Exhaust Gas Temperature (K type EGT) Probes
Correct placement of EGT probes on the exhaust manifold is critical to obtaining accurate readings.
Placement differs between engine types, and even specific models. Consult your specific engine’s manual
for proper EGT locations.
ROTAX ENGINES (8250-034)
For Rotax 912 engines, only two of the four
cylinders need to be monitored for EGT.
Unlike the CHT probes, which are mounted
on diagonal cylinders, the EGT probes
should be mounted on the two rear
cylinders’ exhaust manifolds. It is critical
that the EGT probes be mounted to parallel
cylinders’ exhaust manifolds for proper temperature comparison. Recommended distance from exhaust
flange is 100 mm.
LYCOMING / CONTINENTAL ENGINE (8250-035)
Consult your specific engine’s manual for proper EGT locations.
WARNINGS:
A loose probe could allow exhaust to leak. This can lead to carbon monoxide poisoning in the cabin
and/or a potential fire. Have a knowledgeable mechanic inspect the installation.
The probe can come lose during flight, and could potentially come in contact with rotating engine parts or
the propeller. We suggest safety wire to keep the probe in place.
