Vauxhall Cavalier 4x4 Transfer box Temperature Sensor, Removal & Installation & Oil Level Checking

Warning: The 4x4 transfer box (txb) temperature sensor is fragile and easily damaged. There is absolutely no reason to remove the temperature sensor unless it is being replaced. Removing the Temperature Sensor
701. With the txb cold, trace the cabling back from the txb sensor (Fig.2D) to its connector at the bulkhead (Fig.A & B).
702. Disconnect the sensor, remove the detachable plastic part of the connector (txb side - Fig.1D) and carefully withdraw the cabling back to the underneath of the vehicle - (Facilitates threading through the ring spanner)
703. Thread a 3/4" AF spanner over the cable to place on the sensor for removal. 3/4" AF Ring spanner. CAUTION: Check spanner is good fit.
704. Break the thread seal and carefully start to turn the sensor out. Be careful to unwind the cable as well, to stop it twisting and damaging the connections at the sensor. If you are removing a dud sensor this is good practise ready for reinserting the new sensor. Drip tray CAUTION: Make sure the spanner is square to the sensor - do not let it slip under hand pressure. CAUTION: Some txb oil spillage likely.
710. Installing the txb Temperature Sensor
711. Remove the detachable collar from the new connector and set aside - (Fig.1D).
712. Thread the 3/4" AF ring spanner over the cable. 3/4" AF Ring Spanner.
713. Wind up the cable and temporally tie to make it easier to handle while turning in the new sensor into position. Small nylon ties.
714. Treat the threads of the sensor with 'Loctite' and place the new/recovered copper sealing washer over the threads.
715. Carefully turn the sensor into position pausing to keep the cabling from twisting excessively, and tighten.
716. Pass the connector end of the cable up through the rear of the bulkhead, behind the tie bar and most other pipe work, to the bulkhead.
