I recently bought a 2004 left over mustang for my 79 year old Mother (She
chose whatever car she wanted) She is having a bit of difficulty seeing the
speedometer in bright sunshine and wanted the white face gauges like in my
Thunderbird. No problem, Ford sells the part, yea its expensive, but mom
will only be driving one or two years, and I ride with her every few weeks
to check her driving. go to my friendly Ford dealer ready to plop down over
$300, and guess what I'm told? Changing from black face gauges to white
face gauges is a modification and could void the warrantee. It's only a
inert inactive piece of plastic white vs. black. I was told that upgrading
my wife's mustang from 16 in wheels to 17 in would also void the warrantee
even if I bought the Bullett wheels from Ford, and used the same size tires
as on the GT. Called Customer Service at Ford, guess what? It's true. Ain't
this a great country or what.....
Hmmmm. My dealer says if they install then it's covered. Don't know if
that's because of the dealer, or if it applies across the board. And
they said I could bring the parts from anyplace I could get them

As far as I know only if the modifications are related to the repair needed.
If you put 20" rims on your car your wheel bearings wont be covered if they
take a dump, but your shorted out door lock actuator would still be covered.
It would seem to me that the biggest problem caused by
changing the speedomter is the loss of the correct odometer
reading. I'd say if the dealer does the switch, there should
be no problem. If you do the switch, well, then Ford could
always claim you did the switch to disquise the actual
mileage in an attempt to "extend" your warranty. I suggest
that you buy one of the aftermarket white face gague decal
kits. It will be cheaper and not affect the odometer's
Making unapproved modifications to a vehcile can affect your
warranty. However, it can only affect the warranty on parts
related to the modification. For instance, replacing the
factory radio with a Boom-Master 3000 watt stero might void
the warranty on the factory speakers, it will not void the
warranty on the transmission. However, in your case, the
proposed modification affects everything since it can
potentially obliterate the correct mileage recorded by the
A local farmer got clever and pulled the electrical
connector to the speedometer on his truck. He though this
would allow him to pile up the miles, without having them
show. About the same time he started having transmission
shifting problems. What he didn't understand was that this
was related to unplugging the speedometer. What was worse,
when he took it back to complain, he didn't plug the
speedomter back in. The mechanic figured out the problem was
caused by the unplugged speedomter, pluged it in, and noted
the problem in the computer. Chrysler then told the truck
owner his warranty was void becasue of odometer tampering.
Eventually the dealer got this recinded (claimed it was a
failure, not deliberate) but the guy was sweating for a
while. Moral of the story, don't mess with the odometer.

If the only thing you are replacing is the guage overlay,

original at the time of the replacement, thereby, providing
the correct mileage as required.
The Magnesun-Moss law provides that warranty coverage cannot
be denied to components unrelated to the modification. That
would include the wheels and tires as long as they are
provided as an option on otherwise similar vehicles. Me
thinks your dealer is overly protective of his rear. BTW,
dealers around here make some big bucks doing these kinds of
mods. The ones the Ford dealer won't do, a rice popper
When I bought my 03 Grand Marquis the first thing I did was yank out the wimpy
single exhuast and install a dual flowmaster system. My dealer actually did it
for me, they were cheaper than the Speedy Muffler shop right next door. They
used the Flowmasters that I bought and used the pipes from a wrecked Maureder.
It was a great deal.
If there is a problem that is caused by installing the $300 peice of
plastic, then your warranty for that particular damage would not be valid.
If you engine blows out, the warrenty will still be valid.
Likewise, for problems caused by installing the wheels, the warranty would
be not be valid. But if if the problems are not caused by installing the
wheels, the warranty would still be valid. Besides, if there is a problem,
just put the old wheels back on.
