Checking Coolant Level
To avoid personal injury or death:
A
Do not remove radiator cap while coolant is
hot. When cool, slowly rotate cap to the first
stop and allow sufficient time for excess
pressure to escape before removing the cap
completely.
1. Check to see that the coolant level is between the
"FULL" and "LOW" marks of recovery tank.
2. When the coolant level drops due to evaporation, add
soft water only up to the full level.
In case of leakage, add anti-freeze and soft water in
the specified mixing ratio up to the full level.
(See "Flushing Cooling System and Changing
Coolant" in "EVERY 2 YEARS" in "PERIODIC
SERVICE" section.)
3. When the coolant level is lower than "LOW" mark of
recovery tank, remove the radiator cap and check to
see that the coolant level is just below the port. If level
is low, add coolant.

If the radiator cap has to be removed, follow the
caution above and securely retighten the cap.
