Location of temperature sensor that operates the temperature gauge


Follow the upper rad hose to the thermostat housing. It will be there. There are two, one is the ECT (engine coolant temperature SENSOR) and the other is the temperature SENDING UNIT (input for temp. gauge ONLY). f83e91b9-4b48-476a-8c50-10735b376bf1.png

Location of engine coolant temperature sensor


Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

NOTE
The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.

Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

NOTE
Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

Where is the temp gage sensor location 2001 merk cougar


Hi there,

The temperature gauge relies on readings from the Engine Coolant Temp (ECT) Sensor.

The ECT sensor is usually located on (or near) the thermostat/coolant housing.

Refer to component No. 8 (2.0L Engine):

Refer to component No. 9 (2.5L Engine) locate under bypass tube:

Hope this helps.

Where is the coolent control sensor located on a 2002 LT trailblazer


2.2L & 2.4L Engines
  1. Turn OFF the ignition.
  2. Drain the coolant system to below the ECT sensor.
  3. Disconnect the engine coolant temperature (ECT) sensor electrical connector.
  4. Carefully remove the ECT sensor.
  5. Installation is the reverse of the removal procedure. Coat sensor threads with thread lock sealant and tighten sensor to 89 inch lbs. (10 Nm).
It looks like this:

Typically screwed into a coolant passage in the intake manifold or the thermostat housing.

1998 Saturn


Are youy referring to the coolant level sensor, or the coolant temperature sensor. The level sensor is built into the resevoir bottle and can only be serviced by replacing the entire reservoir. The temperature sensor is locate on the cylinder head on the right side of the engine (standing in front of the car, facing the engine. AKA the drivers side.) It is below the upper radiator hose toward the bottom of the head. There is a small two wire connector that plugs into it.
