I see no bubbles but see condensation inside coolant reservoir. Changed coolant reservoir but same problem. Pic attached[/align] [align=justify]

Usally that much green buildup is a head gasket issue. It is green even if you use red coolant.

Any other possible reason for it except head gasket issue? Cold weather?
