pn#/source needed: temp sensor

[Phil Waterman]

Hi Bob

When I reassembled the 216 for the HUP with the replacement head the new head did not have the large diameter tap for the steam relief valve and the temperature sensor, so I ran into the problem you described of getting a leak free connection. I did find a solution for this problem with modern brass fittings, only problem is I can't find my notes or pictures of the parts. So next time I have the engine cover off the HUP I'll take a couple of pictures of the fittings and then I think I can match them to Weatherhead parts numbers. But it solved the problem of the CMP sender not fitting the new new brass adapters.

I need one of those step down adapters you described getting with the gauge the fitting alone was $14 while the gauge with fittings was $15 so I have an extra, cheep gauge on the shelf.

Will try and figure out the parts numbers for the 194?s GMC that matches and post it when I do.

Cheers Phil

It seems there are a lot of problems with these. My sending unit stopped working and because the system is 12V I thought I'd have no problem using one from a post war GMC engine. I got one that plugged right into the hole in the block and I wired it to the gauge. Nothing. It turns out the model I used was for the dash lamp warning system and not a gauge. It was either off or, when it hit 165 degrees, on. I'm still looking for one exactly the same but that works with a gauge.

since the actual temp sender works, i will make an electronic circuit to invert the signal and calibrate it.
will be easier for me reather than searching forever for the "proper" sender.
will be cheaper too since i have soo many electronic parts already.

thanks for all the reply guys, really appreciated !
