In my 70 jeep with the Buick v6 the manifold port is 5/16 which will not be large enough for the temp probe to enter. Is there an adapter to to increase the size to 3/8 and allow for the probe to fit

It would be recommended to use the radiator hose fitting adapter kit. It comes in different sizes.

Thank you for your inquiry. The 2263 is not 3/8" NPT. See the 2275 linked above for a M16X1.5 adapter.

Thank you for your question. We do not have vehicle specific installation information. This fitting will adapt our mechanical water temp gauge to a 3/8" NPT threaded hole. If you have a port on your application that 3/8" NPT, this is certainly the correct adapter for you.

I can't remember exactly, but the fitting itself is 3/8 so the sensor I believe is 5/16.

Matt from AutoMeter · 6 years ago
Hi Mason, we have no specific information on your 1jz gte, but if it's similar in size to this 3-3/8" NPT, it's more likely an M16 x 1.5 thread, which was very common on Toyota models. The M16 x 1.5 adapter for our mechanical gauge would be model 2275.

Does this fitting fit in an Ls head 5.3 241 head's

Hi Kevo, thank you so much for contacting us. The port on an LS cylinder head is an M12 x 1.5 thread. You can use this adapter to install an electronic gauge:
https://www.autometer.com/electric-temperature-or-pressure-1-8-npt-to-m12x1-5.html
An air core gauge (short sweep electronic) will also require the 2259 shallow depth sending unit:
https://www.autometer.com/shallow-depth-electric-temperature-sender-250-300-and-340-deg.html
There is no way to use a mechanical temperature gauge with the existing port on an LS derived cylinder head without expanding the port. You'd have to use a radiator hose adapter for a mechanical temp gauge:

Hope this helps!

Will this adapter work with the mechanical water temp gauge in the autoguage 2349 console?

Hi Dan, thank you so much for contacting us. For an Auto Gage mechanical temp gauge, you'll want to use this 3/8" adapter:
https://www.autometer.com/3-8-brass-npt-mechanical-temp-adapter.html
The design is slightly different than the one we use on AutoMeter gauges, hence the different adapter. Hope this helps!
