I was snowblowing my driveway today, when I noticed some tracks of yellow liquid on the driveway. It was underneith my car and my mom's car. I was beginning to think antifreeze, although it green. I can't think of any other fluid that could remotely close to yellow comming from a car. And I don't have any animals (thinking it was animal piss). Checked fluids on both cars and they were fine. Could I be imaging this yellow fluid?

Brake fluid? Badly worn out power steering fluid?

You're car is bleeding the lizzard.

Antifreeze does look yellow on snow. Most of the green is a surface effect of additives, since ethylene glycol is basically clear.

I've seen the same thing w/ both of my Jeeps. At first I thought I also had a fluid leak. Took it to the dealer and they couldn't find anything. I never see any wet spots when I park my Jeep on dry groung (my garage), so I've convinced my self that it is not a fluid issue. I've noticed this yellow fluid dripping off of my exhaust when I do an undercarriage spray clean. I've attributed it to some sort of rust issue.

When it gets really cold, the radiator inlet & outlet pipes contract and coolant will leak. The leak disapears when the radiator warms and expands. I usually see it when the my truck sits outside when it get -10 or colder.

power steering fluid is usually black-ish when old, maybe brown (usually red originally, add carbon and, yuck).

mighta been a kid hatin on your car and took a leak on it

mechanic put it on a lift and didn't find any leaks. Wondering if it's my moms taurus.

An animal or something pissed in the driveway?
