Radiator Water Leakage
1. Pour a specified amount of water into the radiator.
2. Set a radiator tester (1) and an adaptor (2) and raise the water
pressure to the specified pressure (210 kPa, 2.14 kgf/cm
30.5 psi).
3. Check the radiator for water leaks.
4. For water leak from the pinhole, repair with the radiator cement.
When water leak is excessive, replace the radiator.

NOTE
• The pressure of the leak test is different from each radiator
specification.
Thus, do the leak test, refer to the test pressure of each
radiator specification.
(1) Radiator Tester
Resistance of Throttle Body
1. Disconnect the connector.
2. Measure the resistance between terminal 1 and terminal 4 with
an ohmmeter.
3. If the resistance is 0 ohm or infinity, replace it.
4. Measure the resistance between terminal 2 and terminal 3 with
an ohmmeter.
5. If the resistance is not with in the factory specifications, replace
it.
