Coolant flush on 335

DASHOCKER · 01-19-2009, 02:05 PM

My car has 10,900 miles on the clock.. Car is being serviced today and the dealer is performing a brake fluid flush, oil change and fluid top off as part of the free scheduled service program..

When should a coolant flush be performed on an 07 335i sport?

AFAIK, coolant flush is not included into scheduled maintenance. It may have become another "lifetime" fluid. You can do it yourself though if you want, but I think it is perfectly fine to keep the original fluid for a few years. If you opt to do it yourself, find the description of the proper procedure. It includes "venting" and operating the electric coolant pump with the engine stopped.
