ENGINE COOLING SYSTEM (Cont’d)
Replacing The Coolant
Do not remove radiator cap when the engine is
hot. You can be seriously burned.
W–2070–1285
Open the rear door. Open the rear grill.
Remove the radiator cap (Item 1) [A].
Remove the drain plug (Item 1) [B] from the side of the
engine block. Drain the coolant into a container.
After all the coolant is removed, install and tighten the
drain plug.
Mix the coolant in a separate container See
SPECIFICATIONS, Page 9–1 for correct capacity.
Fill the radiator and engine block with the premixed
coolant.
Install the radiator cap.
Fill the coolant recovery tank 1/3 full.
Run the engine until it is at operating temperature. Stop
the engine. Check the coolant level in the recovery tank
when cool. Add coolant to the recovery tank as needed.
Propylene Glycol
Add premixed coolant; 47% water and 53% propylene
glycol to the recovery tank if the coolant level is low.
One gallon and one pint of propylene glycol mixed with
one gallon of water is the correct mixture of coolant to
provide a –34°F (–37°C) freeze protection.
I–2124–0497
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.
