Location of Temperature Sensor

mhudsonbsme · #1 09-28-11, 12:48 PM

I have a 1965 Cessna 337 Skymaster. I am trying to install F&M oil filter conversions instead of the oil screens, however, my skymaster seems to have the oil temperature sensors installed in the back of the oil screens. Can anyone tell me if there is an alternate location for these temperature sensors, and possibly include pictures for reference? I have attached a picture of what I currently have. In order to install the oil filter conversion, these have to be relocated as the STC does not include provisions for tapping the end of the oil filter adaptor body to accept these sensors.

Most have the temp sensor at the base of the oil cooler. if you don't have a plug there you may have to change the oil cooler adapter plate.

We installed the F&M adapters couple of years ago. Great system, they have been fantastic. As Kim indicated my sensor was in the oil cooler. I just installed the JPI and it has oil temp and used the port right behind the prop on the engine case. There is an plug right on top that can be removed with a hex key allen wrench. I will see if I have some photos.

Here is a photo of the front engine port and the rear engine port for oil sensor.

Thanks for the information! What JPI system did you install? Did you keep the factory oil temp gauge as well? Any chance you might also have a picture of the factory probe location on the oil coolers? I really appreciate all of your help!

I will check my photos and see if there is a photo that might show the cooler location.

I installed the EDM760, old school but money was a factor. I would have liked to gone to the full digital display but too involved. Everything factory stays. I did put in the fuel flow option which I really like.
