Hi, glad to be of help. Here is the procedure:
STANDARD PROCEDURE - COOLING SYSTEM
WARNING: MAKE SURE ENGINE COOLING SYSTEM
IS COOL BEFORE REMOVING PRESSURE CAP OR
ANY HOSE. SEVERE PERSONAL INJURY MAY
RESULT FROM ESCAPING HOT COOLANT. THE
COOLING SYSTEM IS PRESSURIZED WHEN HOT.
CAUTION: Do not use well water, or suspect water
supply in cooling system. Use only a 50/50 mixture
of the specified ethylene glycol type antifreeze/coolant
and distilled water. (Refer to LUBRICATION &
MAINTENANCE/FLUID TYPES - DESCRIPTION).
(1) Close radiator draincock by turning the stem
clockwise to the 3:00 o’clock position. Hand tighten
(2) Install engine block drain plugs, if removed.
WARNING: WHEN INSTALLING DRAIN HOSE TO AIR
BLEED VALVE, ROUTE HOSE AWAY FROM ACCESSORY
DRIVE BELTS, ACCESSORY DRIVE PULLEYS,
AND ELECTRIC COOLING FAN MOTORS.
(3) Attach one end of a 6.35 mm (0.250 in.) ID
clear hose that is approximately 1200 mm (48 in.)
long, to the bleed valve.
² Bleed Valve Location (2.7L): Located on the
water outlet connector at the front of engine (Fig. 5).
² Bleed Valve Location (3.5L): Located on the
lower intake manifold, left of center and below the
upper intake plenum (Fig. 5).
(4) Route hose away from the accessory drive belt,
drive pulleys and electric cooling fan. Place the other
end of hose into a clean container. The hose will prevent
coolant from contacting the accessory drive belt
when bleeding the system during the refilling operation
(5) Open the cooling system bleed valve (Fig. 5).
(6) Attach Special Tool 8195, Filling Aid Funnel to
pressure bottle filler neck (Fig. 6).
(7) Use the supplied clip to pinch overflow hose
that connects between the two chambers of the coolant
bottle (Fig. 6).
CAUTION: Do not mix coolants. If coolant is used
other than specified, a reduction in corrosion protection
(8) Pour a 50/50 mix of Mopart Antifreeze/Coolant,
5 Year/100,000 Mile Formula and distilled water into
the larger section of Filling Aid Funnel (the smaller
section of funnel is to allow air to escape). For system
capacity, (Refer to LUBRICATION & MAINTENANCE
- SPECIFICATIONS - FLUID CAPACITIES).
(9) Slowly fill the cooling system until a steady
stream of coolant flows from the hose attached to the
bleed valve (Fig. 5).
(10) Close the bleed valve and continue filling system
to the top of the Filling Funnel.
(11) Remove clip from overflow hose (Fig. 6).
(12) Allow the coolant in Filling Funnel to drain
into overflow chamber of the pressure bottle.
(13) Remove Special Tool 8195, Filling Aid Funnel.
Install cap on coolant pressure bottle.
(14) Remove hose from bleed valve.
(15) Start engine and run until it reaches operating
NOTE: The engine cooling system will push any
remaining air into the coolant bottle within about an
hour of normal driving. As a result, a drop in coolant
level in the pressure bottle may occur. If the
engine cooling system overheats and pushes coolant
into the overflow side of the coolant bottle, this
coolant will be sucked back into the cooling system
ONLY IF THE PRESSURE CAP IS LEFT ON THE
BOTTLE. Removing the pressure cap breaks the
vacuum path between the two bottle sections and
the coolant will not return to cooling system.
(16) Shut off engine allow it to cool down. This
permits coolant to be drawn into the pressure chamber.
(17) With engine COLD, observe coolant level in
pressure chamber. Coolant level should be within
MIN and MAX marks. Adjust coolant level as necessary.
NOTE: The coolant bottle has two chambers. Coolant
will normally only be in the inboard (smaller) of
the two. The outboard chamber is only to recover
coolant in the event of an overheat or after a recent
service fill. The outboard chamber should normally
be empty. If there is coolant in the overflow side of
the coolant bottle (after several warm/cold cycles of
the engine) and coolant level is within MIN and MAX
marks, disconnect the end of the overflow hose at
the fill neck and lower it into a clean container.
Allow coolant to drain into the container until emptied.
Reconnect overflow hose to fill neck.
