Changing The Engine Coolant - Hyundai Elantra 2019 Owner's Manual

Maintenance
Recommended engine coolant
• When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an phosphate based
ethylene-glycol coolant to prevent
corrosion and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified 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.

Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.

Changing the engine coolant

We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.

cause loss of vehicle control or
damage to paint and body trim.
