Coolant Leak !!!

[briandwlee]

Thank you very much for your inputs.

My X is 2008 X5 3.0i.

Yesterday, the vehicle displayed the coolant low again. I left it overnight and refilled the reservoir with 2 qt of coolant this afternoon.

I did not move the vehicle in the afternoon, and in the evening, I opened the cap to see the level and found the level went down a little bit. I also noticed a little bit of coolant on garage floor, but don't know if it was from the vehicle. I might have dropped some when I refilled the coolant.

So, if it is not external leak and is internal, is the whole engine being affected or some parts f the engine, such as #1 or #3 piston chamber? If it's internal, doesn't the engine need complete engine oil flush to get rid of coolant residue?

I searched this forum and found some people had issues in their 2008 X5s with cracked radiators, and they said BMW knew the issues. A couple people mentioned that they had to wait more than a month for new radiators due to back order, and they said it didn't make sense that new vehicles were being manufactured with radiators, but that only service parts were back ordered. He was guessing that BMW caught the issue and started replacing radiators in assembly line, so BMW did not have enough parts for service.

Very frustrating.
