Leaks can quickly turn expensive if not repaired immediately. Gaskets are cheap and can usually be replaced for under $5. Some leaks may come from a loose part or filter that only needs to be tightened. Taking the time for proper repairs and maintenance will add years to the life of your vehicle and will help protect our streams for future generations.

Tips for finding the source of vehicle leaks
Vehicle leaks can be elusive as there are a number of fluids in your vehicle and they can come from a variety of areas. Matching the color, odor, consistency, and location of the leak will give you a very good indication of its source. Here are some tips from the experts to help you in your search:
Get a piece of white cardboard or use a white paper towel over cardboard and place it under your vehicle where you see the fluid stains or suspect a leak (a 2' x 4' section works best).
Let the cardboard sit for several hours or overnight.
Check to find exactly where the oil is coming from (could be engine, sump, filter, driveshafts or gearbox) and try to trace all leaks to their source (often oil will pool in one area but will originate from above). Clear away any dirt and grime to determine the actual leak. Most leaks come from failed plugs, seals, or gaskets.
