2GR-FE COOLING – COOLING FAN SYSTEMCO–5
CO
ON-VEHICLE INSPECTION
1. INSPECT COOLING FAN SYSTEM
(a) Put the vehicle in the following conditions:
(1) The engine switch is off.
(2) The coolant temperature is less than 95
C
(203
F).
(3) The battery voltage is between 9 and 14 V.
(4) The A/C switch is OFF.
(b) Clamp the 400 A probe of an ammeter over the M+
wire of each cooling fan motor.
(c) Turn the ignition switch to the ON position and wait
for approximately 10 seconds. Check that the fan
stops.
(d) Start the engine. Check that the fan stops with the
engine idling.
HINT:
• Make sure that the radiator engine coolant
temperature is less than 95
C (203F).
• Turn the A/C switch OFF.
(e) Check that the fan operates when the A/C switch is
turned ON (MAX COOL and the magnetic clutch is
operating).
Standard current
HINT:
The coolant temperature is less than 95
C (203F).
(f) Check that the fan operates when the engine
coolant temperature sensor connector is
disconnected.
Standard current
Item Specified Condition
No. 1 cooling fan motor 5 to 14 A
No. 2 cooling fan motor 4 to 12 A

INSTALLATION
1. INSTALL TORQUE CONVERTER CLUTCH
ASSEMBLY
(a) Install the torque converter clutch to the automatic
transaxle.
(b) Using vernier calipers and a straight edge, measure
the dimension "A" between the transaxle fitting part
of the engine and the converter fitting part of the
drive plate (*1).
(c) Using vernier calipers and a straight edge, measure
the dimension "B" shown in the illustration and
check that "B" is greater than "A" (measured in step
(*1)).
Standard:
A + 1 mm (0.03937 in.) or more
NOTICE:
Remember to minus the thickness of the
straight edge.
2. INSTALL AUTOMATIC TRANSAXLE ASSEMBLY
(a) Install the automatic transaxle to the engine with the
10 bolts.
Torque: Bolt A
64 N*m (650 kgf*cm, 47 ft.*lbf)
Bolt B
46 N*m (470 kgf*cm, 34 ft.*lbf)
Bolt C
43 N*m (439 kgf*cm, 32 ft.*lbf)
(b) Apply a few drops of adhesive to each of 2 threads
on the tip of the 6 torque converter clutch mounting
bolts.
Adhesive:
Part No. 08833-00070, THREE BOND 1324
or equivalent
(c) Install the 6 torque converter clutch mounting bolts.
Torque: 41 N*m (413 kgf*cm, 30 ft.*lbf)
NOTICE:
First install the black colored bolt, and then the
remaining 5 bolts.
