Source of oil / power steering fluid leak

2000 V70R. It stays under a car cover in the garage over the winter. I start it every so often during the winter months. I moved it out of the garage over the weekend only to find a good sized (5 inch) oil puddle under it. I assumed it was oil as it was clear and I had just changed the oil before storing the car for the winter.

Anyway, after much hunting I just can't find the source of the leak. It seems to be dripping from the bottom of the a/c compressor making me think it's actually power steering fluid from the p/s pump above it. The fluid is so clear - almost too clear to be motor oil.

The p/s pump seems to be dry - just a little damp on the surface of the hose that goes to the reservoir. The line that goes to the rack is dry.

I don't think the turbo return line is in play - as the leak is more to the front of the car. No leak from the base of the dipstick.

Has anyone encountered a leak which appeared to find it's way to the bottom of the a/c compressor before dripping on the ground? I just can't seem to find the source.

Thanks! Steve.

check the hose clamps on the hose that supplies to the pump, they tend to be the culprits

Thanks, I did check that - it was damp but not leaking. This is a significant leak. I did run the car and check the hose to see if it was leaking while running - it stayed dry under the hose, but it was still dripping under the car.

Isn't power steering fluid red, not clear?

The HVAC system holds an oil called ester oil that is added when you top up the r134a- it comes in the can that you use to refill. Compressors like somewhat regular use and the seals may have gone- not unexpected on a car with such low miles in 9 years. Probably ought to check r134a level, if ac is working.

Remember that a 5 in oil spot is just a few drips really.

Make sure it's oil and not antifreeze.
