3.
caution |
Do not pressures 100 kPa or
more.
|
Install the radiator tester and pressures at 100
kPa. 4.Hold the pressurized state for 20 minutes,
and check that the engine coolant leakage
from the drain hole, the vapour hole or the installation
surface of the water pump. 5.Remove the radiator
tester, and install the radiator cap. 6.Warm up
the engine, let it idle for 20 minutes and stop
it. 7.After stopping the engine, and check that
the engine coolant leakage from the drain
hole, the vapour hole or the installation surface of the
water pump. 8.If the engine coolant leakage is
found in step 4 or 7, replace the water pump (Refer
to ).
