• Installation Instructions
• EGT in a Nutshell

Screw-In Mount:
This option provides the neatest installation. Many engines now come with a hole already threaded for a screw-in probe. If not, threaded weld boss P/N 28113 can be purchased to retrofit an engine. Alcor screw-in probes are available in 7/16"-20 UNF thread common in Continentals or 1/4"-18 NPT common in Lycomings. Some probes are available with adjustable depth to accommodate different weld boss heights. The probe tip should be 3/4" into the tube. Screw-in probes are also available with a 90 deg bend or an 8 deg bend to allow for an engine design that will not accommodate the straight-in type.

* Adjustable depth tip
** Built in radiator
*** Adjustable depth tip and built in radiator

Clamp Mount:
The is the most common option because installation is easy and no welding is required. A hole is simply drilled in the exhaust near the mounting flange. The probe is inserted in the hole and a hose-clamp style clamp secures it in place. Clamps are available in various sizes to accommodate different sized exhaust tubes.

* Built in radiator
** Omega style male plug connector. Does not include fire sleeve.
