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

[Georgeandkira]

Most everyone else here, and on every other Volvo board, has already heard this tale.

A 1999 V70 base was my first Volvo. The PO's mates at the "work garage" tended to his car. Some red ATF they added caused a growling which induced him to sell the car.
I flushed it with the proper green CHF-11S and the noise went away for ~40,000 miles.
Then, at highway speed on a temperate day, the pump growled softly-to-loudly over a 30 second time frame.
The $40 junkyard pump I found (true bargain) was from a '99 and dripped green fluid.

The mistaken "red fluid" spec remained in {No. American} Volvo owner's manuals for a long time. I even contacted Volvo about it.

I don't know how long Mr. Previous Owner ran the bad fluid. As mentioned above, get on this job.

As for beating one's self up for adding incorrect fluid? Remember, only the mediocre are always at their best
