Cylinder Head Chrysler Crossfire I final

To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of aluminum engine components and multi-layer steel cylinder head gaskets.

Note. Multi-Layer Steel (MLS) head gaskets require a scratch free sealing surface.

Remove all gasket material from cylinder head and block. See STANDARD PROCEDURE . Be careful not to gouge or scratch the aluminum head sealing surface.

Clean all engine oil passages.

Scheme 34

1. Before cleaning, check for leaks, damage and cracks.
2. Clean the cylinder head coolant and oil passages.
3. Check the cylinder head for flatness. CAUTION: 0.20 mm (0.008 in.) MAX is a combined total dimension of the stock removal limit from cylinder head and block top surface (Deck) together.
4. The cylinder head must be flat within: Standard dimension = less than 0.002 in. (0.05 mm) Service Limit = 0.008 in. (0.2 mm) Grinding Limit = Maximum of 0.008 in. (0.2 mm) is permitted.

Scheme 35

1. Position the cylinder head gasket and the cylinder head on the engine block dowels. NOTE: Measure and inspect cylinder head bolts before reuse. Do not reuse bolts that exceed 144 mm (1) in length. NOTE: Apply a thin coat of lubricant to head bolt threads before installing.
2. Install, but do not tighten the cylinder head bolts (1).
3. Use the tightening sequence chart to tighten the cylinder head bolts. NOTE: Bolts numbered 9 and 10 are timing chain cover bolts. They should be tightened after the cylinder head bolts are tightened.
4. Tighten the cylinder head bolts in four stages. Stage one, 10 N.m (7 ft. lbs.) Stage two, 30 N.m (22 ft. lbs.) Stage three, Rotate bolts 90° clockwise. Stage four Rotate bolts 90° clockwise. Tighten bolts 9 and 10 to 20 N.m (7-15 ft. lbs.).
5. Using Special Tools 9104 and 9105 Camshaft Locating Plates, lock the camshafts.
6. Install the camshaft sprockets and bolts (1).
7. Tighten the camshaft sprocket bolts in two stages. Stage one, 50 N.m (37 ft. lbs). Stage two, Rotate bolts 90° clockwise.
8. Remove the cable tie (1).
9. Install the timing chain tensioner (1). Tighten the timing chain tensioner to 80 N.m (60 ft. lbs.).
10. Remove Special Tools 9104 and 9105 Camshaft Locating Plates.
11. Check for a crankshaft position of 40° ATDC. See «OPERATION»(ref-306563-S29510291192008121700000) .
12. Connect the exhaust system at the manifold flanges and tighten the exhaust flange bolts to 20 N.m (15 ft. lbs.).
13. Install the cylinder head covers. See «INSTALLATION»(ref-306563-S10057957892008121700000) .
14. Install the intake manifold. See «INSTALLATION»(ref-306563-S16711987872008121700000) .
15. Install and connect the ignition coils. Refer to «INSTALLATION»(ref-306588-S32846808472008121700000) .
16. Install the accessory drive belt. Refer to «INSTALLATION»(ref-306586-S10147609092008121700000) .
17. Install and connect the radiator fan with the radiator. Refer to «INSTALLATION»(ref-306586-S11683754282008121700000) .
18. Install the camshaft position sensor and bolt (2). Connect the camshaft position sensor harness connector (1). Tighten the bolt to 10 N.m (7 ft. lbs.).
19. Install the engine air cleaner housing.
20. Fill the cooling system. Refer to «STANDARD PROCEDURE»(ref-306586-S31939057842008121700000) .
21. Fill the engine oil. See «STANDARD PROCEDURE»(ref-306563-S17946985482008121700000) .
22. Start the engine and check for leaks during warm up.
23. Recheck all fluid levels.
