Adding a Temp Gauge

As most of you know, the 84 turbo bird doesn't have a temp gauge. I want one in mine for obvious reason.. So i get my gauge and a pillar pod, do everything inside, run my wires, and install the sensor in the heater core line. After running the car for awhile I realized the temp wasnt rising and the line was cold.. Is there a valve that stops the coolant from flowing unless the heat is on? Where would a good spot be to place my sensor?

Please and thanks

I'm guessing that the sensor needs to be grounded, like in the block and maybe your new sensor is not????
When I did my aftermarket gauge, I just put the new sensor in the old gauge sensor hole. Don't use teflon tape on the sensor.

My particular sensor is a two wire sensor. I was thinking it needed grounded but that isn't the case. I tried swapping the wires and got the same thing still.. I could locate the idiot light switch and use that hole i assume.

To answer your original question, there in no valve in the coolant lines to the heater corw. Coolant always flow thru the core UNLESS the core is completely plugged up.

If you want to cut you hose Glow Shift has a really good adapter. That's what I used.

Thanks Jeff! I don't believe the core is plugged but it is a very good possibility. I mean the car did sit for almost 13 years..
