Dashboard temperature gauge.

I'm just wondering where abouts the needle sits on the gauge when the engine is at normal operating temp.

The needle in my car never gets any higher than this, my first thought was that the car wasn't reaching operating temperature due to a faultly Thermostat (stuck open) but I have just replaced the Thermostat and it has made no difference.

I let the car idle for 20 minutes this afternoon and it never moved a millimetre.

 

Do they all sit here or is my gauge a bit duff?

 

The cars a 96 U.K. T.T. auto.

Mine sits bang smack in the middle

Mine used to sit in exactly the same place mate - it's slightly higher now as I removed and replaced the needle when I replaced my dial faces - nothing to worry about :)

Mine too. I beleive normal is right in the middle.

Middle for me too.

Mine's in the middle too. Could be the sender unit going a bit flakey.

 

There's a resistance check you can do to check its not the sender. It should give a desistance of 2 to 3K ohms at 20 deg C and 0.15 to 0.3K ohms at normal running temp.

 

I guess yours is reading 0.4 to 0.7K ohms at hot if its faulty.

The temp gauge on a Supra is notoriously unreliable. They only start going up when there's something seriously wrong!

 

I would guess that either, as you say, the thermostat has been removed so it never quite gets up to 'normal' temperature, or a lazy gauge, or maybe the needle has been removed and re-fitted incorrectly in the past.
