Performing a simple leak test on your vehicle is an easy way to catch potential problems before they become costly repairs. Start by parking your car on a clean, flat surface like a driveway or garage floor and allow it to remain stationary for several hours or through the night so any leaks have time to show up. In the morning, look under the car for any puddles or stains.

You may notice clear moisture from the AC drain, a typical and اتوسرویس داوود harmless occurrence or vibrant fluids including crimson or amber-colored transmission fluid. Green or orange coolant or dark oil.

Next, check the engine compartment. Unlatch the hood and scrutinize the engine casing, coolant radiator, rubber hoses, and oil reservoir base. Look for wet spots, drips, or residue that might indicate a leak. Note the hue and texture of the substance you observe. Motor oil is heavy, sticky, and usually black or dark brown. Coolant is often bright in color and slightly sticky. Brake fluid appears transparent or pale amber and feels slick to the touch.

Check your fluid levels using the dipsticks and reservoirs under the hood. Should your motor oil, radiator fluid, or brake fluid be below full despite recent refills that’s a clear indicator of fluid loss. Recheck the pavement under your vehicle after a brief drive. Some leaks activate only after the engine heats up and builds pressure.

When the leak is elusive or faint, you can use a simple trick with baby powder or flour. Lightly sprinkle it around suspected areas like the oil pan, transmission, or radiator connections. Once you’ve driven the vehicle for 10–15 minutes come back and inspect for displaced powder or colored marks. This can help you pinpoint the exact source.

If you find a leak, don’t ignore it. Even small drips can lead to serious damage over time. For minor leaks, you might be able to tighten a loose hose clamp or replace a worn gasket. But if you’re unsure or the leak seems significant it’s recommended to visit a certified technician. Regular leak checks can save you money. Prevent breakdowns. And keep your car running safely for years.
