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, the bolt should be replaced
CAUTION: When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use only a wooden or plastic scraper.
- Clean the cylinder head and cylinder block mating surfaces
- Position the new cylinder head gasket on the locating dowels.
CAUTION: When installing cylinder head, use care not damage the tensioner arm or the guide arm.
- Position the cylinder head onto the cylinder block. Make sure the cylinder head seats fully over the locating dowels.
NOTE: The four smaller cylinder head mounting bolts require sealant to be added to them before installing. Failure to do so may cause leaks.
- Lubricate the cylinder head bolt threads with clean engine oil and install the ten M10 bolts.
- Coat the four M8 cylinder head bolts with Mopar Lock and Seal Adhesivethen 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.
- Tighten the bolts in sequence using the following steps and torque values:
- Step 1: Tighten bolts 1–10, 27 N·m (20 ft. lbs.).
- Step 2: Verify that bolts 1–10, all reached 27 N·m (20 ft. lbs.), by repeating step-1 without loosening the bolts. Tighten bolts 11 thru 14 to 14 N·m (10 ft. lbs.).
- Step 3: Tighten bolts 1–10, 90 degrees.
- Step 4: Tighten bolts 1–10, 90 degrees, again. Tighten bolts 11–14, 26 N·m (19 ft. lbs.)
- Install the secondary chain and secondary chain guide
- Install the cylinder head access plug.
- Re-set and install the right side secondary chain tensioner
- Remove Special Tool 8515.
- Install the timing chain cover
- Install the crankshaft damper
- Install accessory drive belt
- Install the cylinder head cover (Install the intake manifold
- Install oil fill housing onto cylinder head.
- Refill the cooling system
- Raise the vehicle.
- Install the exhaust pipe onto the right exhaust manifold.
- Lower the vehicle.
- Reconnect battery negitive cable.
- Start the engine and check for leaks.
