IF COOLANT IS VISIBLE IN THE
SURGE TANK:
If coolant is visible in the tank but
the level is not up to the
FULL
COLD
mark, wait a while for the
engine to cool, then add a
50/50 mixture of clean water and
DEX-COOL
®
coolant at the
coolant surge tank. See "Engine
Coolant" in the "Service and
Maintenance" section.
IF NO COOLANT IS VISIBLE IN
THE SURGE TANK:
Add a 50/50 mixture of clean
water and DEX-COOL
®
coolant at
the coolant surge tank.
Here's how to add coolant to the
surge tank:
1. To remove the cap when the
cooling system is no longer
hot, turn it slowly one full turn
to the left and then stop.
If you hear a "hiss", wait for
that to stop. The "hiss" means
there is still some pressure left.
Then continue to slowly turn
the cap and remove it.
2. Fill the reservoir with the
proper mixture of coolant and
clean water up to the
FULL
COLD
mark.
3. With the pressure cap off, start
the engine and let it run until
you can feel that the upper
radiator hose is getting hot
(watch out for the engine
cooling fan).
