COOLING SYSTEM BLEEDING
GASOLINE ENGINES
Air in system will collect under radiator cap. As engine
reaches operating temperature, coolant and any trapped air will enter
reserve tank. As engine cools, a vacuum will be created which will
draw only coolant into cooling system. After engine has gone through a
warm-up and cooling cycle, run engine until it again reaches operating
temperature. Ensure coolant in reserve tank is at warm coolant mark on
reserve tank or dipstick.
5.9L DIESEL ENGINE
For bleeding procedures on 5.9L diesel, see appropriate 12-
valve or 24-valve engine article in ENGINES. DO NOT operate engine
while filling cooling system.

SPECIAL ENGINE MARKS
Information identifying undersize and oversize components is
found at various engine locations and is decoded as follows:
Crankshaft & Rod Journals
The letter "M" (main) or "R" (rod) followed by number
indicates which main or rod bearing journal is .001" (.02 mm)
undersize. The mark is stamped on No. 6 crankshaft counterweight on 3.
9L, No. 8 crankshaft counterweight on 5.2L and No. 3 crankshaft
counterweight on 5.9L engines.
Cylinder Block - Letter "A" following engine serial number
indicates .020" (.51 mm) oversize cylinder bores:
* A diamond-shaped stamp, located on top pad at front of engine
and stamped on flat area of each oversize lifter bore,
indicates .008" (.20 mm) oversize lifters.
* A stamp "X" indicates .005" (.13 mm) oversize valve stems.
The stamp is found on machined pad, near two 3/8" tapped
holes on each end of cylinder head.
ADJUSTMENTS
VALVE CLEARANCE ADJUSTMENT
Hydraulic valve lifters are used. No valve adjustment is
required.

TROUBLE SHOOTING
NOTE: To trouble shoot mechanical engine components, see
appropriate table in TROUBLE SHOOTING article in GENERAL
INFORMATION.
REMOVAL & INSTALLATION
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
NOTE: For installation reference, label all electrical connectors,
vacuum hoses and fuel lines before removal. Also place mating
marks on engine hood and other major assemblies before
removal.
FUEL PRESSURE RELEASE
CAUTION: Fuel system is under pressure. Pressure must be released
before servicing fuel system components.
Gasoline
1) Disconnect negative battery cable. Loosen fuel tank cap to
release tank pressure. Press on filler tube flap to relieve any
additional tank pressure.
NOTE: Fuel filler tube has spring-loaded flap located below fuel
fill cap to serve as secondary seal if fuel fill cap is not
tightened. It is part of EVAP monitor system when vehicle is
equipped with leak detection pump (LDP). Vehicle may be
equipped with flap installed into fuel filler tube even if
vehicle is NOT equipped with LDP and EVAP monitor system.
2) Remove fuel pump relay from Power Distribution Center
(PDC). For location of relay, refer to label on underside of PDC
cover. Start and run engine until it stalls. Attempt restarting engine
until it will no longer run.
3) Unplug connector from an injector. Attach one end of a
jumper wire (18 gauge or smaller) with alligator clips to either
injector terminal. Connect other end of jumper wire to positive side
of battery. Connect one end of a second jumper wire to remaining
injector terminal.
WARNING: Powering an injector for more than a few seconds will
permanently damage injector.
4) Touch other end of second jumper wire to negative terminal
of battery for no more than a few seconds. Place a rag below fuel
line. Disconnect quick-connect fitting at fuel rail. See FUEL LINE
DISCONNECT FITTINGS. Return fuel pump relay to PDC.
Compressed Natural Gas Fuel Tube Purging (5.2L)
1) Close control valve (clockwise) on all fuel cylinders.
Open manual shutoff valve (open when handle is parallel to fuel
tubes).
2) Start and operate engine until it runs out of fuel.
Attempt 3 more engine starts. If check valve or fuel fill receptacle
