Engine coolant
1. Features of engine coolant
Properties of engine coolant for liquid-cooled engines are low freezing
points, high boiling points and reduces wear & tear. Its freezing point
temperature is -40°c and boiling point temperature is 108°c , prevents
the engine from over-heating while idling or revving at low speeds. It
also prevent the formation of harmful elements during the heat
dissipation process.
1. The factory-formulated viscosity of engine coolant is at 55% and is
able to use immediately without any other additional mixtures. Avoid
adding water when the coolant is at low level.
2. Do not use or mix with other brands of engine coolant.
3. The engine coolant has toxic properties & is strictly never to be
consumed.
2. Adding or topping-up of engine coolant
Place motorcycle at an angled level, ensuring the front wheel is
elevated 150mm or higher than the rear wheel. Open the radiator
cover and fill the radiator with the specified engine coolant.
Start the engine and fill the radiator subsequently with the engine
coolant, ensuring the level of the coolant is higher than the heat sink.
Allow the engine to idle and increase the engine rotation speed,
repeat the process 2-3 times till the radiator fan is activated. Pour &
fill up the radiator reservoir to the brim, after which tighten the top cap.
Fill the reserve water tank, which is located under the fuel tank, with
coolant. The amount of coolant should be filled up to the level between
the level letter indicators of “L”and “H”, above letter “L” and
below letter “H”.
Once completed, tighten the reserve tank cap securely.
3. Changing/Replacement of engine coolant
Place motorcycle level ground, deploy the side stand & let the engine
cool down to room temperature. Place servicing tray below the outlet
pipe under the engine, unscrew the cap and allow the coolant to drain
completely out of the engine. Next, secure the cap back tightly & begin
adding in new engine coolant.
4. Things to take note:
Avoid opening the radiator cap while its still hot & have yet to cool down.
The high and hot pressure within the radiator itself will be released with
immense pressure, forcing the hot engine coolant out together & may
cause scalding or even serious burns to the skin or eyes.
If there is a need to loosen the cylinder nut during repairs of the engine,
drain out all engine coolant first to prevent the coolant from entering the
crankcase.
Engine coolant maintenance
1. Check for water leakage for every 3000km travelled, inspect the area
between the water pump and connecting pipes. Make sure the
connecting pipes do not have damages or wear, inspect them by
pressing onto the pipes to ensure that there is no traces of major cracks.
If damages or wear are detected, send the motorcycle to authorised
repair centres for replacements and avoid self replacement or repairs.
2. Check engine coolant level for every 3000km travelled, inspect the level
of engine coolant at the radiator due to minor evaporation of coolant
during vehicle operation. Please ensure that the proper & correct coolant
is used top-ups and avoid adding water into the coolant reservoir.
Change or replace the old coolant with new if coolant turns cloudy or
it is due for replacement or change during interval servicing.
