Mysterious Coolant Leak

sterlinggrau530 · 02-07-2017, 08:43 PM

Hey Guys,

I purchased a 2011 X5 xdrive 35i. The car only has 31k miles. The car was driven I'd say roughly 50 miles. The car sat for a day and I was backing the car out of the driveway and saw a blue puddle. And it was Coolant. It wasn't a lot. The coolant level was in the middle. It is not leaking from anywhere in the top. Where could it be leaking from?

Cracked coolant expansion tank? Leaking water pump?
