When stopping for gas on the way home, I noticed a red fluid running out from the front of my car. It had a reddish tint to it and was coming out from under the passenger side wheel. I checked the anti-freeze resevoir while at the gas station and it was completely full.
I drove my car home (less then a mile), and left it running while I got out and looked under the car; there was no drip. However after idling for a few minutes it had a steady drip of fluid.
Checking the resevoir again, it was still at the fill line.
Is it a anti-freeze leak, or could it be something else? How do I determine the origin?
EDIT
It's definitely an anti-freeze leak, I just went out and checked and the resevoir was entirely empty.
So 2 questions: 1. What could cause that? 2. Can I fill it and drive it to a mechanic in the morning and be ok?
