Polo vivo 2013 coolant water

[Pri88vw]

Hey guys

I'm new on forum

Last week Sunday, i filled the water coolant up to Max, then i drove for a week to work and come back home, then the water went low, the engine is fine and oil is fine no mix with oil and water. Nothing leaking on the engine. What can be a problem when the water gets low ?

Thanks

Check the heater valve. At the back of the engine below the intake manifold.
Common problem.
Hope that helps
