Can someone tell me the thread size in the thermostat housing for the sensor? I want to add a temp gauge. Note this is for a Standard engine.
Thanks,
Jim W

I put a temperature gauge on my TEA20-80 this summer and I just happen to have the plug I removed from the thermostat housing right here. The external diameter of the threads is 0.623 inches (5/8, close enough) and according to my thread gauge there are 18 threads per inch. The gauges that I installed: oil presure, temperature, and ammeter were sold as a set and there were many adapter pieces in the kit, including the correct one for the TEA.

Hi Al,
Thank you! I see you're from Ontario; so am I. I was looking at a temp gauge at Princess Auto -where did you get your set?
Regards,
Jim W

I got my set of gauges from Canadian Tire. Originaly my tractor only had an oil pressure gauge, while it still worked the face of the gauge was half filled with oil, so I replaced it. The new kit gauges were the same size as the original one so it just fit right in the dash. I also had a hole, with a plug in it, on the right side of the dash and I put the ammeter in there. I then made a small bracket to hold the temperature gauge and mounted it to the bottom edge of the dash, so the gauge sort of sits in front of the ignition switch. This dosen't seem to cause any trouble for me and it is easy to reach around the gauge to the ignition switch.

At the hardware store buy a five inch length of threaded galvanized pipe of the same outside diameter as the inside diameter of your lower radiator hose. Buy a nut that will fit the sensor. drill a hole at the center of the length of pipe that the sensor will fit into. Weld the nut to the outside of the pipe, over the hole, splice this into the lower radiator hose with two clamps. Just an idea. Hope this helps..

That seems like a workable plan. However, I already have such a pipe and it has a block heater in it, so you can see that dilemma.
Also, since there is a place in the thermostat housing just waiting for the sensor, if I only knew the thread size, it would be much easier.
Thanks,
Jim

Jim, Who knows? I have tried everything under the sun to find out what thread that is. It's almost like an oil pan plug. I was going to drill and tap the plug and insert the temp bulb that way. I have seen posts that had wedged copper sleeves in it but I think the tapping idea would be neater. Either way it's tooooo cold here to do anything until spring.
Good luck and I will watch for other ideas from the guys here.

I guess if a person can get the plug out the threads can be measured, but then the tractor is disabled while you run around trying to find the right sensor bulb size, and maybe buy some adapters, from some teenaged kid behind a parts counter who who tries to tell you it must be metric. You get home to discover the various pieces really don't fit after all and during the time you were out you got two feet of snow that now needs to be blown, but just like at the beginning of the trip to town the tractor is disabled. All because you thought it would be cool to add a temp gauge to a tractor that hasn't had one in its entire 50 year life.

OK, somebody somewhere knows this thread size; we just have to figure out how to get them to look at this message board.

...maybe I should add a voltmeter instead...
