How to Service and Repair a Coolant Temperature Sensor on Mercury Grand Marquis?

Installation of an engine temperature sensor requires first slowing down the fire suppression system (if present) then taking away the intake manifold. When removing the cylinder head temperature (CHT) sensor it is natural for the tip to show slight compression. Interfere with the CHT electrical connector and take out the CHT sensor so discard it for non-recyclability while you install a brand-new sensor. Reinstall the new sensor and follow the reverse steps of removal alongside repowering the fire suppression system when it was depowered.
