INSTALLATION
| CAUTION | Do not use harsh cleaners to clean the cylinder head covers. Severe damage to covers may occur. |
| CAUTION | Do not allow other components including the wire harness to rest on or against the engine cylinder head cover. Prolonged contact with other objects may wear a hole in the cylinder head cover. |
Note. The cylinder head cover gasket may be used again, provided no cuts, tears, or deformation have occurred.
Scheme 62
- Clean the cylinder head cover (1) and the sealing surface of the cylinder head (2). Inspect and replace gasket if necessary.
- Install the cylinder head cover and hand start all fasteners. Using the sequence shown in illustration, tighten the cylinder head cover bolts to 8 N.m (70 lbs in.).
- Before installing the ignition coils, apply dielectric grease to the inside of the spark plug boots (1).
- Install the ignition coils. NOTE: Right side shown in illustration, left side similar.
- Tighten the ignition coil retaining bolts (3) to 7 N.m (62 in. lbs.).
- Position the electrical harness (2).
- Connect the ignition coil electrical connectors (1).
- Install the engine cover (2).
- Connect the negative battery cable (1).
Scheme 63
Scheme 64
- Disconnect the negative battery cable (1).
- Remove the engine cover.
- Remove the ignition coils (1). Refer to «COIL, IGNITION, REMOVAL»(ref-476549-S10820283682012060400000) .
- Using the sequence shown in illustration, remove the cylinder head cover. Refer to «COVER(S), CYLINDER HEAD, REMOVAL, 5.7L»(ref-476518-S01379202482012060400000) .
- Install the pushrod retainer (special tool #9070, Retainer, Push Rod) (1).
- Using the sequence shown in illustration, loosen the rocker shafts retaining bolts. CAUTION: The rocker shaft assemblies are not interchangeable between the intake and the exhaust, failure to install them in the correct location could result in engine damage. The intake rocker arms (1) are marked with the letter "I" (2). CAUTION: Do not remove the retainers (1) from the rocker shaft (3).
- Remove the rocker shaft (3). Note the rocker shaft location during removal. CAUTION: The longer pushrods are for the exhaust side and the shorter pushrods are for the intake side.
- Remove the pushrods. Note the pushrod location during removal.
| CAUTION | The longer pushrods are for the exhaust side and the shorter pushrods are for the intake side. |
- Install the pushrods in the same order as removed.
- Install the pushrod retainer (special tool #9070, Retainer, Push Rod) (1). CAUTION: Make sure that the retainers (1) and the rocker arms (2) are not overlapped when tightening bolts or engine damage could result. CAUTION: Due to the changes in the pushrod clearance holes in the Eagle 5.7L cylinder heads, close attention must be given when installing the pushrod(s) into the tappet(s). Once the pushrod(s) have been installed, use a suitable light to look down through the pushrod hole(s). This will allow you to verify the pushrod(s) are centered properly in the tappet(s) and avoid engine damage. Recheck after the rocker shaft assembly has been installed and tightened to specification. CAUTION: The rocker shaft assemblies are not interchangeable between the intake and the exhaust, failure to install them in the correct location could result in engine damage. The intake rocker arms (1) are marked with the letter "I" (2).
- Install the rocker shaft assemblies in the same order as removed.
- Using the sequence shown in illustration, tighten the rocker shaft bolts to 22 N.m (16 ft. lbs.). CAUTION: Do Not rotate or crank the engine during or immediately after rocker arm installation. Allow the hydraulic roller tappets adequate time to bleed down (about five minutes).
- Remove pushrod retainer (special tool #9070, Retainer, Push Rod) (1).
- Using the sequence shown in illustration, install the cylinder head cover. Refer to «COVER(S), CYLINDER HEAD, INSTALLATION, 5.7L»(ref-476518-S24184402652012060400000) .
- Install the ignition coils (1). Refer to «COIL, IGNITION, REMOVAL»(ref-476549-S10820283682012060400000) .
- Install the engine cover.
