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 (2) 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, the bolt should be replaced.

1. Lubricate the cylinder head bolt threads with clean engine oil and install the ten 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 1-10, 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 TORQUE AND 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 12 Nm (106 in. lbs.).

CAMSHAFT BEARING CAP TORQUE AND SEQUENCE





NOTE: Position the left side camshaft so that the camshaft sprocket dowel is near the 1 o'clock position, This will place the camshaft at the neutral position easing the installation of the camshaft bearing caps.

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 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°.

HARMONIC BALANCER TORQUE

CAUTION: Special Tool 8512-A, is assembled in a specific sequence. Failure to assemble this tool in this sequence can result in tool failure and severe damage to either the tool or the crankshaft.

1. Assemble Special Tool 8512-A as follows, The nut (2) is threaded onto the shaft first. Then the roller bearing (1) is placed onto the threaded rod (3) (The hardened bearing surface of the bearing (1) MUST face the nut (2). Then the hardened washer (5) slides onto the threaded rod. Once assembled coat the threaded rod's threads with MOPAR (R) Nickel Anti-Seize or equivalent.




2. Using Special Tool 8512-A, press damper onto crankshaft (1).
3. Install then tighten vibration damper bolt to 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 60 Nm (45 ft. lbs.) in the sequence shown.

FLYWHEEL TORQUE

Flywheel Torque 95 Nm (70 Ft. Lbs)

OIL PUMP 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

Tighten all manifold bolts starting at center and working outward 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.
