Copied and pasted from the 1st post in this thread:I am not disagreeing with you at all. I think that is a great mod and makes the stock gauge usable. Toyota really blew it with the factory configuration and this fixes that issue. My only thought here was that the gauge reads very hot yet no boil over or A/C kicking off? It just makes me think that in this case, perhaps the gauge is reading high and that another temp reading would help for calibration purposes. It would be nice to know what temp it is at when it gets to the red.
93-97 Coolant Temperature Gauge Modification
You now have a gauge that will move with all temperature changes within its sensitive range.
Full sweep peg to peg is 94°
Pegged hot 244°
Top of red is 227°
Bottom of red 217°
Center is approximately 189°
Cold line is 160°
Pegged cold 150°
I printed this and have a copy on my sunvisor for reference.
