bro, there are even w204 merc having caltex atf in there steering systems. It works perfectly fine. I am just saying cz as far as i know u want the car in high perfections thats y if u spent couple of lacs on other things just spend two thousand more here.
It dont need to ne changed as even INH guys use atf INH guys use Atf in steering assembly.
But if u go to pefections then use Pentosin CHF amd change the radiator fluid with glacentine coolant, changed when i bought but change again, because once the mechanic wasted some amount while changing the power pump, he removed the hose..
Remember, dese both jobs are just for perfection and art of maintaining a vehicle. They are not necessary for the vehicle. This one is having a rack without sensors, and it doesnot need that fluid even but u may change it.
and the bleed is only required in the cooling system not in steering assembly.
and doubt you hardly driven more than 500km. so i doesnot even effect if dere is an engine oil in the power steering oil bottle
