Low coolant indicator!!

Low coolant indicator!!
Checked the search and it was no help. My low coolant indicator keeps coming on. A friend told me the sensor probably has a little buildup on it and I just need to clean it off. For the record I checked the coolant levels and they were fine...no issue with cooling either...coolant is fresh as of 6 mo. ago with Dexcool. Car operates well within normal temps 180-210 on a 80 degree day in traffic. I need to know where the low coolant sensor is. I know where the temp gauge hooks up to the drivers side of the engine block but where is the low coolant indicator sensor located so I can either clean it off or replace it. Thanks!!!

It's a few inches below the radiator cap - can't miss it. You can try cleaning it, replace it, or just disconnect it and the light will stay off. My car doesn't have one - GM did away with them on our cars in 00.

I have the same thing on 98 Z28 with the low level light. I can see the place you are talking about just below the radiator cap. Does this sensor penetrate the radiator? Can cleaning the sensor be done without partial draining of the radiator?

At least your '98 gauge actually works.

my sensor was getting gummed up with an oily substance, and giving a false coolant low light. cleaning it fixed the sensor, but the problem returned. Once the problem got bad enough it was easy to trace the problem. The power steering cooler, a pipe in the upper radiator hose, was leaking power steering fluid into the cooling system. I couldn't figure out where my PS fluid was going. Pressure tester on radiator confirmed the problem by showing bubbles in the PS reservoir. Replaced the PS cooler, flushed cooling and PS systems, case closed. no more false low coolant light.
