Low coolant light on. I have a low coolant light on - no check engine light is on however. I have refilled the reservoir which did not help.
When that did not work, I removed the radiator cap when the engine was cold. Then I ran it until the engine warmed and the thermostat opened. I thought an air bubble could have formed blocking coolant.
The engine temp guage is normal and the engine is not running hot/cold.
Any ideas?
A few weeks ago I changed some other sensors including; cam sensor, knock sensor, oil pressure switch.
Is it possible that my engine temp/coolant sensor is also bad; where is this located? On the side of the block on the drivers side in front?
If I just clear any codes with OBD2 software will that keep the light off?

The coolant temp sensor is on the driver side head. The coolant level sensor is slightly below the radiator cap on the rear of the tube. Disconnect it to see if the low level light goes out. Mine did the same thing and I just left it disconnected because I was lazy.
If your level is full in the radiator then all is ok. the sensor sucks for the most part. I cleaned mine and it turned the light off. However sometimes its beyond repair and you can either live with the light or perhaps replace it. It does not effect the PCM in any way.
