Rochester 3080-38 Temperature Probe 3/8-24 NF3 250-550F

Its the exact same probe used OEM in my Mooney 231, and probably many other Mooneys. It fixed my intermittent CHT gauge problem. You have to be very gentle attaching the wire to it because the torque spec is only 3.0 in. lbs. I used a small auto point wrench to hold the top nut while tightening the bottom nut.

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: I am looking at the cylinder head temperature gauge for lycomings. The part number 3080-38 is for the probe. Is this a probe or the gauge you have listed on your web site?

We have updated the website to reflect the correct description. It is the probe that is listed on this page.

Q: Will this probe work for a 1965 Debonair 35-C33?

If you are replacing an existing Rochester probe 3080-00038 then yes as you had approval before otherwise no as it is not a TSO'd (certified) probe.

Q: Will the 3080-00038 work in a Cessna with original Stewert Warner gauge Cessna sender P/N S-1372-2?

No, this probe is only approved for replacing an existing 3080-38.

Q: Is this for a 12V or 24V system?

These do not connect to aircraft power. The probe connects to your instrument directly.

Q: When I search for Piper part number 553-673, this comes up. Is this the same part as 3080-38?

Yes, this is the same part.
