    I own a 97 540i and i had a new radiator and hoses put in and new expansion tank installed and after i put the expansion tank in about 1 month or so. I was driving it home and it lost speed! so i pulled it over and had it towed. the results where an blown engine???? How could this happen with out any warning lights or anything the coolant indicator read normal! now my warranty want pay because the said i overheated the car!!! I would never do such a thing to something i love and adore. Please if anyone can give me some advice or how and what happen please let me know.. Thanks...

    I have to add coolant every 3 to 4 months about 500 milliliters, the problem has existed since i got the car 120000 miles ago, I have had multiple attempts at fixing with different mechanics none of which have succeeded

    The check coolant light comes on even after topping off the system, but the level is higher. However after about a week the level will drop and I can see some fluid on the garage floor

    Piece of garbage radiators. Aftermarket is better. Tired of driving past the BMW dealer only to have the car drive itself in.

    Replaced all cooling hoses. Bigger problem is the hoses passing through the firewall and the minimal clearance between the three clamps. I switched to VW eared clamps with new hoses and no more leaks.

    Cracked radiator. Replaced with OEM parts. repair bill was $865.00. If I used an aftermarket replaement I could have saved about $200.00. Not sure I made the decision.

    Had a crack in the radiator. The dealer charged me over $2500 to repair everything. It was insane.
