Coolant below minimum level stop engine safely I checked it at Volvo they didn't find anything wrong. What should I do?

 

If the coolant level is ok and the warning lamp is on - its probably the level switch. Simple cheap fix

 

No I am sorry I did not mention that the coolant level is low but not that low. I put like half a liter but it disappear everyday and the message keep on coming daily. Today I had a new one indicating switch engine off. I am really fed up don't know what to do and it does not drop. I also noticed that the engine was little bit unstable while I was putting the water. I put half liters and the coolant light turned off but I am sure it will come back again.
