ON-VEHICLE SERVICE
ENGINE COOLING
14-10
11.Turn the A/C switch to OFF position to start the
engine and warm up until the cooling fan
operates.
NOTE: This work is to open the thermostat fully.
12.Rev the engine several times and then stop it.
Check that there are no coolant leaks.
13.Remove the radiator cap with the engine cool,
and then refill the engine coolant up to the top of
the radiator port.
14.Tighten the radiator cap securely.
CAUTION
Do not overfill the radiator condenser tank.
15.Remove the radiator condenser tank cap, and
add the engine coolant up to the "FULL" line.
16.Install the front under cover panel (Refer to
GROUP 51
− Under Cover − Removal and
Installation ).
CONCENTRATION MEASUREMENT
M1141001101582
CAUTION
• Engine coolant of less than 30% concentra-
tion has a less rust-proof effect. In a concen-
tration of over 60%, the antifreeze effect and
engine cooling performance of the engine
coolant are deteriorated, causing a detrimen-
tal effect on the engine. Therefore, observe
the service concentration range without fail.
• Use the Dia Queen Super Long Life Coolant
Premium without adding water because the
concentration is preadjusted to 50%.
Using a hydrometer, check if the engine coolant con-
centration is within the standard value range.
Standard value: 30 to 60% (service concen-
tration range)
WATER PUMP COOLANT LEAK CHECK
M1141008600842
Even when the water pump is normal, a residue of
the 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 coolant draining is
found, check the water pump leakage by following
method.
1. Wipe off the residue of the coolant draining on the
water pump.
WARNING
Make sure that the coolant is cold when
removing the radiator cap.
2. Remove the radiator cap.
CAUTION
Do not pressurise 100 kPa or more.
3. Install the radiator cap tester, and pressurise with
100 kPa.
4. Hold the pressurised state for 20 minutes, and
check that the water leakage from the drain hole,
the vapour hole or the installation surface of the
water pump.
5. Remove the radiator cap tester, and install the
radiator cap.
6. Warm up the engine, let it idle for 20 minutes and
stop it.
7. After the engine is stopped, check the water
leakage from the drain hole, the vapour hole or
the installation surface of the water pump.
8. If the water leakage is confirmed in the items 4
and 7, replace the water pump. (Refer to
)
