In the radiator there is a sensor about 1/3rd of the way down from the top with 1 wire connected to it. When the sensor goes bad the low coolant light stays on. On our GM products replacing the sensor in the radiator turns the light off. The wire from the sensor to the dash light could have a bare spot in it and be touching metal witch would turn it on but I have never seen that yet. It would pay to check this also.
There is a low level sensor in the side of the radiator. They do go bad.
Check your coolant sensor for built up sludge, or the sensor may need replacement.
Add coolant to the reservoir. If the low coolant light still stays on, replace the low coolant sensor.
you can't reset it, fill your coolant up full, both rad and overflow. the light will go out. if it is still on when everything is full, then your coolant sensor is broken or unplugged. if you light goes off then comes on again and your coolant is low, then you have a leak. if you have a 3400 engine in your lumina common leaks are intake gaskets, waterpumps, and head gaskets.
If it is the low coolant light, it may mean your coolant is low. If it is not low, it may be the low coolant light sensor malfunctioning.
Reservoir light? You mean low coolant light. Low coolant level means the reservoir is low of coolant.
Low coolant level.
when u have low coolant
Coolant is low or a sensor malfunction.
The low coolant level light turning on suggests that there might be a leak in the cooling system causing loss of coolant. It is important to check the coolant level, top it up if necessary, and inspect the system for any leaks to avoid potential overheating issues.
maybe cuz its low on coolant
There is no way to reset the light. If the light is on, then either the coolant is low, the float is stuck or the sensor is bad.
