ENGINE COOLING SYSTEM (Cont’d)
Replacing The Coolant
A
Remove the rear grill. (See REAR GRILL Page 36.)
1
Open the rear door.
Remove the radiator cap (Item 1) [A].
P–10744
Connect a hose to the coolant drain valve (Item 1) [B]
(located behind the engine oil filter) or use a funnel to keep
B
coolant from getting into the engine compartment.
Open the valve and drain all the coolant into a container.
Close the valve.
1
Fill the radiator with premixed coolant and install the
radiator cap. (See Checking the Coolant Level Page 42
for premix recommendations.)
Fill the coolant recovery tank 1/3 full with premixed
coolant (Item 1) [C]. P–13023
Check the radiator cap for correct pressure rating or
overheating can result.
C
Check for leaks in the cooling system. Check for worn or
damaged hoses, clamps or radiator. Check for loose or
worn water pump belt.
Replace damaged parts immediately to prevent leaks and
overheating.
Install the radiator cap and the rear grill and close the rear
door. 1
P–10760
AVOID ENGINE DAMAGE
Always use the correct ratio of water to anti-
freeze.
Too much antifreeze reduces cooling system
efficiency and may cause serious premature
engine damage.
Too little antifreeze reduces the additives
which protect the internal engine compo-
nents; reduces the boiling point and freeze
protection of the system.
Always add a premixed solution. Adding full
strength concentrated coolant can cause seri-
ous premature engine damage.
