Handling notes for coolant
Coolant is potentially harmful and should be
handled with special care.
WARNING
If coolant splashes in your eyes, thor-
oughly wash them with water and consult
a doctor.
If coolant splashes on your clothes,
quickly wash it away with water and then
with soap and water.
If coolant is swallowed, induce vomiting
and get immediate medical attention.
CAUTION:
Adding water instead of coolant lowers
the antifreeze content of the coolant. If
water is used instead of coolant, check,
and if necessary, correct the antifreeze
concentration of the coolant.
Use only distilled water. However, soft
water may be used if distilled water is not
available.
