ismellrealbad Posted March 18, 2003 Report Posted March 18, 2003 whats this do? water temp sensor? well whatever it is it was unplugged. maybe thats what was causing my temp guage to act retarded. Quote
Redfox340 Posted March 18, 2003 Report Posted March 18, 2003 On my 1992, that's the low coolant light sensor... you're having Tempreture Gauge problems? Hmm.... - RedFox340 Quote
ismellrealbad Posted March 18, 2003 Author Report Posted March 18, 2003 not only that but if it erratically shoots up to some insane number like 220 240 the heat will be cold (and i know its not that high). then when the guage drops to the correct temp the heat starts blowing warm. i noticed yesterday if it does this in park i can rev the engine and the guage will drop down, another rev, it will drop more, another rev and its pointing to the right reading. WTF? im gunna keep my digital camera with me. if it does this again ill takea quick movie of the dash Quote
Robby1870 Posted March 18, 2003 Report Posted March 18, 2003 What about your temperature sender unit? Mine went out and the temp gauge would read wrong all time, like I would start it and it would read 240, and then let it run and it would read 100. And it would fluctuate between the extremes all the time for no reason. Changed the sender unit and it works fine Robby Quote
Guest Anonymous Posted March 18, 2003 Report Posted March 18, 2003 That is the low coolant sensor. It sounds like there is air in the system. Is it leaking coolant? Maybe the radiator was shot and they replaced it and never plugged that in. That's when the air got in there. Maybe. Quote
grandprix104 Posted March 18, 2003 Report Posted March 18, 2003 My GP did that for a couple of months. It was kindof woerd having it say thwe engine was over-heating while driving in a snowstorm I had a new thermostat put in and a complete machine coolant system flush and put in new coolant. no problem since.

ismellrealbad Posted March 18, 2003 Author Report Posted March 18, 2003 ok i after i plugged it in now the low coolant light stays on.....i didnt happen to notice if the temp BS stopped though. there are no leaks and everything is up to level. still another WTF? Quote
SmokesGTP Posted March 18, 2003 Report Posted March 18, 2003 Yeah mine does the same thing with the temp. gauge can't figure it out. Someone probably didnt want an idiot light on when they sold you the car so they unplugged it. Quote
Guest Anonymous Posted March 18, 2003 Report Posted March 18, 2003 Maybe the sensor is just shot. I may have one here I can send you to try. There's nothing to changing them. Quote
ismellrealbad Posted March 19, 2003 Author Report Posted March 19, 2003 yeah that thing looks easy to replace but god only knows how much gm wants for that part so i could live without a low coolant sensor. PM coming Quote
Guest Anonymous Posted March 19, 2003 Report Posted March 19, 2003 $43 from GM and $23 from GMPartsdirect. Quote
