    How to service the Coolant Temperature Sensor/Switch for the computer on Ford Escape? Posted by Customer
    A:

First disconnect the electrical connector from the Engine Coolant Temperature (ECT) sensor before unclipping the sensor and taking it out. An inverted installation procedure should be used to finish the installation.

    Q:
    How to Service the Coolant Temperature Sensor on Ford Five Hundred? Posted by Customer
    A:
    Service of the Engine Coolant Temperature (ECT) Sensor requires starting with drainage of the engine cooling system. Full positioning of the brake aspirator tube into the air cleaner outlet pipe creates no vacuum leak before removing the positive crankcase ventilation and brake aspirator tubes. Disconnect the mass air flow (MAF) sensor electrical connector while also loosening the air cleaner outlet tube clamp at the electronic throttle body before tightening it to 5 Nm (44 lb-in) when reinstalling the clamp. People can handle the installation of their air cleaner housing since they don't need tools and should first remove the air cleaner housing cover with outlet tube assembly. The ECT sensor electrical connector must be detached while removing the hairpin clip and extracting the ECT sensor. Place the new sensor by following removal procedures while aligning the air cleaner housing cover to the air cleaner tray notches then applying clean engine coolant to the O-ring seal.
