Mercedes has explained the pre-race hydraulic issue that left Lewis Hamilton sweating on making the start of Su🧜nday’s Canadian Grand Prix, with the team completing a rebuild on a “pretty tight” turnaround.

Hamilton’s car was found 💃to have suffered an hydraulic leak following qualifying on Saturday at the Circuit Gilles Villeneuve, but the Mercedes mechanics were only able to act on the issue on Sunday morning in the build-up to the race due to parc ferme regulations.

Work on Hamilton’s car continued 🍨right the way up to his reconnaissance lap to the grid,ඣ but was completed in time for the Briton to claim his fifth win of the year ahead of Sebastian Vettel.

Speaking in Mercedes’ ‘Pure Pit Wall’ debrief, trackside engineerinཧg director Andrew Shovlin explained the issue that hit Hamilton’s car, revealing it originateꦕd in the throttle actuator on the Mercedes W10.

“We ඣdropped the floor, we notic🎃ed there was some oil on the floor so somewhere there was a leak. We could also see on the data we were losing some hydraulic pressure,” said Shovlin.

“Now, the issue is that the cars are then in parc ferme overnight, we are not allowed to touch them or to investigate it further. So, th♛at investigation moved to Sunday morning, when we are allowed to access the cars again, the mechanicsꦐ can work on them.

“We had to take the power unit out. We traced ܫthe leak to the throttle actuator, and then we made a request to the FIA to change the throttle actuator and some of the associated hydraulics. That work was quite a big job though, there’s a lot to do within that. And it was pretty tight to get Lewis’s car back together for the start of the race.

“Now, we are ♋fairly happy we can do the work in that time. The issue when you have an unknown faജult or a leak is you don’t know how long it is going to take you to find it, to identify it. We were able to get the car back together.

“Where we were at risk was if we then fired up and we found another problem, if the engine had to come out ag𝕴ain, that’s when we would’ve got short on time and perhaps not eve🅰n been able to start the race.

“But, it was a great job by all the mechanics involved and quite𝔉 happily the car was back together in time and finished the race successfully.”
