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, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your authorized servicing dealership. Your vehicle’s oils and fluids
should be changed 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.
OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to ensure proper retention.
