Like an idiot, I added Coolant to the Power Steering reservoir. I did not drive the car, but did start it.
Since then, I disconnected the line to the PS pump and ran PS fluid through until it was draining clean. Reconnected and turned car over, but the reservoir is still contaminated.
I already had a mechanics appointment, and don’t plan to drive the car until then (1 week). I am going to have him do a full, proper flush, and change filter.
Question: Chances of real damage to pump and/or rack?
Nah, coolant’s not corrosive, and it should keep your rack from over heating!
The system’s going to have to be drained and flushed though. I’d probably do it a couple times. This video shows a good general method. I’ve used this on my VW. You can do it yourself to save driving it like that.
