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
the cap is loosened slightly.
Do not add coolant further than the
MAX mark.
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.
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.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red. As long as the
engine coolant is clear and uncontaminated,
this color change does not indicate the
engine coolant has degraded nor does it
require the engine coolant to be drained,
the system to be flushed, or the engine
coolant to be replaced.
When the engine is cold, check the
concentration and level of the engine coolant
at the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 367).
Note: Make sure that the 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.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See Adding Engine Coolant
in this chapter.
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.
