I have tried the "Stovebolt Search" and could not find an answer.
I have what is supposed to be a 1955 2nd series 235 in my 1957. The temp sensor from my old motor does not fit the hole in the head of the "55" motor.The hole is too small.I bought a new one and it is the same size as the old one.
I tried to check the motor & head numbers to make sure the motor is really a 1955 235. I can't figure out what it is. Please help if you can. The block # to the left of the distributor is: 0512175F255X
and the head number is 3835913 GM24
If anyone can tell me so I can get the correct water temp unit I will be gratfull. thanks.

1955 was the last year to use a temp gauge with a tube. The 56 electric sending unit is larger and uses pipe thread.

Head number is a 1954-57 235 4-bolt rocker, small temp hole. Vendors like Jim Carter sell some adaptors for this but I think it is to go the other way. Sorry but the serial number I can't seem to find, what is the block # (cast in) on the other side of the distributor? Should probably start with 383XXXX.

0512175F255X

My guesses are:

F = Flint, MI plant
255 = 2nd series 1955
X = 3100 series

The number in front of the distributor is 3836233 and GM11 is under it.
The adapter from JC is the other way around. I guess I will have to get the smaller hole sensor, but how is that going to work in my 57? Will I need to by something else to go with it to make it work in the 57?

Thanks. I guess I will have to get the older small style temp sensor.

note that the 'older style' is the capillary tube that's part of the [mechanical] gauge, not a seperate piece like with the electric gauge - you need to find a good 55 gauge with attached tube

Why is it that nothing is easy with this project? headscratch

I have never seen this style so I don't know what it looks like or where I would get the other parts. Do I need a totally different gauge cluster now?

Bill,
I was looking at American Classic & Jim Carter for the capillary type & they are EXPENSIVE. If you know where you can get one I would be glad to pay you for it, working or not. I can put it in the head so I can start the motor & if it doesn't work I will have the core to exchange for a new one. Please let me know if you have one you would be willing to let go of. Thanks.
