Temp Guage Stuck at 180ish
Car off or on, the temp guage is at 180 and never moves. Any ideas? It just strated doing this out of the blue. Car is running fine and doesnt appear to be over heating or anything like that.
Thanks.
Thanks.

I've never understood this. I find it hard to believe that GM would put a coolant temp gauge in a car that doesn't work. I could see it being inaccurate and the temps it shows not being quite right, but being a "dummy" gauge that's there just for looks just seems like BS to me.

I have a auto meter one hooked up in my car and i can tell you that my cars temp jumps from 160 if driving in the freeway to 210 if stuck in traffic. The stock gauge does not move if your car is anywhere from 160 to 230 i beleive it is. It only moves up higher from that once your car reaches over 230 and by then your pretty much getting ready to overheat these aluminam blocks.

Ok, so I unplugged the sensor and the guage dropped to nothing pretty much, no response at all. I noticed that it actually moves but it never goes past 185. It used to fluctuate and all of sudden it is not. It would go to 210ish, the fans would kick on and the guage would trickle back down. Is there a secondary safety I can rely on if the car starts to overheat? If that sensor or guage is bad is there something in place to keep from spontaneously combusting into flames? It's not my daily driver but I'm not ready to do a rebuild just yet. Im trying to get axle bearings and little things like that in order before I start tearing into the motor. And ****...

The computer does see the "real" temp, but the gauge is hooked to the computer via a serial port connection (as I understand it). The computer interprets the actual signal, then sends the dummy temp reading to the instrument cluster. Either live with it or put in a custom temperature gauge - like most folks do...
Those are pretty much your altenatives without spending big bucks....

My temperatures never goes above 185 when cruising at all. I have a mid 98. It only goes higher if im setting for example in the staging lanes, but thats what fan switches are for. The 1998 ls1 owners manual says this is normal. I can take pics of it if you like. Change the ECT and if you still have trouble get a new thermostat. It might be stuck wide open... same issue I had.... It would heat up but never get past operating temperature.
