MEASURES AGAINST COLD OR HOT WEATHER
3-12
Measures to be taken when the engine has
overheated
CAUTION
If the engine has overheated, do not open the radiator cap.
In addition, do not touch the radiator reservoir tank. Hot
steam might spout out, causing burns.
When the engine has overheated:
1) Let the engine run at idle rpm for a while and open the engine
hood fully to get a good ventilation.
2) After making sure the temperature of the cooling water cools
down sufficiently, shut down the engine.
3) Open the reservoir tank and add cooling water.
4) Check for water leaks of the cooling system, clogged radiator
fin, and loose fan belt.
IN HOT WEATHER
Cooling system
CAUTION
Make sure the engine is cold before opening or closing the
radiator cap. Hot cooling water might spout out to cause
serious burns.
To get a good cooling effect, use caution not to allow leakage of
cooling water and the forming of scale or corrosion in the cooling
system.
• In hot weather, the cooling system is apt to cause scale or
corrosion. Use caution to get the circulation of clean water at
all times. The LLC can be used for all seasons, because it has
anti-rust and anti-corrosion effect in addition to anti-freezing
effect.
• A clogged radiator fin will cause an overheated engine. Keep
the radiator fins always clean. In addition, check for water leaks.
• Check for a loose fan belt. If the fan belt is loose, adjust it for
the specified tension.
