2.5 Install the Temperature Probes:

Install only the Temperature Probes applicable for your configuration.

A. EGT Probe Installation:

EGT Probe Installation:

Look at each exhaust stack and determine the best location at which all of the EGT probes can be mounted
at the same distance down from the exhaust ports. The ideal location is 1 1/2", but ease of installation should
prevail. Drill a 13/64" diameter hole in each exhaust stack. Insert the probe and tighten the hose clamp. As
the hose clamp is heated and cooled, it will become loose as it conforms to the exhaust stack. After the first
10 hours of operation, each hose clamp should be retightened.

IMPORTANT NOTE: For Cessna 210s or any aircraft having a slip joint in the exhaust system, install the
EGT probes ABOVE OR BELOW THE SLIP JOINT. Installing an EGT probe in the slip joint can damage
the probe.

B. TIT Probe Installation:

TIT Probe Installation:

The TIT probe should be installed on the inlet of the Turbocharger one to two inches before the Turbo-
charger flange. Look at each exhaust stack and determine the best location to install the TIT probe. It
should be routed away from the exhaust pipe and should not come in contact with other aircraft components.
When installing the P-110 probe, drill a 13/64" diameter hole in the exhaust stack. Insert the probe and
tighten the hose clamp.

If a P-111, P-112 or P-114 TIT probe is to be installed, perform the steps outlined in the “TIT Probe Depth
Adjustment Procedure” that comes with the TIT probe.

NOTE: After the first 10 hours of operation, the hose clamp on the P-110 probe should be retightened. As
the hose clamp is heated and cooled, it will become loose as it conforms to the exhaust stack.
