Engine Compartment Check Locations; Engine Cooling System - Renault ALASKAN 2017 Driver's Handbook Manual

•
Your vehicle is fitted with an automatic en-
gine cooling fan. It may come on at any time
without warning, even if the ignition switch is
in the OFF position and the engine is not run-
ning. To avoid injury, always disconnect the
negative battery cable before working near
the fan.
•
Always wear eye protection whenever you
work on your vehicle.
•
Never leave the engine or the transmission
related component harness
disconnected while the ignition switch is in
the ON position.
•
Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil, en-
gine coolant, and/or other vehicle fluids can
hurt the environment. Always conform to lo-
cal regulations for disposal of vehicle fluids.
This "8. Maintenance and do-it-yourself" section
provides instructions regarding only those items
which are relatively easy for an owner to perform.
You should be aware that incomplete or improper
servicing may result in operating difficulties or ex-
cessive emissions, and could affect your warranty
coverage. If in doubt about any servicing, have it
done by an approved dealer or qualified work-
shop.

ENGINE COOLING SYSTEM

WARNING
•
Never remove the radiator or coolant reser-
voir cap when the engine is hot. Serious burns
could be caused by high-pressure fluid es-
caping from the radiator. Wait until the engine
and radiator cool down.
•
Engine coolant is poisonous and should be
stored carefully in marked containers out of
the reach of children.
The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and
corrosion inhibitors, therefore additional cooling sys-
tem additives are not necessary.
CAUTION
•
Never use any cooling system additives such
as radiator sealer. Additives may clog the
cooling system and cause damage to the en-
gine, transmission and/or cooling system.
•
When adding or replacing coolant, be sure to
use the proper mixture ratio. Examples of the
mixture ratio of coolant and water are shown
in the following table:
