CATALYTIC CONVERTOR

Damage to the catalyst will result if
contamination occurs through the use
of leaded fuel. Whilst the vehicle is
fitted with a reduced diameter filler
neck to prevent charging of the fuel
tank with a leaded fuel pump nozzle,
it is possible that the use of funnels or
jerry cans will permit leaded fuel to be
introduced into the fuel tank.
The catalyst is intolerant of unburnt
fuel and therefore if an engine misfire
condition exists, damage to the cata-
lyst will occur. It is imperative that if
a misfire condition develops, the ve-
hicle is immediately presented to a
Hyundai dealer for rectification. Simi-
larly, the practice of certain ignition
system diagnosis procedures which
involve inducing a misfire (cylinder
power balance tests for example) may
result in catalyst damage.
For these reasons, it is advisable that
the exhaust gas emission be tested
at each routine service with a gas
analyzer having a Hydrocarbon mea-
suring facility to ensure continued re-
liability of the catalyst.
Push or tow starting of the vehicle is
to be avoided since unburnt fuel may
be enter the catalyst and result in
damage.
(Note, it is impossible to
push or tow start a Hyundai model
equipped with fuel injection since the
fuel pump safety interlock will prevent
the pump from operating under these
conditions).
Operation of the catalyst involves
extremely high temperatures being
attained within the catalytic conver-
tor, and although the convertor is
fitted with heat shields, it is important
that the vehicle is not parked over
combustible or volatile material which
may result in fire.
If the above precautions are not ad-
hered to and the catalyst becomes
inoperative, the resultant increase in
core temperature will result in a "melt
down" where the catalyst core will
melt and subsequently may block the
exhaust system.
Due to the fragile nature of the cata-
lyst element, it is important that dam-
age does not occur when the vehicle
is raised by means of a garage jack.
Care must also be exercised to avoid
driving over road hazards or debris
which may cause damage to the cata-
lyst element.
Catalytic Converter
HGK5061
Hyundai Coupe models are fitted with
catalytic convertors which require
special operating considerations. The
catalytic convertor serves to oxidize
certain noxious elements of the ex-
haust gases leaving the engine to
reduce the level of pollutants emitted
from the vehicle and, provided that
care is exercised to prevent damage,
the catalyst will operate efficiently for
the life of the vehicle.
It is of the utmost importance that the
following information is read and un-
derstood by the vehicle operator in
order to prevent operational problems
arising from damage to the catalyst.
