Where is the engine coolant sensor located on a 2000 ford f150 V8 4.6 L?

Here's a link to your part. Catalog Results 2010 Ford 150 Narrow By Engine Or Model Type Here's a Ebay OEM PART THAT IS CHEAPER. 8L3Z 6G004A Engine Cylinder Head Temperature Sensor Fits Ford Lincoln...

Temp switch - Under hood, center, upper engine area, front of intake manifold, driver side of distributor, mounted in engine block,
Coolant temp sensor - Under hood, center, front engine area, passenger side of distributor, mounted in intake manifold,
There is no water 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.

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.

ECT sensor controls the computer, engine coolant temperature sender controls the gauge. 5.0? 5.8? 4.9? Then I can tell you where it is.

The Coolant Temperature Sensor is located under hood, center, front engine area, rear of water outlet, mounted in intake manifold.

Hope helped (remember rated this help) Good luck.

its not a true coolant temp sensor. you are looking for cylinder head temp sensor. it is located on the driver's side head, at the front, on the inboard side of the head.

air intake look at snorkel it could be part of mass air flow check intake for eng coolant

temp control for cooloing system or heater sysem?

ECT - Engine Coolant Temperature Sensor

The engine coolant temperature (ECT) sensor (Figure 27) is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.
Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor.
