I have noticed a very slight leak(s) on the underside of the car. Iwas wondering if anyone knows where they might be coming from?

i have noticed a small (almost trace) amount of coolant on the the black sheet metal under the power steering rack on this picture, i have since wiped it off but it seems to be collecting on the right side. It doesn't appear to be power steering fluid.

I have also noticed what seems to be a leak coming from where a line connects to the power steering rack, and i noticed the line (some what hidden by the sway bar) that runs from the PS reservoir to the rack has some fliud on it. I couldn't tell where it was coming from, maybe dripping from the reservoir onto the line?

One more thing i noted was the seepage from the pinion seal. I know this is common but does seem like an excessive amount?
All these leaks are very minor and none cause any fluid the drip on the ground. I also peridocially check the fluids are they are never low by a considerable amount.
Thanks

 

The best way to pinpoint a leak is to thoroughly clean the area and re-observe.
