1997 BMW 540IA User Comment / Complaint

The radiator hose connection at the top of the radiator failed completely. it is made of plastic, and split under cool weather conditions. this resulted in replacement of entire radiator, and replacement of radiator overflow container. it would appear that the use of plastic in this application resulted in heat stress over time, eventually resulting in complete failure without warning. possible engine damage still being assessed at this time. i understand that this problem has occurred too many customers, however, the factory replacement parts appear to be exactly the same as original. therefore, i can expect total coolant failure again in the future. this seems imprudent, and i have no response from bmw on this issue.
