engine coolant light
I recently purchased a 2000 SL2 with about 50K on it. Great car, so far.
Yesterday, the engine coolant idiot light came on, but the temp gauge was fine. The light didn't stay on long, but has happened 5 or 6 times since and only for a minute or so. The owners manual doesn't say much about this situation. The coolant in the reservoir was just a bit below the min. mark when cold, so I added a bit to about midway between min and max. No light so far. Can this light mean anything else if the temp. gauge is OK. It's as if there is a sensor in the reservoir, but that's hard to imagine. Any ideas? thanks |

So I took it to autozone and had the codes read. It was for the transmission fluid temp sensor. So if there is a temp sensor for the transmisson fluid im sure there's a coolant sensor, it could be messed up. --- TROUBLESHOOTING P0711 The PCM has determined that the voltage signal from the transmission fluid temperature sensor is out of range for the current engine operating conditions. --- I never done anything about it and it just never came on again. Does your check engine light come on too? -Gabe |

Normally, the sensor for the coolant level is acutually screwed into the
radiator, (somewhere down one end or the other). If the level, while flowing, drops below this point, the "igit" light will come on. You may have coolant in the reservoir, but if after servicing, the light comes back on, you might want to pressure test your cap T. |

Fill the coolant bottle to the seam around the middle, and the light will go out, if that is indeed your problem. -- Visit the Saturn Performance Club - http://www.saturnperformanceclub.com |
