Engine Torque Specifications

TORQUE






Cylinder Head Torque and 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 the bolts should be replaced.






Tighten the bolts in sequence using the following steps and torque values:
- Step 1: Tighten bolts 1-8, 27 Nm (20 ft. lbs.).
- Step 2: Verify that bolts 1-8, all reached 27 Nm (20 ft. lbs.), by repeating step 1 without loosening the bolts. Tighten bolts 9 thru 12 to 14 Nm (10 ft. lbs.).
- Step 3: Tighten bolts 1-8, 90 degrees.
- Step 4: Tighten bolts 1-8, 90 degrees, again. Tighten bolts 9-12, 26 Nm (19 ft. lbs.)

Intake Manifold Torque and Tightening Sequence






Install the intake manifold retaining bolts and tighten in sequence shown to 12 Nm (105 in. lbs.).

Camshaft Bearing Cap and Torque Sequence






1. Install the camshaft bearing caps, hand tighten the retaining bolts.

NOTE: Caps should be installed so that the stamped numbers on the caps are in numerical order, (1 through 4) from the front to the rear of the engine. All caps should be installed so that the stamped arrows on the caps point toward the front of the engine.

2. Working in 1/2 turn increments, tighten the bearing cap retaining bolts starting with the middle cap working outward.
3. Tighten the camshaft bearing cap retaining bolts to 11 Nm (100 in. lbs.).

Main bearing Cap Torque and Sequence






Install the bedplate retaining bolts, making sure to place the stud bolts in the correct location, Torque the bolts in the sequence shown.
- Hand tighten bolts 1D,1G and 1F until the bedplate contacts the block.
- Tighten bolts 1A - 1J to 54 Nm (40 ft. lbs.)
- Tighten bolts 1 - 8 to 7 Nm (62 in. lbs.)
- Turn bolts 1 - 8 an additional 90°.
- Tighten bolts A - E 27 Nm ( 20 ft. lbs.).

Rod Bearing Cap Torque

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

Lubricate NEW rod bolts and bearing surfaces with engine oil. Install connecting rod cap and bearing. Tighten the NEW 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 95 Nm (70 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.
