Low Coolant Light/Buzzer

hey guys, i recently removed my air conditioning pump/plumbing from my 86 base model...and since then, when i first start up my car, the low coolant light comes on and it buzzes. but it only does this for like 5 min, and then it goes away. ive filled the coolant reservoir with the proper mixture of fluids...and its past the max line. should i drain and flush my radiator? what do you guys think?

Are you loosing coolant?
Maybe the sensor circuit is faulty?

i know this is an old post....but ive filled the rad cap up when its cold...and im still having the same problem. not as often as before, but it seems like it only happens when the car is on an incline (hill, driveway, etc). the coolant reservoir is well above the "full" line...so what could it be? faulty sensor/sending unit? its not that im really concerned about it, because i know it has coolant....but its just annoying hearing the buzzing as you drive

I had a buzzer problem and went through the flush and refill thing a while back. Well the funny thing is that it was the oil lever buzzer it is the same buzzer for that too the connector for the sensor was unpluged and kept buzzing. I fixed that and never have I heard tha damned buzzer again. Check that sensor it could be causing this. I had the same symptoms

Well the coolant sensor is on the top of the radiator. The oil sensor is on the oil pan. Do you know about rotary engines? If not you better start doing your homework.
