  Q:

  How to replace Coolant Temperature Sensor on Mazda Tribute?

  A:

  With 2012 models and older models featuring V6 engine specifically 2008 and below, start by removing the cable on the negative battery terminal and empty the cooling system. The second step is to take out air intake duct and find the ECT sensor on the thermostat housing. Unplug the electrical connector of the ECT sensor and unscrew the holding clip by drawing it straight up and then remove the sensor. Undo the old O-ring and always install a new one when changing even in the case of reuse of the old sensor. The removal is undone in the opposite sequence as the installation and once the cooling system has been filled, the battery should be reconnected to give the Powertrain Control Module time to re-learn its idle and fuel trim strategy to achieve maximum performance. On 2013 and subsequent models, also applicable to 1.5 L, 2.0 L and 1.6 L engines (with 2.5 L models again requiring just a CHT sensor), begin by dismantling the engine cover and emptying the cooling system. On models with 2.0L engines, disassemble the battery and the battery tray, remove the turbocharger piping between the air filter and the turbocharger inlet. In the case of 2.0L, loosen the two nuts attached to the engine keeping the purge valve and tube bracket of the EVAP. Find the ECT sensor on the coolant piping located at the back of the cylinder head, unplug the electrical connector and get rid of the retaining clip. Ready the new ECT sensor to curtail the coolant loss and when the same sensor needs to be re-fitted, examine the O-ring whether it is damaged. Installation should be done in reverse order, including the replacement of the old sensor of ECT with the new one, putting in the retaining clip, and filling the coolant, in that order.
