I want to change my power steering fluid. I got my 2906 Toyota Sienna at about 116k miles and now I’m at around 160k. I have no idea if it’s ever been changed, but I think it’s pretty dark and is slightly lower than it should be.

I was going to drain it out with a turkey baster like I see online, but I’m wondering if it would be best to have a shop flush it since it is so old.

Please let me know if there is any value to spending the $150 to get it done professionally vs the cost of the fluid and baster for doing it myself.

Thank you!
