Replaced water pump but cant find where to plug sensor back in


You didn't say what sensor, or whether it is 4 or 6 cylinder. Assuming you are talking about the water temperature sensor, it is located (from standing over the front bumper) on the top, right side of the lower intake manifold. You will see it by looking under the bulge of the upper half of the intake manifold, the part with the air passages. It mates onto the lower intake manifold, which has water cooling passages, making it an ideal location for the water temperature sensor.

How do I locate water sensor 1991 ford


There are two sensors; one for your dashboard gauge and one for the ECU (computer).

In the picture below, they are shown as the Water Temperature Switch and the Engine Coolant Temperature Sensor (or ECT) respectively.

Where is the tempurture cooling sensor located on a 1994 buick regal


The coolant temperature sensor is a thermistor mounted in the engine coolant stream. A thermistor is an electrical device that varies its resistance in relation to changes in temperature.

For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.

For MFI engines, the coolant temperature sensor is located on the intake manifold water jacket or near (or on) the thermostat housing.

How many temperature sensor are there on 5.2 liter


Also I have one 1993 Jeep Grand Cherokee 4WD 5.2L MFI 8cyl (nice SUV) this vehicle is not equipped with Engine Temperature Sensor; just have this...
- The Coolant Temperature Sensor is located: Under hood, center, upper engine area, mounted in driver side of water outlet
- The Temperature Switch is located: Under hood, center, upper engine area, passenger side of water outlet, mounted in intake manifold

Hope this helps (remember to rate this answer) and, if you need additional details or repair manualm juts send us a new message.

The tempertature gauge does not work on my jeep what may be the problem?


Could be the coolant temp sensor:

5.2L engine shown



To test it:

Perform this test on a cold or cool engine.
  1. Disconnect the negative (-) battery cable.
  2. Unplug the electrical wiring from the sending unit.
  3. Using an ohmmeter, measure the resistance between the terminal and the sending unit's metal body
    1. Infinite resistance or zero resistance: the sending unit is bad, replace the sender with a new one.
    2. Other than infinite or zero resistance: continue test.
  4. Remove the temperature sender from the engine.
  5. Position the sending unit so the metal shaft (opposite end from the electrical connectors) is in a pot of water. Make sure that the electrical connector is not submerged and only the tip of the sending unit's body is in the water.
  6. Heat the pot of water at a medium rate. While the water is warming, continue to measure the resistance of the terminal and the metal body of the sending unit:
    1. As the water warms up, the resistance goes down in a steady manner: the sending unit is good.
    2. As the water warms up, the resistance does not change or changes in erratic jumps: the sender is bad, replace it with a new one.
  7. Install the good or new sending unit into the engine, then connect the negative battery cable.
  1. With the engine cold, remove the ECT sensor.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the sensor resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.

What controls the temperature gauge on a 1990 ford f150 5.0 engine and where is it located


The temp gauge on the dash displays the information transmitted by the coolant temperature sensor. This sensor is located - on the engine - by the water neck. The water neck is where the top radiator hose comes across and connects to the radiator. This sensor can look like the one here:

Hope this helps.

Water temperature sensor location on 1994 Cadillac Eldorado


follow the top radiator hose to where it enters the engine block, you should be able to see it if you remove the hose, though getting it out will require a little more disasembly.

Heating System


The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

See Figures 3 and 4
  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.
