(b) Submerge the switch in fuel, and check that the bulb goes
out.
If operation is not as specified, replace the sender gauge.
7. INSPECT RECEIVER ENGINE COOLANT
TEMPERATURE 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 connecter
through a 3.4 W test bulb.
(d) Turn the ignition switch ON, 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, re-
check the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
8. INSPECT ENGINE COOLANT TEMPERATURE
RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
w/ Tachometer:
Between terminalsResistance (W)
D - EApprox. 51.0
D - FApprox. 148.6
E - FApprox. 199.6
w/o Tachometer:
Between terminalsResistance (W)
A - BApprox. 54.0
A - CApprox. 175.7
B - CApprox. 229.7
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order. This circuit includes the
diode.

REMOVAL
1. REMOVE COOLING UNIT
(See page AC-27)
2. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all the coolant.
3. DISCONNECT WATER HOSES FROM HEATER RA-
DIATOR PIPES
HINT:

Push the water hose onto the heater radiator pipe as far
as the ridge on the pipe.

Install the hose clip in a position, as shown in the illustra-
tion.
4. REMOVE PIPE GROMMETS
5. REMOVE INSTRUMENT PANEL SAFETY PAD AND
REINFORCEMENT (See page BO-48)
