Engine Torque Specifications
TORQUE
CYLINDER HEAD TORQUE AND 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.
Necking can be checked by holding a straight edge against the threads (2). If all the threads do not contact the scale, the bolt should be replaced.
NOTE: The four smaller cylinder head mounting bolts require sealant to be added to them before installing. Failure to do so may cause leaks. The locations are identified with an *.
1. Lubricate the cylinder head bolt threads with clean engine oil and install the eight M11 bolts.
2. Coat the four M8 cylinder head bolts with Mopar(R) Lock and Seal Adhesive then install the bolts.
NOTE: The cylinder head bolts are tightened using an angle torque procedure, however, the bolts are not a torque-to-yield design.
3. 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 SEQUENCE
Intake manifold retaining bolts in sequence shown 12 Nm (105 in. lbs.)
CAMSHAFT BEARING CAP TORQUE AND SEQUENCE
1. Working in 1/2 turn increments, tighten the bearing cap retaining bolts starting with the middle cap working outward.
2. 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°.
HARMONIC BALANCER TORQUE
Vibration damper bolt 175 Nm (130 ft. lbs.)
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.
FLYWHEEL TORQUE
Flywheel Torque 95 Nm (70 Ft. Lbs)
OIL PUMP AND TIMING CHAIN TENSIONER TORQUE AND SEQUENCE
1. Position the oil pump onto the crankshaft and install one oil pump retaining bolt.
2. Position the primary timing chain tensioner and install three retaining bolts.
3. Tighten the oil pump and primary timing chain tensioner retaining bolts to 28 Nm (250 in. lbs.) in the sequence shown.
EXHAUST MANIFOLD TORQUE AND SEQUENCE
Install remaining conical washers. Starting at the center arm and working outward, tighten the bolts and nuts to 25 Nm (18 ft. lbs.).
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.
