This guide will walk you through how to use a fluid color chart to identify leaks in your car, helping you address potential issues before they become serious problems. Learn to recognize engine oil, coolant, brake fluid, and more to keep your vehicle safe Perhaps you’re unsure where to start checking for a problem, but the color of the fluid can point you in the right direction Whether your car is leaking red fluid, brown oil, or another substance, this guide can help you determine from which system the leak may be originating. Fortunately, most car fluid colors vary, and you can usually tell just by the color If the puddle is bright green, orange, or pink, then it’s probably coolant (also known as antifreeze)
Antifreeze is highly toxic, so keep animals and small children away from the puddle. If you’ve got green, teal, orange, or pink fluid leaking under your car near the firewall, then the most likely fault is a leak in the heater core or one of the lines connecting to it.
