I was told by my mechanic today that the coolant leak dripping from beneath the car is from from a hairline crack in the radiator where it has corroded, however for the time being I have added an additive to keep the leak at bay until the radiator is replaced. He did tell me however it is a common problem on these cars.
I noticed that the OEM is made from BEHR, however they seem to have two different part numbers to the BMW OEM.
If so, can someone point me in the right direction?
A BMW technician will be carrying out the work for me but i want to make sure i have all the parts necessary for the new radiator to be installed.
Thank you in advance
