teperature sending unit

Here is one for the Archives...
I need a temp sending unit for my 361. I tested a few used ones on a stove top, but the resistance stayed high, so I think they are broken.
I went to the auto parts store, and got a correctly threaded one, however the electrical connection is a threaded rod, not the mushroom connector I wanted. i patched it together.
So now the temp gauge works..ibut t reads high, even though I just started the engine...
HELP!

I've messed with "universal" ones before and had similar issues. The problem is how the unit voltage level is sent or "interpreted" by the guage. I've always had to replace the sender with one of the same type made for the car....

I don't know really how they work, but I know I've had issues like that, which could only be solved by a direct replacement unit

nothing wrong with that price, but how can you be so sure that is the correct unit? There are others he lists for the same application...

Roger,

The calibration of the sensor is to the gauge for the model year, not to the engine. Water at 150 degrees in a flathead 6 will drive the gauge to the same position as water at 150 degrees in a 318. However, when they change the dash (and the gauge, or even to an idiot light) the impedence range of the sensor changes accordingly. There's only one sensor for the '59 dash gauge (what you're really concerned about), so I think that part should be OK.

Not that I haven't gotten incorrect parts from Andy! But he makes good on it. There's no ambiguity about there being only one correct part, though.

okay, I guess I was just rushing thru the books and confusing myself. Bernbaum offers the one unit...it is worth a try! Thank you guys.
I will order one up. (His price is lower than Len Dawson too.)
