#13 of 22 Low coolant and check engine lights on
Mar 28, 2008 (6:49 am)
I have a 2002 GT and my check engine light is on and when i start my car after all the normal lights go off when you start the car the low coolant light stays on for a minute and my temperature gauge is all the way down. I think it's my coolant sensor but I've looked all over for it and I cant find it, any ideas on where it is would help. I know it should'nt be my thermostat because i just changed it 8 months ago and my coolant level is always where it should be.

I have a 1996 Grand Am with a 2.4 dohc. The coolant level light stays on even after I replaced the sensor. When I take the sensor out of the tank the light goes out. Whats up? Help me, anybody.
#15 of 22 Low coolant light and RPMs

I have a 1999 3.8 Grand Prix. My low coolant light is on also. Is the sensor in the low coolant tank? Also, about the same time my light started coming on I noticed that my RPMs are reving higher than normal. The car seems to be running fine.
#17 of 22 low coolant flashing
Jul 02, 2009 (11:19 am)
I took my 98 grand prix to the pontiac dealer for maintnance and they told me that my low coolant light was on. I told them that i knew that but i didnt know why because my water level was always fine. And they said that my low coolant level sensor was shorted out. So I went and got one and repalced it myself today. I started my car up and for some reason instead of it flashing like it was before now it just stays on as soon as i start it even when the car is still cold. Help if anyone has any answers, PLEASE!!!. I'm getting ready to just get rid of it and i dont want to.
#18 of 22 Is the Tranny in the Grand Prix the same as the Tranny in the GTP?

I'm a Grand Prix fan who currently owns a 97 GT, My questions is, Are the Transmissions in the Grand Prix & GTP the same? I have the oportunity to purchase a GTP that is having some transmission issues & I wanted to know before diving in over my head.
#19 of 22 Low Coolant Light on but fluid level ok

Disconnect the battery for a few minutes, then turn the key on but don't start the car. With the key on, pump the accelerator pedal 3 times, then turn off the key. Next time you start the car the light should be off, unless the sensor is malfunctioning. Replace the sensor if necessary, or don't replace it but check your coolant level often.

I have a 94 Grand Prix and the low coolant light started flashing. The sensor had to be replaced. However, the cooling system is very important because other fluids (i.e. oil and transmission fluid) are cooled by it. I would not ignore the warning light. Good luck.

The pedal trick resets the computer, which clears any codes and thus the warning lights. If it comes back on soon after reseting, multiple times, you know there is definitely something wrong or the sensor is malfunctioning.
