ISO ECT Engine Coolant Sensor/Switch 1977 Cadillac Deville

[77Deville]

Hello, any suggestions of finding a part?

Looking for an Engine Coolant Sensor. Its for a 77 Deville 425 with EFI - Base 2 door Coupe.

Thanks in Advance

Peter,
I saw your post was over a month old without any replies. I think you are referring to the EL31 sensor which is no longer available. Mine is bad on my 79 Eldorado but I'm trying to come-up with a solution. Take a look at this link where I'm documenting what I'm doing (seems to go to the last post but it will get you to the topic at least):

It's too early to promise anything but the goal is to create a replacement. The electrical connector will be very difficult so if original look is important you should keep your failed sensor because it may turnout to be rebuildable if what I'm doing is close enough electronically.

Peter,
If you are still looking for that switch please PM me.  I found the one that came off my 79-425.

I did end-up finding OE connectors for these and I am now making replacement sensors. Attached is a photo with one of mine pictured next to my failed original sensor.
