Hello,
I must use ATF fluid in my power steering but it is really impossible to know which one to use since I have always contradictory information. I own a 1997 Volvo S40.
- My manual says to use ATF (no spec)
- VADIS (program used by Volvo dealers) say to use ATF type F or G and that Pentosin CHF11S may be use for cold climates. Somewhere else in the program it say to use ATF type F,G, Dexron D/E Mercon........
- Volvo dealers only sell Pentosin CHF11S now for power steering. They no more sell ATF type F,G.
Well quite confusing no?
My problem is that if Volvo states to use ATF type F, it's maybe that my power steering pump is clutch driven. In this case pouring the wrong fluid may be bad. I forgot the idea of using Pentosin CHF11S as my car is now 220'000km and has run only on ATF for that time. I don't want to use that Pentosin thin stuff now.
So basically I have two choices: use ATF type F,G or much more common Dexron III for example.
Do you think it is risky for me to use Dexron III if my system requires really ATF type F? Nobody can tell me what the right stuff to use. Moreover I heard that Dexron ATF shouldn't be mixed with ATF type F!!!!!!! I'm really really confused.
3 questions:
- If my manual say to use ATF witout any specs, then I should be safe if I choose any ATF no?
- If Pentosin CHF11S (a true power steering fluid, not ATF) can be used for cold climates, this means that my pump is not clutch driven and so I do not require to use ATF type F no?
- If my car has run on ATF type F for the last 220'000km, may using Dexron III ATF affect seals in the power steering system or are all ATF compatible with any seals?
