ENGINE COOLANT CHECK -

WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you.
Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly.
Do not add coolant further than the
MAX
mark.
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Note:
Make sure that the coolant level is
between the
MIN
and
MAX
marks on the
coolant reservoir.
Note:
Coolant expands when it is hot. The
level may extend beyond the
MAX
mark.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C).
Note:
For best results, coolant
concentration should be tested with a
refractometer such as Robinair® Coolant
and Battery Refractometer 75240. We do
not recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note:
Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant
Note:
Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the engine cooling or
heating systems. This damage would not
be covered under your vehicle’s warranty.
