Caution
1.If the concentration of the coolant is below the anti-corrosion property, will adversely
affected. In addition, if the concentration is abov e
both the anti-freeze and cooling
properties will decrease, affecting the engine adve rsely. For these reasons, be sure to maintain
the concentration level within the specified range.
2. Do not use a mixture of different brands of anti -freeze.

causes enters the high pressure chamber in the lash
adjusters, the air in the high pressure chamber wil l be
pressurized during opening of the valve, which caus es
the lash adjusters to shrink excessively, and an abnormal

is the same phenomenon as the one when the valve
clearance has been excessively adjusted by mistake.
In this case, if the air which has entered the lash adjusters
is bled, things will be normalized.
