How to Add Coolant to the
Radiator
{
WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{
WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the surge tank pressure
cap — even a little — they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot.
(Continued)
WARNING (Continued)
Wait for the cooling system and
surge tank pressure cap to cool if
you ever have to turn the
pressure cap.
If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done.
1. Remove the pressure cap when
the cooling system, including
the pressure cap and upper
radiator hose is no longer hot.
Turn the pressure cap
slowly counterclockwise.
If a hiss is heard, wait for that to
stop. A hiss means that there is
still some pressure left.
2. Keep turning the pressure cap
and remove it.
3. Fill the cooling system with the
proper DEX-COOL coolant
mixture, up to the base of the
filler neck. See “What to use” for
more information about the
proper coolant mixture. Rinse or
wipe any spilled coolant from the
engine and the compartment.
4. Then fill the coolant recovery
tank to the COLD FILL line.
