MANIFOLD - EXHAUST
DESCRIPTION
The exhaust manifolds are log style with a patented flow enhancing design to maximize performance. The exhaust
manifolds are made of high silicon molybdenum cast iron. A perforated coregraphite exhaust manifold gasket is
used to improve sealing to the cylinder head. The exhaust manifolds are covered by a three layer laminated heat
shield for thermal protection and noise reduction. The heat shields are fastened with a torque prevailing nut that is
backed off slightly to allow for the thermal expansion of the exhaust manifold.

COVER - TIMING
REMOVAL
1. Disconnect the battery negative cable.
2. Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).

CAUTION:The4.7LengineusesanRTVsealer
instead of a gasket to seal the front cover to the
engine block, from the factory. For service, Mopar

INSTALLATION
CAUTION: Do not use oil based liquids to clean
timing cover or block surfaces. Use only rubbing
alcohol, along with plastic or wooden scrapers.
Use no wire brushes or abrasive wheels or metal
scrapers, or damage to surfaces could result.
1. Clean timing chain cover and block surface using
rubbing alcohol.
CAUTION: The 4.7L can use a special RTV sealer
instead of a carrier gasket to seal the timing cover
to the engine block, from the factory. For service
repairs, Mopar
Grey Engine RTV must be used as
a substitute, if RTV is present. If the front cover
being used has no provisions for the water pas-
sage o-rings, then Mopar
Grey Engine RTV must
be applied around the water passages.
2. Inspect the water passage o-rings, if equipped for
any damage, and replace as necessary.
3. Apply Mopar
Grey Engine RTV sealer to the front
cover following the path above, using a 3 to 4mm
thick bead.

sequence as shown in to 58 Nꞏm (43 ft. lbs.).
5. Install the A/C compressor and generator.
6. Install crankshaft damper (Refer to 9 - ENGINE/
ENGINE BLOCK/VIBRATION DAMPER - INSTAL-
LATION).
7. Install accessory drive belt tensioner assembly.
Tighten fastener to 54 Nꞏm (40 ft. lbs.).
8. Install lower radiator hose.
9. Install both heater hoses.
10. Fill cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).

CAUTION: Care should be taken not to damage
camshaft target wheel. Do not hold target wheel
while loosening or tightening camshaft sprocket.
Do not place the target wheel near a magnetic
source of any kind. A damaged or magnetized tar-
get wheel could cause a vehicle no start condition.
CAUTION: Do not forcefully rotate the camshafts
or crankshaft independently of each other. Damag-
ing intake valve to piston contact will occur.
Ensure negative battery cable is disconnected to
guard against accidental starter engagement.
13. Remove left and right camshaft sprocket bolts.

adjustable pliers (1), remove the left camshaft
sprocket. Slowly rotate the camshaft approxi-
mately 15 degrees clockwise to a neutral position.
15. While holding the right camshaft steel tube with
adjustable pliers (1), remove the right camshaft
sprocket. Slowly rotate the camshaft approxi-
mately 45 degrees counterclockwise to a neutral
position.
16. Remove idler sprocket assembly bolt.
17. Slide the idler sprocket assembly and crank
sprocket forward simultaneously to remove the
primary and secondary chains.
