When deciding the ratio of antifreeze to water, check the lowest temperature in the past, and decide from the mix-
ing table given below.
It is actually better to estimate and temperature about 10°C lower when deciding the mixing ratio.
The mixing ratio depends on the ambient temperature, but it should always be a minimum of 30% by volume (anti-
freeze/total amount of coolant x 100).
The freezing temperature of undiluted antifreeze is -15°C. Do not store undiluted antifreeze at a temperature of
below -15°C.
Mixing rate of water and antifreeze
WARNING
Antifreeze is flammable, so keep it away from flame.
Antifreeze is toxic. When removing the drain plug, be careful not to get water containing antifreeze on
you. If it gets in your eyes, flush your eyes with large amount of fresh water and see a doctor at once.
Use antifreeze and appropriate water for diluting. (for details, see “COOLANT AND WATER FOR DILUTION (4-
6)“)
We recommend use of an antifreeze density gauge to control the mixing proportions.
Prepare a container whose capacity is larger than the specified coolant volume to catch drained coolant.
Prepare a hose to supply antifreeze coolant and water.
1.
Turn cap (3) of the radiator water filler slowly.
2.
Set a container to catch the coolant under drain valve (4) at
the bottom of the radiator.
3.
Open drain valve (4) and drain the water.
4.
After draining the antifreeze solution, close drain valve (4),
then fill with clean water. After the radiator is filled with
water, start and run the engine at low idle speed. After the
water temperature rises above 90°C, run the engine for
about 10 minutes.
5.
Stop the engine and open drain valve (4) to drain the water.
6.
After draining the water, clean the radiator with detergent.
When carrying out the flushing operation, follow the
instructions given with the flushing agent.
7.
Close drain valve (4).
8.
Add coolant mixed with antifreeze until it overflows from the water filler.
Decide the proportions of antifreeze and water according to the table for the mixing rate of water and anti-
freeze.
