Checking Radiator CapINFOID:0000000001534602
 Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.
 Pull negative-pressure valve to open it, and make sure that it is
completely closed when released.
- Make sure that there is no dirt or damage on the valve seat of radi-
ator cap negative-pressure valve.
- Make sure that the valve operates properly in the opening and
closing conditions.
 Check radiator cap relief pressure using suitable tool.
- When connecting the radiator cap to the tester, apply water or
coolant to the cap seal surface.
- Replace the radiator cap if there is an abnormality in the negative-
pressure valve, or if the open-valve pressure is outside of the stan-
dard values.
 Replace radiator cap if there it does not comply to specifications to the above three checks.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorINFOID:0000000001534603
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 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/cm
2, 71 psi) and keep distance more than 30 cm
(11.8 in).

INSPECTION AFTER REMOVAL
WARNING:
Use a protector to prevent a burn during the work.
Thermostat
 Place a thread (A) so that it is caught in the valves of thermostat
(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
 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.
 After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.
 If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION
 Check that the reservoir tank cap is tightened.
 Check for leaks of engine coolant using suitable tools. Refer to CO-11, "
Inspection".
 Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.

NOTE:
When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-
functioning.
