Fluid Leak Diagnosis at our Sebring shop

Color and location are a starting point, not an answer. Dark brown or black is usually engine oil. Bright green, orange, or pink with a sweet smell is coolant. Red or reddish brown and slippery is transmission fluid. Clear to amber, oily between your fingers, and near a wheel or the firewall points at brake fluid. Plain water dripping from the middle of the car on a hot afternoon is almost always AC condensate, which means the system is working the way it should and there is nothing to fix.

That narrows things down. It rarely tells us where the leak actually is. Fluids don't fall straight down. They run along the block, follow a seam in the pan, ride a wiring harness or a frame rail, and drip off the lowest point they reach, which can be a foot or more from where they got out. Airflow at highway speed carries them further back. The spot on your driveway is where the fluid finished, not where it started.

So we go find the start. First we clean the area, because old residue and road grime hide a fresh leak and make a small seep look like a catastrophe. Then, where it helps, we add a UV dye to the system in question and run the car the way you actually drive it. Under a black light, the dye traces back to the exact gasket, seal, line, or fitting the fluid is leaving from. On a leak that only shows up warm or under pressure, that is the difference between an answer and a guess.

You get photos of the source itself on your phone, plus an honest read on how urgent it is. Not everything that leaves a mark needs fixing today. A light seep at a valve cover that hasn't moved the oil level in months is a watch item, and we'll tell you that. A wet brake line is a different conversation, and we'll tell you that too.
