Coolant Low beeping
 

I've recently (3 months) purchased an FCna, got down to the basics, checking fuses, changing oil, changing coolant, gas, etc., though when I start her up, I get this beeping noise after 30 seconds telling me my coolant is low, I know letting it run for a few minutes doesnt heat up too quick to cause damage, but I haven't started the car in a month because of that. Anyone have any advice on what to check for first?

Is the coolant level correct?

Yeah the coolant reservoir is just under max, running the car and added coolant into rad cap next to the upper hose, to the brim. still with the beeping, I ran it long enough with the heater on for 5 minutes, doesn't turn off, checked level and still to the brim, I hadn't driven it yet since the check, is there maybe air trapped somewhere?

Try bleeding the system, and making sure that the system is full, if there is a air pocket at the radiator it may show full at the cap but as soon as you pull the bleeder it will settle. My radiator has a plastic bleeder screw on the side near where the top radiator hose goes to the radiator.

and make sure the wire to the sensor on the radiator isn't broken.

Did you ever figure it out? I am in Woodbridge

I have had same issue on my '88 vert and I have had the car since its 'birth'. I just wondered if you figured out how to stop it. There is a thread about this issue and seems first thing is to open the air bleeder screw on the upper radiator hose. I have yet to confirm where that is but you can see my post on that thread too......
