bolts and Must Not Be Reused. Always replace the Rod Bolts whenever they are loosened or removed.

Lubricate rod bolts and bearing surfaces with engine oil. Install connecting rod cap and bearing. Tighten bolts to 27 Nm (20 ft. lbs.) plus 90°.

Flex Plate Torque and Sequence






1. Position the flexplate onto the crankshaft and install the bolts hand tight.
2. Tighten the flexplate retaining bolts to 60 Nm (45 ft. lbs.) in the sequence shown.

Oil Pump Torque and Sequence





Tighten the oil pump and primary timing chain tensioner retaining bolts to 28 Nm (250 in. lbs.) in the sequence shown.

Water Pump Torque and Sequence






Using a new gasket, position water pump (1) and install mounting bolts as shown. Tighten water pump mounting bolts to 58 Nm (43 ft. lbs.) torque.
