Brett Anderson recommends changing all hoses every 7 to 8 years. Should use only OE or OEM hoses too.Originally Posted by olsan100
The thing with BMW cooling system its probably best to change everything every 60,000-75,000 miles. EVERYTHING means Radiator (plastic), expansion tank (plastic), water pump, themostat and hoses. Am I missing anything?
Oh yeah, its also recommended to use BMW "blue" coolant (or any Valvoline Zerex G-48 equivalent).
