21.3.1.1 Lycoming/Continental CHT Sensor Installation
Garmin sensor kits for Lycoming and Continental engines include Alcor 86253 Type K thermocouple
probes (Garmin P/N 494-70000-00). Refer to Alcor CHT Installation Instructions (P/N 59167) for
complete installation details. Engine manufacturer’s guidance should always be consulted for proper
location of CHT probes. A finger sized loop should be provided to allow sufficient strain relief of the probe
assembly, and care should be taken to make sure that no chafing of the wires occurs.
