mchill07 Posted June 20, 2013 Report Share Posted June 20, 2013 on my 95' GP the low coolant light begins to flash if I let the car Idle at operating temp for about 5 min. This also happens when I'm in heave traffic. While driving under normal conditions the light is off, or if it was flashing it softly fades out after Ive maintained a steady speed. IIRC, the light is supposed to come on and be steady if there is low coolant, and not flash like it does. I have good coolant filled to the proper level. This is strange.

ron350 Posted June 20, 2013 Report Share Posted June 20, 2013 If your coolant level sensor is original remove it and clean the crud off the metal electrode. Quote Link to comment Share on other sites More sharing options...
mchill07 Posted June 20, 2013 Author Report Share Posted June 20, 2013 It is original, Next time I have a minute when the engine is cold I'll check it. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted June 20, 2013 Report Share Posted June 20, 2013 the MC was doing this last year.... only happened when it got hot out and the coolant was also up to temp. haven't bothered to deal with it since it hasn't been driven much since then.

mchill07 Posted June 25, 2013 Author Report Share Posted June 25, 2013 UPDATE: I removed the coolant sensor and found the probe covered in muck. Unfortunately, the neck with the o-rings broke off the sensor in the radiator. I was able to fish it out. Went out to the self pull and found a nice clean replacement sensor. After I got it in and topped of the DEX-COOL, I have not had anymore trouble. Quote Link to comment Share on other sites More sharing options...
ron350 Posted June 25, 2013 Report Share Posted June 25, 2013 Good deal. Those sensors are not easy to remove with the radiator in the car. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted June 25, 2013 Report Share Posted June 25, 2013 My Monte has been doing that since I've owned it Quote Link to comment Share on other sites More sharing options...
mhildebrand Posted June 25, 2013 Report Share Posted June 25, 2013 My light was on solid, ohmed out the sensor with a new one and it was bad. Replaced it, and a week later the light flickers when first starting the car when its cool and below 70 degrees outside. Soon as I start driving it goes off. Full of coolant too.
