SOURCE: low coolant level in 2000 Grand Prix GT

I had the same problem this winter. The head gaskets were blown, took the block apart and replaced all the gaskets. Cost about 300 - 400 in parts and took one full day to finish with 3 men who aren't particularly experts but who aren't rookies to say the least.

Replace the low coolant sensor right side if radiator. When you replaced the radiator
they may have installed the old sensor.

I had the same problem.

Your problem is either a bad sensor or it could possible be low in the reservoir. Check the coolant sensor first. it is located on the radiator just below the radiator cap.

SOURCE: R reg Audin A6, heater stopped working mid-trip,

Put more anti-freeze in the radiator, your heater should start working, but there is most likely a leak, otherwise you wouldn't have had the warning light come on anyhow.

The coolant level keep coming on even though the level of coolant is ok.

I believe your problem may be your low coolant sensor(located in the overflow res.), they tend to get gummed up and quit functioning. Also before you chase that, be 100% sure your coolant level is actually full.

The heater is only blowing cold air.

The first thing to check is the level of your antifreeze (engine coolant) If it is low, the heater will not have any flow of the hot coolant to heat the inside of your car. If the coolant level is low, you need to find out why it is low. The coolantis in a sealed system and you should never have to add any to it. The only way it is going to be low is if there is a leak somewhere in the cooling system.

If the coolant is not low, the problem could be a bad thermostat. The thermostat controls the flow of coolant through the radiator and thus keeps the engine at operating temperature.

If the engine is at operating temperature and the coolant level is ok, then you probably have a problem with the blend-air doors or the controls for them that adjust the temperature of the air coming out of your heater and vents.

Blue coolant light comes back on and flashes? why

The light should be for a low level sensor in your coolant reservoir. Check your coolant level (when vehicle is cold), if fluid level is ok then the sensor is probably the culprit.

Low coolant light coming on

if the coolant level is ok then replace the low coolant light sensor, they are a real problem with these low coolant lites, the sensor is located in the side tank of the radiator, it is held in by a spring clip, very easy to change, u can also try leaning it 1st before replacing that often does the trick.

The coolant light keeps coming on but the car is not overheating. it does leak coolant every now and again not all the time.

it is the coolant level sensor that is making the light come on, your car does not have to be overheating for it to come on.
once the coolant level goes below the sensor it turns the light on.
If you fix the leak it will stop the light going on unless the sensor is faulty.
Hope this has helped.
