INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using a radiator cap tester adapter (special service tool: EG17650301)
and a radiator cap tester (commercial service tool). Refer to CO-9, "
LEAK CHECK" .
Start and warm up engine. Visually check if there is no leaks of engine coolant and A/T fluid (A/T models).
Checking Radiator CapEBS00KOK
1. Pull negative-pressure valve to open it and make sure that it
closes completely when released.
Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.
2. Check radiator cap relief pressure.
When connecting radiator cap to radiator cap tester (commer-
cial service tool) and radiator cap tester adapter (special ser-
vice tool), apply engine coolant to radiator cap seal surface.
Replace radiator cap if there is an unusualness in negative-
pressure valve, or if the relief pressure falls below the limit.
Checking RadiatorEBS00KOL
Check radiator for mud or clogging. If necessary, clean radiator as follows.
Be careful not to bend or damage radiator fins.
When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downward.
Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm2 , 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.

INSPECTION AFTER REMOVAL
Place a string so that it is caught in the valves of thermostat and
water control valve. Immerse fully in a container filled with water.
Heat while stirring. (The example in the figure shows thermo-
stat.)
The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
Continue heating. Check the full open valve lift amount.
NOTE:
The full open valve lift amount standard temperature for water
control valve is the reference value.
After checking the full open valve lift amount, lower the water
temperature and check the valve closing temperature.
Standard:
If out of the standard, replace either or both thermostat and water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
Thermostat and Water Control Valve
Install thermostat with making rubber ring groove fit to thermo-
stat flange with the whole circumference. (The example in the
figure shows thermostat.)
NOTE:
Same procedure is applied for installation of water control valve.
Install thermostat with jiggle valve facing upwards. (The position
deviation may be within the range of 20 degrees as shown in the
figure.)
Install water control valve with the arrow facing up and the frame
center part facing upwards. (The position deviation may be
within the range of 20 degrees as shown in the figure.)
Heater Pipe Installation
Apply a neutral detergent to O-ring, then quickly insert the insertion part of heater pipe into cylinder block.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using a radiator cap tester adapter (special service tool: EG17650301)
and a radiator cap tester (commercial service tool). Refer to CO-9, "
LEAK CHECK" .
Start and warm up engine. Visually check if there is no leaks of engine coolant and A/T fluid (A/T models).
