Coolant temp sensor


this is a 97 lt1 out of a firebird with a t56. Im swapping into a 83 RX-7. I seen a video somewhere that this plug in the passenger side head between cylinders 6-8 is a coolant passage that i can use for a coolant temp sensor gauge. Hoping for someone to confirm this. Also sorry if this is a topic thats alread been brought up, i did some research but couldnt find much else other then the video i seen. Thanks in advance

 

That location works for a coolant temp sensor.

The stock location for the gauge coolant temp sensor is in the driver side head, between #1 and #3. Since the exact same head is used on both banks of the engine, when the head is on the passenger side, the hole ends up between #6 and #8, and they put that plug in it.

The coolant temp sensor that feeds the PCM is located in the lower part of the water pump housing.
