ROUTINE LEVEL CHECK
Do not remove pressure bottle cap f o r r o u t i n e
coolant level inspections.
The coolant deaeration pressure bottle provides a
quick visual method for determining the coolant level
w i t h o u t removing the pressure cap. W i t h the engine
cold the level of the coolant i n the coolant pressure
bottle should be above the top seam of bottle. *
ADDING ADDITIONAL COOLANT
The r a d i a t o r c a p s h o u l d . not be r e m o v e d .
When additional coolant is needed to m a i n t a i n this
level, i t is necessary to fill the coolant recovery bottle
through the overflow hose. Remove the hose from the
pressure bottle neck, to fill the coolant recovery bot-
tle (Fig. 12). No access is provided to the coolant bot-
tle cap. Use only 50/50 concentration of ethylene
glycol type antifreeze and water.

- When servicing the cooling system, i t is essential
t h a t coolant does not drip onto the accessory drive
belt and/or pulleys. Shield the belt w i t h shop towels
before w o r k i n g on the cooling system. I f coolant con-
tacts the belt or pulley, flush both w i t h clean water.
(1) Remove radiator d r a i n p l u g located, at- the
lower left side of radiator (Fig. 13).
(2) Remove coolant pressure bottle cap.
(3) Remove the cylinder block drain plug(s) located
behind each exhaust manifold.

Use Mopar® Coolant, or an equivalent as necessary
for best engine cooling w i t h o u t corrosion. Refer to
Coolant Performance i n this group for appropriate
coolant mixture.
(1) Install radiator drain plug.
(2) Install the cylinder block drain plugs.
(3) Slowly f i l l coolant pressure bottle.
(4) I t may be necessary to bleed air from the cool-
ing system. This can be done by using the following
procedures: -
a. Ensure the heater control valve is i n the open
position.
* b. Remove cooling system bleed plug from thermo-
stat housing (Fig. 14).
c. Continue f i l l i n g cooling system u n t i l coolant is
level w i t h bleed p l u g opening.
• d. I n s t a l l cooling system bleed plug.
e. Continue f i l l i n g cooling system u n t i l coolant
level is above t h e ; t o p seam of'the coolant pressure
bottle.
(5) Install cap on coolant pressure bottle.
