NOTE: IT IS IMPERATIVE THAT THE COOLING SYS-
TEM AIR BLEED SCREW BE OPENED BEFORE ANY
COOLANT IS ADDED TO THE COOLING SYSTEM.
FAILURE TO OPEN THE BLEED SCREW FIRST
WILL RESULT IN AN INCOMPLETE FILL OF THE
SYSTEM.
(5) Open the cooling system bleed screw (Fig. 6).
(6) Pour a 50/50 mix of Mopart Antifreeze/Coolant,
5 Year/100,000 Mile Formula and distilled water into
the coolant pressure bottle (Fig. 7).
(7) Slowly fill the cooling system until a steady
stream of coolant flows from the hose attached to the
bleed screw (Fig. 6).
(8) Close the bleed screw and continue filling sys-
tem to the top of the COLD FILL RANGE (Fig. 8).
(9) Remove hose from bleed screw.
(10) Install cap on coolant pressure bottle.
(11) Start engine and run until it reaches operat-
ing temperature.
(12) If removed, install front belly pan (Refer to 23
- BODY/EXTERIOR/BELLY PAN - INSTALLATION).
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 cool-
ant level in the pressure bottle may occur.
CLEANING
Drain, flush, and fill the cooling system at the
mileage or time intervals specified (Refer to LUBRI-
CATION & MAINTENANCE/MAINTENANCE
SCHEDULES - DESCRIPTION). If the solution is
dirty, rusty or contains a considerable amount of sed-
iment, clean and flush with clean water. Care should
be taken in disposing of the used engine coolant from
your vehicle. Check governmental regulations for dis-
posal of used engine coolant.
