Engine Torque Specifications
TORQUE - 3.5L
CYLINDER HEAD BOLT TORQUE SEQUENCE
Tighten the cylinder head bolts in the following sequence, using the 4 step torque-turn method. Tighten according to the following torque values:
- Step 1: All to 61 Nm (45 ft. lbs.)
- Step 2: All to 88 Nm (65 ft. lbs.)
- Step 3: All (again) to 88 Nm (65 ft. lbs.)
- Step 4: + 90° Turn Do not use a torque wrench for this step.
INTAKE MANIFOLD BOLT TORQUE SEQUENCE
LOWER
Install intake manifold bolts and gradually tighten in sequence shown until a torque of 28 Nm (250 in. lbs.) is obtained.
UPPER
Tighten bolts to 12 Nm (105 in.lbs.) starting in the center working outward in a cross sequence pattern.
CRANKSHAFT MAIN BEARING BOLT TORQUE SEQUENCE
- Install each main cap and tighten bolts finger tight. The main bearing cap bolts must be tightened in the proper sequence. First the inner main cap bolts, secondly the windage tray bolts, lastly the main cap tie (horizontal) bolts.
- Install the inside main bearing cap bolts and tighten to 20 Nm + 1/4 turn (15 ft. lbs. + 1/4 turn).
- Install windage tray. Lubricate bolts with engine oil and tighten to 27 Nm + 1/4 turn (20 ft. lbs. + 1/4 turn).
- Install the main cap tie (horizontal) bolts and tighten to 28 Nm (250 in. lbs.).
EXHAUST MANIFOLD BOLT TORQUE SEQUENCE
Install the retaining bolts. Tighten 4 bolts starting at the center working outward to 23 N.m (200 in. lbs.).
