|The McLaren MP4-30 suffered a cooling pressure failure on Tuesday.|
McLaren was forced to retire from the third day of testing at Jerez after a cooling pressure failure on the car. The team managed 32 laps in the morning session making day three their most productive yet.
The problem forced McLaren to take the engine out of the car, ending the day's testing session.
"We've had a loss of cooling water pressure and have removed the power unit for inspection. That’s a long process, so it ends today's running."
The MP4-30 was being driven by Fernando Alonso when the problem occurred, according to a statement earlier today.
"The issue was promptly spotted by Fernando on an outlap - so quick to trace," the team reported on Tuesday.
No further details were given concerning what caused the failure, but the team is confident they will be able to run tomorrow for the final day of testing at Jerez.
"We can replace those components ahead of running tomorrow."
