How to Add Coolant to the
Radiator
When the coolant in the coolant
recovery tank is at the FULL mark,
start the vehicle.
If the overheat warning continues,
there is one more thing that can
be done. Add the proper coolant
mixture directly to the radiator but
be sure the cooling system is
cool before you do it.
{
CAUTION
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.
Wait for the cooling system and
CAUTION (Continued)
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
Turning the radiator pressure cap
when the engine and radiator are
hot can allow steam and scalding
liquids to blow out and burn you
badly. With the coolant recovery
tank, you will almost never have
to add coolant at the radiator.
Never turn the radiator pressure
cap — even a little — when the
engine and radiator are hot.
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 until it first

stops. Do not press down while
turning the pressure cap.
{
CAUTION
If you hear a hiss, wait for that to
stop. A hiss means there is
still some pressure left.
2. Keep turning the pressure cap,
but now push down while turning.
Remove the pressure cap.
3. Fill the radiator with the proper
coolant mixture, up to the base
of the filler neck. For more
information about the proper
coolant mixture look earlier in
this section.
4. Then fill the coolant recovery
tank to the FULL mark.
