Stumped on hot temp gauge reading - Lateral-g Forums

Move it to the passanger head on the rear. Also hook up a scan tool if the temp still shows a variation and read what the ecu is seeing. Pretty simple

I have the same setup- factory sensor in the drivers head, entropy sensor in radiator. I have found that there is about a 10 degree difference between the two. Is your radiator filled to capacity? It sounds like you have air in the system.

I don't think there is air in the system. I filled it up, ran the car and kept topping it off until it stabilized and couldn't see anymore air coming up.

Are you saying you have two sensors? One in the radiator and one in the head?

The steam is likely causing you the issue. I don't like the location for actual engine temperature either. You want to know how hot the coolant is in the engine, not after being cooled by the radiator.

That temperature sensor is for the fan controller. His temperature gauge is likely on the driver side head.

Pretty sure you have air trapped in the system based on your description of how you filled your system. You did not burp it....

That's not the how I interpreted above...

First off, thank you guys for helping me with all this. I'm new to all this so it's a learning process.

Here is a pic of the drivers side, is that also a temp sensor?

Where do you live? Maybe some one local can help

Any chance you have part numbers to make it work on the block? I tried searching but get overwhelmed with all the different answers. I found the correct M12- 1.5 thread with 1/8th NPT but when I screw in the sensor it doesn't come all the way out the other side which I assume means it wouldn't get a good reading?
