Precautions for Engine Cooling System

WARNING
!
• You can be injured by boiling fluid or steam if you open the radiator cap when the engine is hot.
After the engine cools, wrap a thick cloth around cap and carefully remove the cap by turning it a
quarter turn to allow pressure to escape and then turn the cap all the way off.
• The engine must be cool before servicing the cooling system.
• Coolant is harmful:
– If it comes in contact with skin or eyes, flush with water.
– If swallowed accidentally, induce vomiting and call physician immediately.
– Keep it away from children.

Precautions for Engine Coolant

Refer to "Engine Coolant Recommendation in Section 0A (Page 0A-4)".
Engine Coolant Description
CAUTION
!
• Use a high quality ethylene glycol base
anti-freeze, mixed with distilled water. Do
not mix an alcohol base anti-freeze and
different brands of anti-freeze.
• Do not put in more than 60% anti-freeze or
less than 50%. (Refer to Fig. 1 and 2.)
At the time of manufacture, the cooling system is filled
with a 50:50 mixture of distilled water and ethylene
glycol anti-freeze. This 50:50 mixture will provide the
optimum corrosion protection and excellent heat
protection, and will protect the cooling system from
freezing at temperatures above –31 °C (–24 °F).
If the vehicle is to be exposed to temperatures below –
31 °C (–24 °F), this mixing ratio should be increased up
to 55% or 60% according to the figure.
