Maintenance fluid capacities?

stlb5 · 02-29-2020, 08:02 AM

Planning to do some service in the spring. I've searched but haven't found fluid capacities to know how much fluid to buy. Can someone please fill in the blanks? I have a 2014 N55 manual open diff. Is there a flush procedure for the coolant? Do I need extra?

Manual trans fluid -
Differential fluid -
Coolant -
Brake fluid-

Diff you fill slowly until it start to drip out of fill hole.

Coolant I think if you premix container of BMW anti-freeze with 50:50 distilled water that is enough to nearly top the system - you can hit dealer or buy more to get the overflow tank to MAX.

Brake fluid / I only know from using BMW containers, definitely have two bottles - and if you get a soft peddle on finishing you may want to bleed again so a third bottle ? Get opinions since one bottle is all some people use. But first siphon out reservoir and add forest fluid there. The reservoir screen dies pop off.

Manual fluid i had dealer do.

I believe I read on this forum and you SEARCH and I'll double check, that you must not over fill the coolant, it may have been recommend to not even go above the MINIMUM line in the overflow tank.

Yes, that's an excellent link. Been on that site before when someone linked to it from this forum.
