If the engine coolant has not been
checked at the recommended
interval, the engine coolant
reservoir may become low or empty.
If the reservoir is low or empty, add
engine coolant to the reservoir.
Refer to Adding engine coolant in
this chapter.
Note: Automotive fluids are not
interchangeable; do not use engine
coolant, antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it
is a 50/50 mixture of engine coolant
and distilled water. Add the mixture
to the coolant reservoir, when the
engine is cool, until the appropriate
fill level is obtained.
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,
you can be burned if you spill
coolant on hot engine parts.
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.
