McLaren's Eric Boullier added that the reliability problems they had in their pre-season testing were not linked, but added that these problems did not stem from a design mistake.
The new MCL33 had a shutdown problem due to an electrical problem once on the first day of the second test, but twice caused a red flag due to a hydraulic leak on the same day.
Fernando Alonso came on the track with MCL33 on Wednesday morning and was on his way to seventh bend because of an oil leak on the drive. The team decided that the Renault engine had to be replaced.
"We look at the car, we have some small problems that we have to solve, but we are just doing a test, which is part of the whole process."
"We have a very new partnership with Renault, we have a new design, this is a whole new package, we are just testing now, you have to give us time, everything is fine."
McLaren said there were no problems with the overall design of the package, while opening various cuts on the engine lid to prevent the exhaust heat from interfering.
"No, I do not think it's related," asked Boullier if the endurance problems were related to the extremely narrow packing on the back of the car.
"Obviously we are trying to design the best vehicle so we have to be sure of the concept of the vehicle, and when you try a new vehicle concept you have to see it on the track."
Now we have to make some adjustments and focus on the setup, but the leak has nothing to do with it. "" We have to make some adjustments and focus on setup, "he said. said.
Boullier said changes to the cooling system will not affect the update package in Melbourne, but these problems have had a negative effect on McLaren's understanding of the new car and engine.
"We are trying to make a plan, so now we have to look at how much time we have lost and focus on our priorities, so we will not be testing some things."
