To Check Coolant
When your engine is cold, the coolant level should be
at
"FULL COLD" or a little higher. When your engine is
warm, the level should be up to "FULL HOT" or a little
higher.
To Add Coolant
If you need more coolant, add the proper mix at the
coolant recovery 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 (1 05 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.
