14.3.3.1 Lycoming and Continental Engine Sensor Installation
General Installation Guidance – Refer to the applicable engine manual for proper location of the oil
temperature sensor. The sensor is usually installed near the oil filter.
1. Cut the safety wire and remove the existing vent plug (Figure 14-8), if installed.
2. To prevent galling of the threads, apply a small amount of engine oil to the probe threads.
3. Ensure that an unused copper crush gasket is present on the probe, and install the probe into the
engine (black side of crush gasket down).
NOTE
Crush gaskets can only be used once. A new gasket must be installed any time the probe is
removed and installed.
4. Tighten the probe to the torque as specified by the engine manufacturer.
5. Safety-wire the probe to the engine case as appropriate.
6. Connect the supplied connector to the appropriate inputs on the GEA 24/GSU 73 as referenced in
the G3X interconnects in
location in the engine compartment to provide strain relief.
