(a) Remove the pressure port union.
(b) Remove the O–ring from the union.
4. REMOVE FLOW CONTROL VALVE AND SPRING
5. REMOVE REAR HOUSING, WAVE WASHER AND SIDE
REAR PLATE
(a) Using 2 screwdrivers, remove the snap ring.
(b) To prevent oil seal lip damage, wind vinyl tape on the ser-
rated part of the vane pump shaft.
(c) Using a plastic hammer, tap out the rear housing, wave
washer and side rear plate.
(d) Remove the O–ring from the rear housing.
(e) Remove the O–ring from the side rear plate.
6. REMOVE CAM RING AND 10 VANE PLATES
NOTICE:
Be careful not to drop the plate.
7. REMOVE VANE PUMP SHAFT WITH VANE PUMP RO-
TOR AND SIDE FRONT PLATE
8. REMOVE VANE PUMP ROTOR AND SIDE FRONT
PLATE
(a) Using a screwdriver, remove the snap ring from the vane
pump shaft.
(b) Remove the vane pump rotor and side front plate.
(c) Remove the 2 O–rings from the side front plate.
9. REMOVE SHORTER STRAIGHT PIN

4. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON and check that the receiver
gauge needle indicates COOL.
(c) Ground terminal on the wire harness side connector
through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge.
Then recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
5. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, test the bulb.

6. INSPECT LOW OIL PRESSURE SWITCH CONTINUITY
(a) Disconnect the connector from the switch.
(b) Check that continuity exists between terminal and ground
with the engine stopped.
(c) Check that no continuity exists between terminal and
ground with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the switch.
