@Opie55 I called BMW Toronto (in Ontario, Canada), and I asked the BMW parts guy about coolant and how often I should change it, and IF I should, he recommends the coolant to be changed every 2 years. I also did some research and seen other BMW dealerships recommend BMW coolant flushed/refilled every 2 years… It’s up to you, it’s your BMW’s, that is good to hear! I always wanted a 650i!

@Kevink1 yes, I will not trust ‘lifetime fluids’ I’m sure that’s why BMW has it setup like that so they don’t have to deal with it…

Go ahead and do the transfer case/front + rear diff fluid changes! It’s worth it. I’m holding back on the transmission fluid change until 100,000k miles.
I got the transfer/front+rear diff fluids changed a couple days ago and it’s night and day difference - worth doing it! #KeepFluidsFresh

@carsbill I agree with you bud! It’s worth doing fluid flush/refill, it keeps your BMW’s happy, it may not be environmentally friendly…
Nothing is lifetime… only Tax, count, and death is guaranteed…

@Bdavi011 I agree with you. Only use BMW coolant… better safe than sorry.

@Dan13X3 I believe in preventive maintenance, and I want to keep my x3 for long as I can, and I want to keep it running solid 365/366.

My x3 is a 2017 and it’s at 115,000KM (71,000Miles), it’s a high mileage driven 2017 x3, so I feel like I should be changing the coolant, especially after I had to top it off twice in the past 2 years of ownership. (No leaks, I’m 100% sure)
