Checking and Replenish Coolant
1. Without recovery tank (2) :
Remove the radiator cap (1) and check to see that the coolant
level is just below the port.
With recovery tank (2) :
Check to see that the coolant level lies between FULL "A" and
LOW "B".
2. If coolant level is too low, check the reason for decreasing
coolant.
(Case 1)
If coolant is decreasing by evaporation, replenish only fresh,
soft water.
(Case 2)
If coolant is decreasing by leak, replenish coolant of the same
manufacture and type in the specified mixture ratio (fresh, soft water
and L.L.C.). If the coolant brand cannot be identified, drain out all of
the remaining coolant and refill with a totally new brand of coolant
mix.
CAUTION
• Do not remove the radiator cap until coolant temperature is
below its boiling point. Then loosen the cap slightly to
relieve any excess pressure before removing the cap
completely.
IMPORTANT
• During filling the coolant, air must be vented from the
engine coolant passages. The air vents by jiggling the
radiator upper and lower hoses.
• Be sure to close the radiator cap securely. If the cap is
loose or improperly closed, coolant may leak out and the
engine could overheat.
• Do not use an antifreeze and scale inhibitor at the same
time.
• Never mix the different type or brand of L.L.C..
