Hi,
Am currently experiencing coolant leaks on my volvo xc60 2010 2.0T whenever i turn the aircon off when engine is running. What could be the cause?

 

where is it leaking from? My guess is you are not seeing coolant but rather its the frozen condensation melting off the evaporator. AC is on, its ice. AC is off, it melts and drains out. If you never have to refill the coolant reservoir, then you know its condensation.
