Your vehicle is very sophisticated and builtwith multiple, complex, performance systems.Every manufacturer develops these systemsusing different specifications andperformance features. That is why it isimportant to rely upon your dealership toproperly diagnose and repair your vehicle.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normaloperating characteristic and, by itself, doesnot necessarily indicate a concern or that thefluid needs to be changed. However, aqualified expert, such as the factory-trainedtechnicians at your dealership, shouldinspect discolored fluids that also show signsof overheating or foreign materialcontamination immediately.
Make sure to change your vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is a viableway to change fluid for many vehiclesub-systems during scheduled maintenance.It is critical that systems are flushed only withnew fluid that is the same as that requiredto fill and operate the system or using aFord-approved flushing chemical.
