Fluid leaks in Dodge trucks are common, but not insignificant. Leaks should be diagnosed and repaired quickly. Usually, the problem is caused by a loose hose or a crack in the fluid container. Fluids are vital to keep an engine lubricated and operating properly. The type of leak can be diagnosed by the color of the fluid. A simple test will show which fluid you need to examine more closely for repair.
Place the sheet of cardboard underneath the engine compartment of the truck. Leave the cardboard under the truck overnight and pull it out to examine it in the morning.
Check the oil levels in your truck by removing the dipstick from the oil container if your fluids are light or dark brown. Change your oil if the liquid is dark brown, and ask your truck's technician to check the oil filter and the oil container.
Check the transmission fluid if the leak is pink or red in color by taking out the dipstick from the transmission. If fluid levels look normal, take the truck to a certified mechanic to examine any holes or cracks in the hoses or the container.
Look at the master brake cylinder (usually located in the top-right corner of the engine compartment) to see fluid levels if the leak is light yellow or muddy brown in color. Look at the container for cracks. Take the truck to a mechanic if any serious cracks have occurred or if the leak grows larger every day.
Ask a mechanic or knowledgeable friend to examine the rear axle or the transmission (if manual) for the leak source if the fluid is light brown with a rotten-egg odor.
Check the labeled, clear containers of washer fluid, coolant or power steering fluid in the engine to determine levels of fluid if the leak is bright green, blue, orange, pink, yellow or clear in color. Check for cracks in the plastic.
Look at the gas tank underneath the tank opening for cracks if the liquid is amber and smells like gas. Take the truck immediately to a mechanic for repair, as gas leaks can be fatal.
