Radiator Flush

[MRol]

I've had my Z4 for nearly six years now, and it is booked in for an Inspection Two Service, and Brake Fluid change. I've been told that the radiator fluid shoud be change at this point. No mention in the Service Booklet about it. Have others had this done on their services around six years old at 65000 mile?

If I recall correctly, there is no mention of it in your booklet because it's ''lifetime'' coolant that doesn't need replacement. I just don't know if that applies to all years/versions of Z's.

It's not covered under Inspection II as far as I know, but I do recommend flushing the coolant at this point along with a brake fluid, differential fluid, and tranny fluid changes.
