Just ten minutes before the end of this morning's free practice, Sebastian Vettel's Ferrari grinded to a halt at the end of the pitlane.
The Scuderia mechanics pushed the car back to its garage but a thorough inspection since has decided the team to change the SF70H's power unit.
Apparently a detected water leak, and the lack of time in finding its source, prompted the decision to replace the unit..
The team is scrambling to have him ready in time for Q1. It will be Vettel's third ICE of the year.
