The complete procedure to replace Crossfire car model cylinder head.

Chrysler cylinder head removal/ install details are as follows:---

1. Drain the cooling system.
2. Drain the engine oil
3. Properly relieve the fuel system pressure.
4. Remove or disconnect the following:
   
   
   Negative battery cable

   Air intake assembly

   Mass Air Flow (MAF) sensor

   Radiator and radiator fan

   Camshaft position sensor

   Intake manifold

   Cylinder head cover

   Exhaust pipes from exhaust manifold
5. Rotate the crankshaft so that the crankshaft timing mark aligns with the 40 degree After Top Dead Center (ATDC) mark on the front cover as shown. Grooves in the camshafts must be toward the inside of the wedge.

To install:

Fig. Examine the head bolts for signs of stretching

1. Check the cylinder head bolts for signs of stretching. If length exceeds 5.67 inches (144 mm), replace bolts as necessary.
2. Lubricate the threads of the bolts with clean engine oil.
3. Install the cylinder heads. Use new gaskets and tighten the bolts, in sequence, as follows:
   1. Step 1: 7 ft. lbs. (10 Nm)
   2. Step 2: 22 ft. lbs. (30 Nm)
   3. Step 3: rotate bolts 90 degrees clockwise
   4. Step 4: rotate bolts 90 degrees clockwise
   5. Step 5: Bolts 9 and 10 to 7-15 ft. lbs. (10-20 Nm)

6. Lock the camshafts in place with Camshaft Locking Plates 9104 and 9105.
7. Install the camshaft sprockets. Tighten the bolts to 37 ft. lbs. (50 Nm), plus an additional 90 degrees.
8. Remove cable tie from timing chain.
9. Install the timing chain tensioner. Tighten the bolt to 59 ft. lbs. (80 Nm).
10. Remove camshaft locking plates
11. Ensure crankshaft is set to 40 degrees ATDC
12. Install or connect the following:
    
    
    Exhaust pipes to manifold. Tighten the bolts to 15 ft. lbs. (20 Nm).

    Cylinder head covers. Tighten the bolts to 89 inch lbs. (10 Nm).

    Intake manifold.

    Ignition coils

    Accessory drive belt

    Camshaft position sensor

    Radiator and radiator fan

    Mass Air Flow (MAF) sensor

    Air intake assembly

    Negative battery cable
13. Fill and bleed the cooling system.
14. Fill the engine with oil.
15. Start the engine and check for leaks.

These details will help.
