Temperature gauge sensor/'70 pickup
I'm replacing the old standard dash with a refurbished gauge cluster. The old unit just had an idiot light for temperature. The new one has a gauge so I had to change the sensor to one that talks to the gauge instead of the light. My problem is that both O'Reilly and Advanced Auto both sell a replacement sender that is too big for the port on my 1970 Chevy Pickup. It has a 307 which I guess is suppose to use the same size as the 350. Does anyone know why these parts stores are selling a unit for this engine that isn't the right size? Where can I get the right one? Thanks, Greg.

Re: Temperature gauge sensor/'70 pickup
I have a brand new a/c delco one here and it is GM part # 12334869 I would try the dealership to get the right part and they are really cheap. IIRC I paid about $10 for mine. Randy

Re: Temperature gauge sensor/'70 pickup
Thanks Mark and Randy. I'll check with the Chevy dealer tomorrow. It's just strange that the parts stores are selling a unit that doesn't fit.

Re: Temperature gauge sensor/'70 pickup
Are your heads original to the truck? If they are from a later year, then that might be why the temperature sensor doesn't fit. I had to mount my sensor in my thermostat housing because my heads are not the originals.

Re: Temperature gauge sensor/'70 pickup
Good point PJ, greg you may need to pull one of the valve covers to get the casting # off of it. Randy

Re: Temperature gauge sensor/'70 pickup
I just bought one from a board member and he said I would need a brass reducer to make it fit. Now I have to find a brass reducer.

Re: Temperature gauge sensor/'70 pickup
The correct sensor for a gauge should look like this, and should use a 13/16" socket to install.

Re: Temperature gauge sensor/'70 pickup
Thanks to all of you that have responded. I've pulled the old idiot light sensor and measured the hole at 5/8" diameter. The sensor that is suppose to be the replacement part fills a threaded hole that measures 3/4". The sensor I pulled has a number on it, "HS125CM 2639". I checked with GM and they say it's not their part. I've found a sensor that will fit but it is a Ford part so I'm guessing it won't work.

Re: Temperature gauge sensor/'70 pickup
Greg,
PJ has got the easiest fix for you, just plud the temp sensor hole up and replace your water inlet with one that will accomodate the sensor there. I know there are found on late model Chevy but I'm not sure what years to use. Hopefully PJ will chime back in and LYK what all he did to remedy the problem. Randy

Re: Temperature gauge sensor/'70 pickup
The stock sensor is 1/2 N.P.T. threads. It sounds like you have later model heads if the hole is too small.
