Hi, do any of you know specifically which Pentosin power steering fluid is the right one for an 02 s80? I have heard that there are 3 or so different varieties and I was wondering which was the right one to use..

Next, I am planning to install an inline magnefine filter on the power steering line, but I decided it would be the ideal time to swap out the fluid. What method would you all reccomend? Just siphoning the fluid out of the bottle and replacing with fresh (performing this procedure 2 or 3 times) or possible disconnecting the outlet hose and connecting a clear plastic hose to drain the system (while pouring fresh power steering fluid in)

What do you think is the best way and how much fluid can I expect to need?

Thanks

 

i did this on my older car by just using a turkey baster and emptying the bottle out, and refilling, a few days later did it again

dont remember the name of the pensodin, but the bottle was green i think you can use ATF, no ?

 

Nah, ATF isnt reccomended on these cars.. supposedly cause the seals on the rack to leak...

I know there are a few pentosins CHF 202 is one of them, (silver bottle blue writing)
Then there is the pentosin CHF 11S (green bottle)
There is also Pentosin CHF 7.1 (silver bottle, green writing)

I seriously dont know which is the right one...

 

my mech looked it up somehow at his shop, can remember, i know the bottle was green and white, sorry - call the dealer

 

I think it was CHF 11s. I do not recall if this is the most recent specification as what ever was originally in my 2002 S80 has since been upgraded. It is not ATF, the manual is wrong. Pentosin CHF 7.1 or CHF 202 is either the predecessor or sucessor to CHF 11s, the other one is not what you want. Call around and go to the auto parts store. The bottle will tell you which one succeded the other and the third is odd man out. It is green.

Good luck

 

This is also the same stuff as OEM.

 

Well the thing is, I can get the pentosin as cheap as about $14 or $15 per bottle, I just needed to know which was the right one.. I would consider calling up the stealership, but they woul tell me to "only use genuine Volvo power steering fluid" and we all know how that goes....
If any of you know which is the right one, will be much appreciated..

Thanks

 

I can try to find out on Tuesday if you do not know by then.

 

Just reading another post and I believe it is the 11S that you need.

 

Thanks tech, if you can just verify on Tuesday I will appreciate greatly..

I was looking at the way the bottle is designed.. Where would you reccomend I put the in-line filter? On the lower pressure upper line leading into the top of the bottle? This seems MUCH easier than going for the lower line..

 

The upper one should be fine.

In a 2002 S80 they put in CHF 11s but CHF 202 is the upgrade and I think it is what my dealer uses/recomends. Do not use CHF 7.1

 

Well thats what has me in doubt... I heard from one of the parts sites that CHF 202 is the correct thing but others say 11s. Whatever is the absolute best fluid is what I will be going with..

 

Took a look at my fluid today, and while it doesnt look particularly dirty, i did observe that it is a sort of brown with a slight golden look to it.. this is the opposite of what i was expecting seeing as the power steering fluid is normally blue or green or one of those types of colours....
Also interesting is that the manual says that its fine to use ATF in the power steering system.. something that I thought supposedly causes seals to leak..

Capacity is .9l so I guess two bottles of pentosin fluid should do the trick by whatever means I decide to use..

 

Called up FCP and they confirmed CHF 202 is the right fluid.. I ordered two bottles for about $16 each including shipping...

Im a bit worried though because if I lock the wheel all the way to the right, I get a sort of grinding noise almost.. and its not the wheels rubbing, sounds like the power steering pump to me, so i'll handle that flush ASAP

 

when i was buying my volvo i test drove another and it had that same issue when you locked the wheels left AND right, dunno what it is but it sounded like rubbing actually, better keep an eye on that

 

well, I know about the rubbing at full lock, that happens sometimes with the car but thats just bad steering stops, ive experienced that before.. but this is something new with the car and only when locking full right...
As soon as that fluid arrives im going to handle a flush and see if it helps.. I really hope its not my pump or rack or something expensive goin bad..

 

Everyone I ask says not to use ATF but my owner's manual, under power steering fluid type, says ATF. I'm confused, I really don't wanna pay over $20 for a bottle of Pentosin. Oh yeah, my car is an '02 S80 29. Anyone else drive this car? If so, what fluid do you use?

 

i did this a couple days ago if it helps anyone

jacked up the car and removed the return line and added a splice and a clear tube to a bucket
you turn the wheels 20 or 30 times and it pumps everything out
and with the line still in the bucket start adding the green 11S
there is also a 202 version which works but its not as good and there is a 7.1 DO NOT USE on anything newer than 1999 and in that case just use ATF fluid

it will take 1 can but if you want to rly flush the system get 2
have someone start the car as you add fluid till it runs clear and green re connect the hoses and your good repeat the rotation of the steering wheel 20 times to work out the bubbles
