Engine Torque Specifications

TORQUE






CONNECTING ROD BOLT REUSE

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.

CYLINDER HEAD BOLT REUSE





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.

Necking can be checked by holding a straight edge against the threads. If all the threads do not contact the scale (1), the bolt should be replaced.

CYLINDER HEAD





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 through 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





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

CAMSHAFT BEARING CAPS





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

CRANKSHAFT MAIN BEARING CAPS





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 (5 ft. lbs.)
- Turn bolts 1 - 8 an additional 90°.
- Tighten bolts A - E 27 Nm ( 20 ft. lbs.).

OIL PUMP





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

EXHAUST MANIFOLD

Starting at the center arm and working outward, tighten the bolts and nuts to 25 Nm (18 ft. lbs.)

WATER PUMP





Tighten water pump mounting bolts to 54 Nm (40 ft. lbs.) torque.
