How do you find and clean the coolant sensor - dashboard light indicates low coolant which is not true?

The coolant sensor is located on the radiator about 6 inche directly below the radiator cap on the engine side of the radiator. Remove the battery to gain access to the sensor. Release the spring clip holding the sensor and gently twist and pull the sensor out of the radiator. Disconnect the wire harness to remove the sensor from the car. Dirt may not be the problem. The sensor electronics are "potted". The potting may have have cracked allowing coolant to short out the sensor. I recommend replacing with a GM brand sensor rather than the available Standard brand name. Wholesale pricing of both is about the same and the GM part is more reliable.

1993 grand prix that says low coolant when the coolant is full?
On the 2002 grand prix there is a sensor in the radiator about 6 inches from the top on the vehicles right side. It works based on electrical conductivity of the coolant. when it becomes dirty (doesn't conduct) or fails it will show low level. Remove the battery (for access) remove a spring clip (holds the sensor in) pull out the sensor and clean or replace. for the purpose of testing, with the sensor out of the radiator, but still plugged in and the key in run (engine off) ground the sensor to the battery. if the dash light goes out, the sensor is good. clean and reinstall.

The low coolant sensor is etiher plugded, broken, or your coolant is actually low. Check the radiator and resivor tank to see if they are full. If they are and the light is on, drain the coolant.

Clean it or replace it. then put everything back together.

PATH: Engine Cooling > Coolant Temperature Sensor > Removal & Installation Removal & Installation Drain the engine cooling system slightly. Disconnect the negative battery cable. Detach the wiring connection from the sensor. Remove the coolant temperature sensor from the intake manifold. Clean the sensor area of any debris. To install: Install a new sensor into the intake manifold. Tighten the 6-14 ft. lbs. (8-19 Nm). Attach the sensor wiring to the unit. Connect the negative battery cable. Fill the engine cooling system with a 50/50 coolant water mixture. Start the engine and top off the cooling system.
What if my low coolant light is on and I don't need coolant in my 2000 buick regal?
Take the coolant level sensor off the radiator & clean it out. The sensor is located passenger side under the radiator cap next to the battery. Best to pull the battery & headlight assembly. Metal retaining clip holds it into the radiator. I just took mine out for the same reason, found alot of "sludge" around the sensor probe. Cleaned it out with some sensor cleaner and soap, reinstalled, refilled the antifreeze and light is out.
Why is the Cutlass supreme low coolant light blinking?
First off, check your engine coolant tank. If it's low, then that's the problem. Put more coolant in. If it's at the correct level, then look to see if there's gunk buildup. Second, is your engine overheating? If the engine is not overheating, and there is gunk buildup in the coolant tank, then you may just need to clean the sensor. If there is no gunk in your tank, your coolant level is fine, and your engine is not overheating, then it may be a bad sensor, and you need to replace it.
What might cause the low coolant light to flash sometimes or stay on when coolant levels good and a new water pump installed on a 99 Monte Carlo 3100 The thermostat opens and the fans light off?
Defective low coolant sensor. Be aware that the sensor can be good but just clogged up. Have you ever put stop leak junk in your cooling system? If you did you have now learned a $50 lesson on what NOT to do to your car!! Sensor part #10096163 about $50 from GM. But first remove the sensor and clean it. See if that might save you from replacing the sensor. . . .
