Fuel Injection I
Engine coolant temperature (ECT) sensor,
testing
The ECT sensor is located on the front of the engine in the
coolant~thermostat flange. The ECT sensor is a dual temper-
ature sensor. One circuit provides coolant temperature infor-
mation to the ECM while the other circuit provides coolant
temperature information to the instrument cluster.
The ECM determines the correct ignition timing and
airlfuel
mixture required for the engine by monitoring an applied volt-
age
(5 vdc) to the sensor. Thevoltage drop across the sensor
varies as the coolant temperature (sensor resistance) chang-
es.
NOTE-
The ECT sensor is an NTC (negative temperature coeffi-
cient) type sensor. In other words, as the temperature rises,
resistance through the sensor decreases.
If the ETC sensor input is faulty or non-plausible, the MIL is il-
luminated when OBD
II fault criteria are exceeded. The ECM
assumes a substitute value
(80" C/ 176°F) to maintain engine
operation. The ignition timing is set to a
conse~ativelsafe ba-
sic setting.
Disconnect harness from
ECTsensor (A) at coolant flange at
front of engine.
- Check ECT sensor resistance using a multimeter at sensor
terminals
3 and 4. Peel back protective boot (B) to ID termi-
nal numbers on connector housing.

- Before refilling radiator:
Switch ignition to
ON. (Do not start engine).
Set temperature controls to full warm.
Set blower control to low.
- Using a coolant mixture of 50% antifreeze and 50% distilled
water, fill expansion tank slowly. Continue until coolant
emerges from bleed screw. Cooling system capacity is listed
in Table c. Cooling system capacity (6-cylinder models).
NOTE-
Be sure radiator bleed screw is loose when filling cooling
system.
Tap water may cause corrosion of radiator, engine and
coolant hoses.
Coolant can be reusedprovided it is clean and less than
two years old. Do not reuse coolant when replacing dam-
aged engine parts.

4 V-8 engine: Remove transmission mounting Tom-head bolts
(arrows). Note length and location of bolts.
Remove transmission by pulling backward until transmis-
sion input shaft clears clutch disc splines, then pull down-
wards. Lower transmission jack to remove transmission.
- Installation is reverse of removal, keeping in mind the
following:
When installing a new transmission, be sure to transfer
parts from old transmission
if applicable.
Thoroughly clean input shafl and clutch disc splines. Light-
ly lubricate transmission input shaft before installing.
* Be sure bellhousing alignment dowel sleeves are located
correctly. Replace damaged sleeves.
Center rear of transmission in driveshaft tunnel before
tightening transmission support bracket.
NOTE-
In order to avoid difficulties in transmission removal at a fu-
ture time, use washers with Torx-head mounting bolts.
- Reinstall driveshaft. Use new nuts when mounting driveshaff
to transmission/flex disc. See 260 Driveshaft.
- Refill transmission with appropriate lubricant before starting
or towing car. See Transmission fluid service earlier in this
repair group.
