Would a coolant leak show up as a light brown liquid that eventually dries?

I found a dried and now a wet spot under the car this morning. It's not oil but it's also not pink. When it dries, it looks more yellow than brown. No, I didn't pee under the car. ;-)

Default It was PS/hydraulic fluid when I saw that on my Avant last year. Under front drivers side of car?

Was an easy fix as just one hose & clamp was needing to be replaced and they did it as a bonus when they did the TB, h2o pump, etc.

It was fairly centered left to right, in the front of the vehicle

Also, it didn't have the greasy feel of hydraulic fluid

Default my guess would be that perhaps the radiator is leaking at the lower front seam a bit?

Do you have belly pan on your car?

This actually happened to our sedan last year but I didn't see it until I pulled the belly pan off to do an oil change. That is when I noticed some dried up crusty coolant (both pink and brown looking cause of dirt I think) on the belly pan and we ended up replacing the radiator before it got any worse. HTH...

Default It can.. it feels very oily too. Check for pink crusties. Also, smell the liquid...

Coolant has a very distinctive smell.

I would not pass up checking for leaks at the axles though.

You didn't mention which transmission you have on your car,.

Default Yeah, I'd double check everything under there.. I had a leaking driver's side axle seal..

Turns out, the driver's side axle on a tip box seals in trans fluid. If it's that, I'd get it checked ASAP.

I think I found the problem! I think the battery is in bad shape. It might be leaking fluid.
