Normally-Open Four-Terminal Type
Check for continuity between the terminals:
- There should be continuity between terminals No. 1 and No. 2 when 12
volt battery power is
connected to terminal No. 3, and 12 volt battery ground is connected to
terminal No. 4.
- There should be no continuity between terminals No. 1 and No. 2 when 12
volt battery power is
disconnected.

Five-Terminal Type
Check for continuity between the terminals:
- There should be continuity between terminals No. 1 and No. 2 when 12
volt battery power is
connected to terminal No. 3, and 12 volt battery ground is connected to
terminal No. 5.
- There should be continuity between terminals No. 1 and No. 4 when 12
volt battery power is
disconnected.

RADIATOR CAP TEST
Test
1. Radiator Cap - Test
.png)
- Wait until the engine is cool, then carefully remove the radiator cap
(A). Wet the
radiator cap seal with engine coolant, then install it on a commercially
available
pressure tester (B)
- Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2, 13.5-17.8 psi)
- Check for a drop in pressure
- If the pressure drops, replace the radiator cap.

- Wait until the engine is cool, then carefully remove the radiator cap,
and fill
the radiator with engine coolant to the base of the filler neck
- Attach a commercially available pressure tester (A) to the radiator, and
apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm
2, 13.5-17.8 psi)
- Inspect for engine coolant leaks and a drop in pressure
- Remove the pressure tester, then reinstall the radiator cap.
RADIATOR AND A/C CONDENSER FAN MOTOR TEST
Test
1. Fan Motor - Test
.png)
- Disconnect the connectors from the radiator fan motor (A) and the
A/C condenser fan motor (B).
- Test each motor by connecting 12 volt battery power to terminal No.
1 and ground to terminal No. 2.
- If a motor fails to run or does not run smoothly, replace it.
