2004 525i

[Viper5569]

I was told that it is a smart thing to flush the radiator fluid out every 2 years. Is this true of the BMW engines? I've got a 2004 525 that I purchased from the original owner about 6 months ago and was thinking about doing this. Not sure if he had this done before. The car has 51,000 miles on it. Every day driver type car.

Thanks

they say every 4 years on coolant and 2 on brk fluid. but on most bemmers something in the coolant system breaks so the coolant gets changed anyway before the 4 years.
