Checking Oil Level; Cooling System - Jeep Renegade 2018 User Manual

Checking Oil Level

To assure proper engine lubrication, the en-
gine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such as every fuel stop. The best time to
check the engine oil level is approximately
five minutes after a fully warmed engine is
shut off. Do not check oil level before starting
the engine after it has sat overnight. Check-
ing engine oil level when the engine is cold
will give you an incorrect reading.
Checking the oil while the vehicle is on level
ground, and approximately five minutes after
a fully warmed engine is shut off, will improve
the accuracy of the oil level readings. Main-
tain the oil level between the range markings
on the dipstick. The safe range is indicated
by a crosshatch zone. Adding 1 quart (0.9 Li-
ters) of oil when the reading is at the low end
of the indicated range will result in the oil
level at the full end of the indicator range.
CAUTION!
Do not overfill the engine with oil. Overfill-
ing the engine with oil will cause oil aera-
tion, which can lead to loss of oil pressure
and an increase in oil temperature. This
loss of oil pressure and increased oil tem-
perature could damage your engine.

Cooling System

WARNING!
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
WARNING!
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed
and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
