Hi, I want to replace the coolant, transmission, rear differential and the transfer case fluids in my 2014 RDX, as the maintenance reminder B16 was turned on . Can anyone please let me know the genuine Acura p/n for these fluids and how the quantity I would need? Are the Honda oils/fluids the same and can be used in the Acrua? Thanks in advance.

 

Fluid capacity can be found in your owners manual.
you can find part numbers here: www.acuraoemparts.com

And yes, Honda is Acura.... And Honda has been using the same 6 cylinder engine since 1996

 

My opinion...based on growing up turning a wrench on a car as my dad owned an auto parts store for 30+ years, many years of car ownership and many years of Honda ownership

My understanding is Honda / Acura fluids are one and the same.

Coolant: use the factory blue...unless you're willing to do a complete a complete flush with cleaner to get rid of all remnants of the old coolant. Don't mix.
ATF: I'm sold on Valvoline MaxLife Dex/Merc full synthetic ATF
Rear Differential: Nothing but Honda / Acura fluids
Transfer Case: I would tend to go with Honda / Acura, but any appropriate gear oil should do
