Temp gauge acting weird
So I've searched the forum and found nobody having the same issue as I am having with my temp gauge...I've recently replaced the gauge switch and still does the same thing...What's happening is when I start the car it seems to get to operating temp rather fast..(1-2min) and it seems to run a lil hot (about 3/4 of the way up on the gauge).. Here's the punchline while I'm driving, If i turn the car to the right, the temp goes down to normal, If i turn to the left, the temp goes up almost to hot... I've had somebody watch the gauge as i played with the wire/connector and it doesn't cause the gauge to move so what else could it be?? I've replaced the thermostat, temp sensor and gauge switch...the car has always ran at the 2nd mark on the gauge...I happen to notice it higher than normal last week...and it ins't overheating..Any input would be great! Thanks!

I say its the gauge. Mine did odd stuff like yours and i changed out the sensors. Got a new gauge and all is good. Price for one will vary depending on what year you have check online with Sewell Lexus.

I would be concerned that you may have an air pocket riding near the temp sensor, that needs to be burped out. The block probably overheats in that area because there is no water carrying the heat away, until you turn the corner and it sloshes over the sensor, cooling it temporarily.

having to hit the dash to get the tach/speedo to work is often an early sign of failing ECU capacitors
the 2 wire temp sensor (called the Engine Coolant Temperature Sensor) has nothing to do with the reading on the gauge, it is strictly there to feed information to the ECU - only the single wire temp sensor beside it gives information back to the cluster gauge
