7. COOLANT & BLEEDING CHECK
CAUTION
■ It is best to use proper coolant LLC as normal water will help increase chances of internal rust from
the radiator and engine related parts.
■ DO NOT open the radiator cap when the engine is running or while it is still hot as the water from
the radiator may spray boiling hot water onto you.
（1） Check that the radiator hose clamp is securely fastened.
（2） Have the heater control set to MAX.
(The air plug is a copper washer bolt near the warning label.)
（3） Release the air from radiator cap via the bolt.
（4） At approx less than 2L/min fill the coolant tank to with coolant to bleed any air from inside.
Once coolant bleed from bleeding plug, tighten it and fill to the required level before closing the cap.
（5） Have a new copper washer ready for when closing the air plug.

（6） Close the radiator cap and keep the engine at idle until the thermostat circulates the coolant.
（7） Check the water temp gauge to see if the temperature is rising and also carefully feel the lower hose if
there is warm water flowing through it.

there is warm water flowing through it.
（8） Once the thermostat is checked and working properly, checks the water temperature to see that it is
not rising abnormally fast. You can do this by holding the revs at 2,500 RPM for 10secs at a time for
about 2-3 times.
（9） Stop the engine.
（10） After the engine has cooled down, open the radiator cap and check the coolant fluid level again to see
if the coolant level has dropped or not. If it has then you will need to repeat the above process again.
（11） When the fluid is no longer receding then you can top it up to the noted limit or till you reach the max
on the reservoir.
（12） Start the engine, let the engine idle at 3000rpm, and check that the heater core has the sound of water
flowing through it at the instrument panel lower section. If you hear the sound then you will need to
repeat the above process until the liquid level stop dropping.
