Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the
fluid needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified intervals
or in conjunction with a repair. Flushing is a viable way to change fluid for
many vehicle sub-systems during scheduled maintenance. It is critical that
systems are flushed only with new fluid that is the same as that required to
fill and operate the system or using a Ford-approved flushing chemical.
