So I have a 1988 GXL, and occasionally while I'm turning (seems to be only to the right) I hear an "alarm" sound, similar to the sound it makes when why coolant is low and I start the car up. Logic led me to believe maybe the right turn was tilting the fluid far enough that it was tripping the "low" warning, but I've since filled the coolant right to the "full" level and it still does it.

Is there possibly another fluid level I should be checking that has the same warning noise inside? The check-engine light does not come on while I'm turning like it does if my coolant is low.. Just makes an annoying buzzing/alarmy sound on hard right turns (even some not-so-hard turns).

 

Oil level sensor is another possible cause. If your oil level is at all low and you are making hard turns the buzzer will go off. I have to over-fill my oil by ~0.75L when I do auto-x events to keep the buzzer from coming on.

 

Check your oil ASAP

 

My car did the same thing once when i left the window open and it rained really hard. Whoops. It went away after three or so days and i figured it was a connection being bridged by the water or something. Perhaps its an electrical problem
