Clear Water Leak from Subaru Outback (AC Off)
Clear water leaking under the vehicle when the AC was not running is likely condensation from the air conditioning system or normal water drainage. Since the AC was off, it may be residual condensation or another source like windshield washer fluid or coolant (if clear and odorless). However, coolant is usually colored and sweet-smelling, so this is less likely. The most common cause is AC condensation draining after use, which can continue for a short time after the AC is turned off.

What You Should Do
Check the fluid color, smell, and location.
If it's clear and odorless, it's likely normal condensation.
If it's slightly blue or has a soapy feel, it's washer fluid.
If it's colored (green, pink, orange) or sweet-smelling, it's coolant.
Monitor the fluid level in the coolant reservoir and check for leaks around the windshield washer system.
If the leak persists or you notice other symptoms, have the vehicle inspected.
