Hey ,I check my car this morning before I start it and I see that the water it's in the miniment level ,so do I have to add more coolant on it ,if yes witch one? ,and it must be 50/50? ,and then how I must do it ? It's in the morning when the car is cool ,? Thank you

 

Please provide your vehicle info. Year, engine, etc. Where are you seeing the coolant at minimum level? The overflow bottle? If that is the case, then it is supposed to be at minimum when cold. Check your owners manual for the specified coolant type and how to properly check the coolant level.

 

2010 ,3.3 v6 ,when it's cold the level it's in the minimum, but after I drive it like 30 minutes I check again it's in in the middle between min and max ,I check in the manul I could not understand anything ,help me plz

 

It's perfectly normal. The level is at minimum when the engine is cold because the coolant is sucked back into the cooling system. As the coolant heats up while driving, it expands and enters the reservoir. Google how cooling systems work for a better explanation.
