Radiator 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.
You
can be burned if
you
spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a
hot engine.
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.
