At first, I had an oil leak. Then, as I fixed it by oil change and tightened the oil cap with proper torque, I'd noticed a red fluid underneath where the oil leak trickled. Traced it to the power steering reservoir hoses. I clean those areas so that I can pinpoint which of the three parts went bad. However, I did replaced all three parts since the parts are cheap online. I had to take the plastic cover underneath to be able to see and access the bottom of the hoses and clamps. Ensure you have all the parts available and be ready for hard to get bolts and clamps. Don't forget a small empty milk jug to drain some of the fluids.
This is a PIA for the hoses to the rack. You have little room and need to loosen engine mount and Jack it up to get hands in there. Prepare for skin loss and scratches. hard to get to bolt on cover with shroud in place.
Lost a lot of fluid when car would sit. Leaks found around compression connection of metal and rubber joints. You could spin the metal tubing around like a swivel and it was leaking overnight.
