CATCH IT BEFORE IT COSTS YOU: LEAK DETECTION SERVICES AT AUTO SELECT

Noticing a puddle under your car used to be a clear warning sign that something was wrong. But today, many newer vehicles are designed with drip trays and underbody covers that catch or deflect small leaks before they ever hit your driveway or garage floor. That means the warning signs of a fluid leak can go unnoticed—until it turns into a bigger, more expensive issue. At Auto Select, we offer professional leak detection services to help spot problems early, even the ones your garage floor won’t show you.


Common Types of Vehicle Leaks to Watch For Your vehicle relies on a variety of fluids to keep it running smoothly. Each has a different job—and a different warning sign if it starts to leak: 


  • Engine Oil – Typically brown or black, oil leaks can come from gaskets, seals, or the oil pan. Left unchecked, it can lead to engine damage. 
  • Coolant/Antifreeze – Often green, orange, or pink, coolant leaks can come from the radiator, water pump, or hoses. Loss of coolant can cause engine overheating. 
  • Transmission Fluid – Usually red or reddish-brown, this slippery fluid helps keep your transmission running smoothly. Leaks can be costly if not addressed. 
  • Brake Fluid – Light yellow to brown, brake fluid leaks are a serious safety concern. If your brake pedal feels soft, get it checked immediately. 
  • Power Steering Fluid – Similar in color to transmission fluid, a leak can cause difficulty steering. 
  • Windshield Washer Fluid – Often bright blue, this one’s not dangerous, but it’s good to know you have washer fluid when you need it!.  Fuel Leaks – Whether it’s gasoline or diesel, you’ll usually smell this one before you see it. Fuel leaks are dangerous and should be addressed immediately.


Drip Trays: Helpful but Hiding While underbody drip trays help keep your garage floor clean, they can also mask leaks from view. That’s why routine inspections are more important than ever. Our trained technicians at Auto Select can inspect your vehicle’s undercarriage and fluid systems to identify potential leaks early—before they become a safety hazard or lead to costly repairs.


3-Day Leak Detection using Dye & UV Lights If you really want to make sure your vehicles have no leaks, Auto Select can add a special UV dye to your vehicle’s fluid systems, then have you drive as usual for a few days. When you bring the vehicle back in, our technicians use UV lights and inspection tools to track exactly where the leak is coming from. It’s fast, non-invasive, and extremely accurate—and best of all, there’s no cost to you.
