Fluid Leak Diagnostic

Leaks traced to their source and identified by fluid type.

Signs you need this

  • Puddle or spots where you park
  • A burning smell after driving
  • A fluid level dropping between services
  • Smoke or steam from under the hood

The colour and location of a drip tells you a lot: oil, coolant, transmission fluid, brake fluid, and power steering fluid all leak differently and carry very different levels of urgency. A brake fluid leak is a stop-driving problem. A minor oil seep may be something to monitor.

We clean the area, use dye where needed, and find the actual source rather than the lowest point it happens to drip from — those are often far apart.

Common questions

How do I tell what's leaking from the colour?

As a rough guide: clear and watery is usually just A/C condensation and harmless, amber to black is engine oil, red or pink is transmission fluid or power steering, green or orange is coolant, and clear-to-slippery at a wheel is brake fluid. We identify it properly rather than guessing from the driveway.

Is it safe to drive with a leak?

It depends entirely on what and how fast. A brake fluid leak means don't drive it. A weeping valve cover gasket can wait. That's the first thing we tell you — an honest read on urgency, before anything else.

How do you find a leak you can't see?

UV dye tracing, pressure testing the cooling system, and time on the hoist with the underbody cleaned first. Leaks travel with airflow, so where the drip lands is rarely where it started.
