SOURCE: 'low coolant"

Inside the surge tank is a float that turns on the "low coolant" light. As the float gets gummed up it gets stuck in the low position. I've had good luck in cleaning the surge tank out really well and ungummed the float so it slides up and down like it should.

Low coolant light won't go off


possible two faults. the wire to the low level sensor is broken in the plastic which is an indication of no water to complete the circuit. and the wire to the temperature sender unit is loose on the unit.

My low coolert light stay on. the gague shows normal oper, and has plenty of anti-freeze


Have you checked the coolant level in the overflow tank/reservoir? If the level is fine the sensor or wiring to it is probably faulty.

Low coolant light come on and off while I am driving or just starting. There is plenty of "water" in radiador and overflow tank.


Be sure the right coolant is in the car, orange colored Dexcool. I fthats good, then replace the coolant level sensor, in the right tank of the radiator. near the headlight. Of some cars its easier to replace the sensor if you take the headlight out.

Low coolant light is on but does not overheat and has plenty of coolant in radiator and reservoir


Those sensors are bad all the time. It is the sensor on the radiator tank. They have fingers on them that trap air bubbles. You can try tapping on it, but that usually breaks it anyways. The fix is to change the coolant level sensor.

Anyways if that helps you any little bit, then feel free to follow me on Twitter. That one is at: twitter.com/acoates23234

Thanks for the vote, and good luck!

Low coolant light is on but does not overheat and


There is a low coolant sensor down alongside the radiator. Either the wire came off or the sensor has failed. Other than the annoyance of the light being on if you keep an eye on the coolant level it will cause no harm.

Problem i have an audi a6 and my coolant light has come on


Check your coolant level. When the coolant gets too low this light will come on. If there is plenty of coolant and the light is still on, you probably need to replace the coolant resivouir because the sensor has gone bad. The sensor is located on the coolant resivour and must be replaced as a whole. You can find one for about 60 bucks and is a easy fix. You can do it yourself. Just make sure you replace the coolant with correct Audi coolant.

At high speed engine temperature is Ok, at low speed or idle it warms up to over half way and the coolant level warning light comes on. There is plenty of coolant, an new water pump and a new thermostat....


is cooling fan coming on?? the coolant level light pertains to a sensor that is in radiator side tank that is notorious for going bad you may have two seperate problems normal temp at high speed tells me the wind passing across radiator is keeping cool when stopped or in traffic as temp increases pcm commands fan to come on if it does,nt you will heat up

Low coolant light


When that happens it is usually because the coolant level membrane sensor is faulty.

Repair is not expensive, but must be done by a qualified mechanic.
