lnstall in the reverse order of removal. Make note of
these items;
. lf you're instslling a new condenser, add refriger-
ant oil (ND-olL 8: P/N 38897-PR7-A01AH or 38899- PR7 - A01) (see page 22-211.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-1344) to avoid leakage.
a Do not damage the radiator and condenser fins
when installing the condenser.
o Be sure to install the condenser mount cushions
securely into the holes.
. Charge the system {see page 22-39) and test its
performance (see page 22-241.

Fan Motor Test
Disconnect the 2P connector from the fan motor.
Test the motor by connecting battery power to the
B terminal, and ground to the A termlnal.
lf the fan motor fails to run smoothly, replace it.
NOTE: The illustration shows the radiator fan.
Radiator Fan Switch Test
NOTE: Bleed air from the cooling system after installing
the radiator fan switch (see section 10)
1. Remove the radiator fan switch from the thermostat
housing.
2. Suspend the radiator fan switch in a container ol
coolanl as shown.
Heat the coolant and check engine coolant tempera
ture with a thermometer.
Check the continuity between the A and B terminals
according to the table:

Engine Coolant Temperature (ECT) Gauge
Gauge Test
NOTE: Refer to page 23-123 for the wiring description of
the engine coolant temperature (ECT) gauge circuit dia-
gram.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire trom the ECT gauge send-
ing unit and ground it with a jumper wire.
YEL/GRN WIRESENDING UNIT
Turn the ignition switch ON (ll).
Check that the pointer of the ECT gauge starts mov-
ing toward the "H" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "H" on the gauge dial. Failure to do
so may damage the gauge.
a lf the pointer of the gauge does not move at all,
check lor an open in the YEL or YEL/GRN wire.
lf the wires are OK, replace the ECT gauge.
a lf the ECT gauge works, test the ECT sending
unrt.
ECT Sending Unit Test
Disconnect the YEL/GRN wire from the ECT send-
ing unit.
With the engine cold, use an ohmmeter to measure
resistance between the positive terminal and the en-
gine (ground).
Check the temperature ol the coolant.
Run the engine and measure the change in resistance
with the engine at operating temperature (the radi-
ator fan comes on).
5. It the obtained readings are substantially different
from the sDecifications above, replace the ECT send-
Ing unrt.
