Maintenance
Recommended engine coolant
(Continued)
When adding coolant,  use only deion-
ized water or soft water for your vehicle
and   never   mix  hard   water   in   the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
Even if  the engine  is not operat-
ing,  do  not remove  the  radiator
cap  or  the drain  plug  while  the
engine and  radiator  are hot.  Hot
coolant and steam  may still blow
out under pressure, causing seri-
ous injury.
The  engine  in  your  vehicle  has  alu-
minum engine parts  and must be  pro-
tected   by  an   ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
WARNING
The electric motor (cool-
ing fan) is  controlled by
engine coolant tempera-
ture,   refrigerant    pres-
sure and  vehicle speed.
It   may  sometimes   operate   even
when  the  engine   is  not  running.
Use extreme caution when working
near the  blades  of the  cooling fan
so  that  you  are  not  injured  by  a
rotating  fan blades.  As the  engine
coolant temperature decreases, the
electric   motor   will  automatically
shut off.This  is a normal condition.

DO  NOT   USE  alcohol  or   methanol
coolant or mix  them with the specified
coolant.
Check the  condition and  connections of
all  cooling   system   hoses  and   heater
hoses. Replace  any  swollen or  deterio-
rated hoses.
Do  not  use  a  solution  that  contains
more than 60% antifreeze or  less than
35%  antifreeze,  which  would  reduce
The
coolant    level   should    be   filled
between F (MAX) and  L (MIN) marks on
the side of the coolant reservoir when the
engine is cool.
the effectiveness of the solution.
For mixture  percentage, refer  to the  fol-
lowing table.
If  the coolant  level  is  low,  add enough
distilled (deionized) water. Bring the level
to F (MAX), but do not overfill. If frequent
coolant refill  is required,  see an  author-
ized HYUNDAI  dealer for a  cooling sys-
tem inspection.
