R32 GTR water temp guage reads false

[t01-100]

I've tried to different gauges, but both read 'warm' in normal conditions. my mechanic tells me that on the dyno and road its running normal temp so maybe a gauge problem. its currently running new motul motocool fluid so certainly shouldn't be too warm.

anyone heard of this before?

yeah, my GTST guage reads false also. The other guages you tried, did you just run them to the original sender or did they come with their own?

Try going to an electrical outlet and buying a multimeter with a thermocouple. Set it up in the top hose and go for a drive. If it is under 90 degrees then it should be fine. Anywhere between 76 and 90 in tropical climate. Hobart might run slightly cooler.

Try replacing the temp sender if you have not already.
