Where is the Coolant Temperature Sensor located, and How to remove and install on Cadillac Escalade?

On 6.0L models, the ECT sensor is located on the left cylinder head, in front of cylinder No. 1, just below the valve cover, while on non-6.0L models, it is positioned to the right of the throttle body, next to the thermostat housing. Begin by draining the cooling system to a level below the ECT sensor. For non-6.0L models, remove the air intake duct. Disconnect the electrical connector from the ECT sensor, then unscrew and remove the sensor. If reinstalling the old sensor, apply thread sealant to the threads; a new sensor should already have sealant applied. Installation follows the reverse order of removal, ensuring the ECT sensor is tightened to the specified torque. Finally, refill the cooling system.

The Coolant Temperature Sensor of Cadillac protects the health of the engine by monitoring and controlling the coolant heat at all times. In 1902 Cadillac came up and established its brand based on aggressive styling and steady performance that is never pushed. Drivers observe the clean lines on the bodies, comfortable cabins, and dashboards which provide clear information without confusion. Cadillac is also technologically advanced, with full-width touch screens and customizable glass roofs that illuminate cabins. The new battery-electric Celestiq demonstrates how the company has the tendency to bet early on innovations that the market desires in the near future. Cadillac retains comfort truthful, supporting soft leather with tight steering and suspension fine-tuning to please assured hands. The length of the highways is serene due to active dampers that flatten shocks and the lining that reduces wind and tire banging. The heritage of the brand remains, but all new models include USB-C, bright LEDs, and automatic updates available over the air, landing with little noise years into the future without the need to deal with drivers. The Coolant Temperature Sensor is mounted in the coolant passage of the engine, the thermistor quickly changes the resistance to heat and the control unit converts the signal to an accurate amount of fuel injected, changes the ignition timing to avoid detonation and head-warped cylinder heads, and activates the fans. When oddly high on the gauge, a faulty Coolant Temperature Sensor may cause rich mixtures, rough idle or limp mode within just a few seconds. A replacement of a worn out Coolant Temperature Sensor will regain the correct feedback, allow coolant to cool in the sweet spot, and allow the powertrain to relax on hot urban days or cold mornings.
