Recommended Engine Coolant - Hyundai 2009 Elantra Owner's Manual

Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
Hyundai dealer for a cooling system
inspection.

Recommended engine coolant

• Use only soft (de-mineralized) water in
the coolant mixture.
• 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.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
OHD076008
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
