As far as what is run off of it, you got it, fan, power steering and thats it. Did you notice any difference at all? Any difference in the steering? Sound of the cooling fan change?(fan drive) I have the replacement items to do mine, and I just need to do it this winter. I was told by a service tech that those filters and oil will last and perform way past service time in the manual( Probably not suppose to tell me that).......without worry or lack of performance. I don't believe mine have ever been changed also.....15 years! Still working fine. Going to get done this winter..........
Anyone on here that has done this service has not posted any differance in the system after doing this service that I have ever read........It is not a dirty service and the oil, only running 2 items, has a easy service. Mine is AW-32 and is still clean and clear, not dirty. .........I will see if any difference after my change, I am guessing not, we will see.
