2003 CHEVROLET TRACKER radiator cap

CAUTION: (Continued)
Never turn the cap when the cooling system,
including the radiator pressure cap, is hot.
Wait for the cooling system and radiator
pressure cap to cool if you ever have to turn
the pressure cap.
How to Add Coolant to the Radiator
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise until
it ®rst stops. (Don't press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
5-37

2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.3. Fill the radiator with the proper coolant mixture, up
to the base of the ®ller neck. See
Engine Coolant
on page 5-28for more information about the proper
coolant mixture.
4. Then ®ll the coolant recovery tank to the FULL mark.
5. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.
5-38

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
7. By this time, the coolant level inside the radiator
®ller neck may be lower. If the level is lower, add
more of the proper coolant mixture through the
®ller neck until the level reaches the base of the
®ller neck.8. Then replace the pressure cap. At any time during
this procedure if coolant begins to ¯ow out of the
®ller neck, reinstall the pressure cap. Be sure
the arrows on the pressure cap line up like this.
