hello , my car is traverse 2009 , its power steering fluid no. 89021189 . but it is not available in iraq . some one advice me to use psf type ACDelco part no. 88865888 , please can you tell me is it compatible with 88021184
I think you'd be fine with any power steering fluid that does not say for "winter climates" or for "imports" like Honda, Toyota, etc. As long as it says compatible with GM vehicles, you should be fine. It doesn't have to be ACDelco. It's made by another supplier like Mobil or Petro Canada as they don't have their own refineries. They are just relabelers.
So in summary, use any quality brand power steering fluid that says "Compatible with GM vehicles".
