Coolant level sensor

95 Grand Am 3.1. I replaced my coolant level sensor with an aftermarket one from O'Reilly auto parts. Anytime the coolant gets low and the light comes on, the only way I can get it to go back off is to replace the sensor again. I asked a GM mechanic and he said they are not supposed to work that way. The part has a lifetime warranty but I hate to keep replacing it. I would think the light would go off when you fill the coolant, but it stays on until I put a new sensor in. I have tried disconnecting the battery cable and reconnecting it but that doesn't help. Should this sensor burn out the first time your coolant is low? Anyone else had a problem like this? Thanks.

No the sensor should not burn out when it triggers. With mine I have to shake the air bubbles off the sensor once I refill it, then sometimes it takes a day of driving for the light to go off, shake the tank then drive it for a day checking the coolant level before you drive. Its a pain, but easier then changing the sensor everytime.

I tap the side of the tank on my car with the handle of a screwdriver, light usually goes off after a couple of taps, sometimes more.
