Wrong power steering fluid (did I really do this)!...🙈

ckracer76 · Jun 12th, 2019, 21:36

Hi all

Last night I was parking my S80 into a space and as I was manoeuvring and turning the wheels there was a horrible loud screeching sound and vibration coming through the steering wheel.

The sound got louder as I turned the steering nearer full lock (not a lot on the S80 granted...3 point turn more like 6 point turn) anyway I thought I'd better check the power steering fluid reservoir.

I popped the bonnet open and unscrewed the power steering fluid reservoir (completely ignoring the red letters printed in bold) WARNING USE CORRECT FLUID.

The reservoir screw cap has a built in dipstick with MIN and MAX markings and it was dry! I was horrified. How could I overlook this on my weekly checks.

It was 10pm so my first panic thought was all the car spares and dealers are closed. My next thought was drive to a my nearest Texaco fuel station and hope they stock power steering fluid. At the fuel station they had only one option Carlube by Tetrosyl Power Steering Fluid Red 1ltr £8.99 silver bottle. Suitable for most applications. I bought it and ran out to the forecourt to fill up my reservoir.

After a short drive back the steering noise disappeared and the steering felt lighter. All done disaster averted I relaxed and went back to work.

That is until I was telling my boss what happened and he said Volvo's don't take red power steering fluid they use green same as Volkswagen.

I choked on my tea!

What the hell have I done?
Turns out he was right. On closer bottle inspection I've put standard red power steering fluid in my car called Dexron III maybe also known as ATF? The green fluid I should have used is known as CHF11S. Carlube by Tetrosyl also make this and it comes in a black 1ltr bottle and it's double the price of regular red fluid.

Will it be ok? It all seems ok but this was only last night. Any advice greatly appreciated.

Sorry to be the bearer of bad news but nope, it won't be alright! Change it to the green CHF11S spec ASAP! There are lots of posts detailing various ways from using a turkey baster to empty the reservoir to disconnecting the return line and purging the old liquid. The red stuff causes seals to swell and could end up ruining your rack so don't delay!
Cheers,
Nobby

The CHF11S spec came in the owners manual in 2005.
Previos P2 years had ATF spec.

So I'd flush it back to the green stuff and probably no harm done in such a small period.

CHF11S is readily available for £10 a litre so not expensive at all.
My safe, quick and simple method is here.

My 2002 manual says to use Volvo fluid which is CHF.
I'll stick my neck out and say that all P2s use CHF regardless of model year.

Thanks for the responses much appreciated.

I still can't believe I did this. I should have known like engine oil there are different viscosity and specs.

My (poor) excuse for not checking the power steering reservoir level is because of all the cars I've owned not one has ever needed to be topped up. Ever. Somehow this has resulted in me not checking the power steering fluid on my Volvo during my weekly oil/coolant check, tyre pressure and washer fluid top-up.

This mishap has taught me a lesson. I can just see my father shaking his head in disgust.

Thought I'd share my power steering fluid ****-up on the forum in the hope it doesn't happen to somebody else.

As it happens my car is booked into my preferred independent garage for new front brake pads, brake fluid renewal, brake hoses and handbrake adjustment next week so I will ask them to flush and replace power steering fluid at the same time.

Cross fingers I won't have damaged the steering rack, hoses or reservoir. I'll report back next week.

If the level was that low there could be a leak anyway. Worth the garage having a good check to see if there was already a leak prior to changing the fluid

So the EU has different spec since I was referring the US owners manuals (available online).
They still have the same power steering system?

My car had dark ATF in it when I bought it 50k miles ago.
Replaced it with green and works fine so I'm just trying to say that the OP shouldn't worry too much about it, just replace it asap.
