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 to the left until it first 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.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.

To Add Coolant
If you need more coolant, add the proper mix at the
cnolclnt recoverv tank.
Add coolant mix at the recovery tank, but be careful not
to spill it.
Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, an AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches
a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.
