Default Power Steering Leak?

Looking for thoughts on the source of a leak that sprung out of my 2001 986S recently (pics below).

For the past 6 years the Boxster has been stored winters offsite (~Nov to March), but we moved into a new house over the summer and I now have room to store it in my home garage. As such, I had access to the car during our unusually warm and dry December, so I commuted to work in it for the week prior to Xmas, even getting out for a spin on Christmas Eve. Outside temperatures were in the range of -5C to +5C (25F to 40F).

The last times I had the car out, it leaked fluid afterwards. My best guess is power steering fluid? It's oily with little to no smell. I believe its a clear fluid and is picking up the rust colour from other components after it has leaked. Perhaps from a leaky power steering pump or from the overflow line? From a driving perspective, I didn't observe anything out of the ordinary in terms of steering effort, noise, etc. Thoughts?

This is the 1st time I've driven the car in these temperatures - could that have contributed to the issue or just a coincidence?

That looks more like coolant, PS fluid isn’t quite that fluid. Either way, it’s time to pull the engine covers and see what you’ve got. That’s a pretty significant leak to be leaving trails like that, and given their spacing it looks like the fluid is actually in your under tray and flowing out of the holes.

If it is a PS leak, you should be able to see oil on the top part of the engine, some parts of the structure of the engine makes some "pools", and you should be able to touch and see that.
Sure, other component (oil filter, etc..) could also make leaks in this place.
Open to top engine (roof in "service" position), and take a look at "what's up" down there !

Have to agree with Deof3. That looks more like coolant. Coolant has a slick feel between the fingers but should be water soluble.

Check the power steering and coolant and brake fluid levels.

If that is power steering fluid the level should be down. The power steering system doesn't not hold a lot of fluid so any fluid loss will show up as a low fluid level. If the level is down top it up as a power steering pump does not do well under low fluid level conditions.

Be sure you use the right power steering fluid. I believe -- but you need confirmation -- the fluid is Pentosin. Anyhow, use the right fluid.

While you have the engine cover removed and the engine exposed check for any leak sign.

And that is only half the job. The car needs to be lifted up and a careful/thorough check made for any leak sign from under the car.
