Motor vehicle manufacturers
produce Original Equipment Manufactured (OEM) or genuine replacement
parts whilst third party vendors manufacture what’s often
called aftermarket parts.
Motor vehicle manufacturers make huge investments
into the research and development of genuine OEM replacement parts
which is to ensure each part is manufactured identically with
optimum performance in safety and reliability. Genuine replacement
parts are subject to safety recalls and a lifetime guarantee.
Aftermarket manufactured parts particularly
the Asian imported variety have never been crash tested nor are
there any provisions for recalls based on safety or performance.
There are many scientific reports and writings purporting aftermarket
parts adversely affect the performance and safety of a motor vehicle
and your new car warranty.
WARNING: Do not fit aftermarket
or Asian imported replacement parts onto your vehicle. The motor
vehicle manufacturer’s warranty does not cover breakdown
or damage to other vehicle or engine components which result from
the failure of non-genuine fitted replacement parts.
Vehicle manufacturers ensure all genuine OEM
replacement parts produced are tested to perform identically as
original parts as found in new vehicles. Genuine OEM replacement
parts help the vehicle maintain its safe crashworthy integrity
and protect the value of a vehicle longer than if aftermarket
replacement parts are fitted. Vehicles have been known to sustain
large losses in value using aftermarket parts: this is known as
‘Diminished Value’.
Aftermarket parts are sold at greatly reduced
prices because their manufacturer does not bear any cost of research,
development or advertising. Although aftermarket parts look very
similar to OEM replacement parts, there is however much disparity
between them.
Non genuine replacement parts have a high
likelihood of being a serious safety threat. Much of the products
sold as aftermarket parts are manufactured in Taiwan. They are
locally known as ‘Taiwan Trash’ and for good reason;
they have a substandard fit, have an extremely low crash resistance
and mechanical reliability.

The following are very simple
examples of how safety and reliability are superior in genuine
replacement parts against non-genuine parts.
Safety – A motor vehicle body shell
is essentially the ‘backbone’ structure of a motor
vehicle. Body shells undergo rigorous crash testing and engineered
with such precision that when all support members and components
are welded together, they create a structural integrity of zero
tolerance.
Zero tolerance integrity provides the perfect
platform from which the remainder of the car can then be assembled
to deliver an optimum level of safety giving occupants the best
possible chances to survive if involved in a motor vehicle collision.
If the notion is accepted that the preservation
of life is paramount and is why vehicle manufacturers go to great
lengths to ensure their product accommodates for this, then the
question needs to be asked why are collision damaged vehicles
not repaired to similar standards? The bottom line is simply all
about repairing the vehicle at the least possible price and not
much else.
For example, instead of replacing damaged
body shell components at the manufactured seams and joints, turrets,
centre pillars and other structurally important body shell components
are being indiscriminately cut in areas where safety is dangerously
compromised and the incised area later disguised with ‘bog
and shinny new paint’.
It is far quicker and therefore cheaper for
smash repairers to adopt this method of repair than to follow
the correct repair protocols and replace the damaged area with
new OEM components pursuant to the manufacturers recommended
specifications.
Despite the fact that the motor vehicle manufacturing
industry goes to great pains and huge expense to design, test
and build safe crashworthy motor vehicles, their results are unfortunately
being completely destroyed by smash repairers (and other stakeholders)
involved in the smash repair industry only to bolster their own
bottom line.
As described in ‘The truth about the
smash repair industry’ link on this site, whilst smash repairers
continue to disregard the recommended smash repair guidelines,
motor vehicle structural integrity will continue to be compromised
and the personal safety of vehicle occupants will continue to
be put into grave danger.
Reliability – Genuine radiators are manufactured
from aluminium. The metal properties of Aluminium repel heat.
Genuine radiators are factory guaranteed and designed to hold
specific quantities of water through a series of internal cores
specific to the vehicle they are fitted. This ensures for maximum
cooling efficiency and protects the engine and its components.
Aftermarket radiators are generally made from
Copper which attract or conduct heat. They are painted to resemble
the original genuine replacement part yet they hold less quantities
of water and have less core structures which greatly compromise
engine efficiency and cooling.
Aftermarket radiators cause engines to run
at hotter temperatures which are likely to cause overheating and
head gasket failure. It is almost impossible to trace the source
of a head gasket problem when radiator pressure tests do not register
any apparent faults. Under these circumstances it would be impossible
to determine that gasket failure was caused by an aftermarket
fitted radiator consequently leaving the vehicle owner liable
for the cost of all mechanical repairs.
If a aftermarket radiator is fitted
it is likely the engine will continue to run at hotter temperatures
and the head gasket will again breach with a high probability
of damaging other engine components. The manufacturers warranty
will not cover the cost of such repairs because the initial damage
was caused by a non genuine part.
