Even when the water pump is normal,
a residue of the engine coolant draining may be found on the
drain hole, the vapour hole and the installation surface of
the water pump. If a residue of the engine coolant draining
is found, check the water pump leakage by following
method.
|
|
1.Wipe off the residue of
the engine coolant draining on the water pump.

3.
caution |
Do not pressures 100 kPa or
more.
|
Install the radiator tester and pressures at 100
kPa. 4.Hold the pressurised 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
