Coolant problem Buzzing

Have a 1987 rx7 and just spent 1300 to get coolent problem fixed, or so I thought. When I am driving and slow down the buzzer goes off. Opened the hood and collant is showing low but the over flow is right to the top. Looks like its not getting sucked back down to the tank. Any suggestions. It was at a Mazda dealer. They said problem was fixed. Already replaced the sensor.

If the engine is hot it’s normal for the overflow bottle to be full. A guess is they simply didn’t burp the system completely and you have some air in the system. Leave the caps tight, let it cool completely. Remove filler cap, fill with coolant mix, squeeze radiator hoses a few times (you may see bubbles and level will drop), refill with coolant mix, replace cap. Make sure overflow bottle is at the proper level on dip- stick. You may have to repeat a couple times after driving and cool down.

i think 1300 is a bit much even if they had to replace everything. what all did they claim they did? for that kind of money, any continuing issues with that system would mean returning to that shop til i was satisfied that all issues were resolved.
