I have a problem with my add coolant sensor .. the coolants full but it keeps on buzzing non stop ... 86 rx-7 .. i cant stand it any sugestions?

 

you probably have bubbles in your system
idle your car with the rad cap off, it should bubble and the coolant level should drop
add more as it drops

if you've already done this and you know the system is airfree....Shoppers Drug Mart sells some really nice earplugs LOL


good luck
