Finding the Leak
- Identify the fluid. Determine whether it is engine oil, automatic transmission fluid, power steering fluid, etc.
- Identify where the fluid is leaking from.
- After running the vehicle at normal operating temperature, park the vehicle over a large sheet of paper.
- Wait a few minutes.
- You should be able to find the approximate location of the leak by the drippings on the paper.
- Visually check around the suspected component. Check around all the gasket mating surfaces for leaks. A mirror is useful for finding leaks in areas that are hard to reach.
- If the leak still cannot be found, it may be necessary to clean the suspected area with a degreaser, steam, or spray solvent.
- Clean the area well.
- Dry the area.
- Operate the vehicle for several miles at normal operating temperature and varying speeds.
- After operating the vehicle, visually check the suspected component.
- If the leak is not located, try using the powder or black light and dye method.
