BMW Complaint -
MICHIGAN -- LAST YEAR i a water pump leak and it was replaced under warranty. Now a hose came off the radiator and lost all the coolant while on the freeway. How can the hose, new and and securely clamped come off? This is a 540 '97.Some cause such as overheating , failure of the thermostat must have caused the thermoplastic on the inlet of the radiator to "melt". Who else has encountered this problem?
