2015 FIAT 500L coolant temperature

•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:
•Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer.
•Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze) and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

WARNING!
•Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to cool
an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine off and cold, the level of the
engine coolant (antifreeze) in the bottle should be be-
tween the “MIN” and “MAX” marks.
As long as the engine operating temperature is satisfac-
tory, the coolant bottle need only be checked once a
month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
