Changing The Coolant - Hyundai ix35 2015 Owner's Manual

Maintenance
Recommended engine coolant
• 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.
• The engine in your vehicle has alumini-
um engine parts and must be protected
by an ethylene-glycol-based coolant to
prevent corrosion and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.

Changing the coolant

We recommend that the coolant be
replaced by a HYUNDAI authorised
repairer.
CAUTION
Put a thick cloth or fabric around
the radiator cap before refilling the
coolant in order to prevent the
coolant from
engine parts such as generator.
