The low coolant level light keeps coming on on my 1995 camaro z28. I have replaced the radiator, thermostat, and coolant level sensor. That I know of, there are no leaks. What do I do?

Hello: If the light is for low coolant level and the radiator/overflow tank are full it will not hurt to drive it. The thermostat has nothing to do with the coolant level switch. The level switch will be in either the overflow tank or the radiator tank.

Did you burp the air out of the cooling system? That needs to be done if you haven't - air will trap the thermostat and keep it from opening. Check my tips and tricks for how to do this.

the car is heated at low speed because less air flows at high speed and does not heat because the air flows more, check if the fan is turning on and check if you have good revolution,, check fuses, check the thermostat temperature, clean radiator use antifreeze coolant and finally check the pulley on the water pump with its setting correct ajustment. and finally if you work on the motor over time, verify that the ignition times are in place,

Bad coolant level sensor in the tank. Look around the bottom of the reservoir and find a plug connection, unplug it and see if the light goes out. I think the tank has to be replaced dont think you get the sensor out. You could try by take the tank off and see if it will come out of tank but I dont think it will.

i had the same problem mine would stay on all day with radiator full and resivore full. i changed it out and sprayed some electrical cleaner in the connector and all is good

The coolant level sensor is contaminated. It happends over the years. You can try and pull it out and clean it off or just replace it. The sensor is located below the radiator cap,

There are a few things that can cause this. The fluid level sensor located in the radiator accumulates scaling over the years. The scaling prevents the sensor from detecting the fluid level. One thing you can try is to use a wire with alligator clips on both ends. Clip one end to the sensor area of the radiator and the other to the battery ground or engine block. Leave it in place for a few days and see if helps.
Let me know.

It sounds like your cooling system is becoming clogged with debris. Flush your radiator, replace the temperature sensor and the thermostat. Also, Griffin makes great after market high capacity aluminum radiators, a little pricey, but worth the money the event you have to replace the radiator due leaks and corrosion.

You might need to flush out the system and replace the thermostat.
