Pinpoint Leaks Fast with a Subaru Dye Test at Capitol Subaru in Salem

April 15th, 2025

Your Subaru engine and mechanical systems rely on precision, pressure, and clean fluid pathways to function properly. But when a leak develops-whether from the engine, transmission, brake lines, or cooling system-it can quietly snowball into serious, expensive damage. At Capitol Subaru in Salem, OR, our expert technicians use advanced leak dye testing to locate hidden leaks early-before they turn into major problems. It's not always easy to tell where a leak is coming from. You might notice small puddles beneath your vehicle, burnt smells after a drive, or even dashboard warning lights. But identifying the exact source often requires a deeper look. That's where our fluorescent dye testing comes in. By using Subaru-approved dyes and UV lights, we can safely trace the fluid path and reveal the leak's origin-whether it's a worn gasket, loose hose, or cracked component. It's fast, effective, and saves you from the stress of guesswork and unnecessary repairs.

How a Subaru Dye Test Works

So, what exactly happens during a dye test? Our technicians add a Subaru-specific fluorescent dye to the suspected fluid system-engine oil, coolant, transmission fluid, power steering fluid, or brake fluid, depending on the symptoms. Once circulated through the system, the vehicle is inspected under UV lighting. The dye glows brightly at the point of the leak, allowing us to detect even the smallest cracks or seepage. This process is particularly useful when the source of a leak isn't immediately obvious. Sometimes fluid will travel along engine components or hoses, making it look like the leak is in one place when it's actually starting somewhere else. Dye testing eliminates that confusion. It gives our Subaru-certified team a clear visual cue and a path forward-so they can recommend the proper fix right away. Whether the leak is minor or significant, catching it early prevents cascading issues like overheating, oil starvation, or loss of brake pressure. And because the dye test is non-invasive and safe for your vehicle, it's a reliable diagnostic method we use with confidence.
