Hello all, recently my low coolant light has been on. I woudl check the coolant level, it would be halfway down the neck of the resevoir. No biggie, probelm solved.

This was Thirsday, today it came on again, the colant level after being filled up, went down maybe a inch. The light does go off once the ignition is restarted, but comes on again a few seconds later once moving. Tempertaure gauge doesn't move, but it does have me concerned cause the RF cooling system and I have had a history.

Is there a problem or just 180,000 miles plus and a goofy sensor wanting to be known? Thanks

 

The coolant sensor might be going bad or just gunked up. Pull the sensor and clean it, that might help.

 

You say it went down an inch since last Thursday? Is it leaking anywhere? Sometimes the coolant light acts up when it gets dirty etc., its a pretty well known issue with these cars. But that doesnt mean ignore the problem, if there is one.

 

Get a new sensor.JMHO

 

Yup, they fail all the time. Pay $50 for a new one or just unplug it.

 

i had the same problem with mine, i unplugged it until i had a chance to replace it, but i never tried to clean it and that sounds like a good idea to try first

 

If the level is going down, it doe not sound like a sensor problem. Fill the radiator and the reservoir to the proper cold level and check it every morning when cold for a few days.

 

You have to check the level in the radiator, not in the reservoir.

 

probably a blown sensor. check shoebox's site he has a picture of where the sensor is located and instructions on replacing it. Very common part to fail.

 

Ditto that....check the level in the radiator when the engine is stone cold before startup.

 

Thanks again, great info, I will check all the angles. Thanks again for the help.
