I got a little problem, i add coolant, and the next day, all the coolant fills and over fills the overflow, why could this be?

Is your car overheating? Have you recently changed the coolant caps?

It can be either your thermostat or you have air in your system, as well.

Your Coolant temp sensor ok? You could be overheating and not know it.

You have 2 I believe. One for the ECU, one for the gauge.
