Mystery hose

[Brian in Tucson]

What year is your car? I'm in the midst of a complicated engine change on my 2001 base.* Neither of my PS pumps have an overflow hose, never heard of such a thing.
The only overflow hose I've seen on my car is the coolant reservoir overflow--which exits behind the right rear tire.

Before you started your work, did you notice any puddles?



*I'm putting an engine set up for manual transmission into a tiptronic car--requires switching wiring harness.

Brian, the car is a 2000 S (3.2L). No, I didn't notice any puddles. I just noticed the hose dangling under the crossovers and wondered what it was. I had not worked in that area so I knew I didn't inadvertently knock the hose off a connection.

Have you considered just following the hose from the bottom up... or to wherever it leads? That might solve the mystery.

Yes, I thought about following the hose up. However, it is buried under the crossovers so it would mean pulling parts off....something I want to avoid as I have other fish to fry. I may change my mind once I finish my clutch/IMS/AOS project if I get a CEL. I now see that the parts catalog shows a "breather hose" for the power steering pump. I'm now thinking that this is the answer.
