2012 Acura MDX engine coolant

1. Make sure the engine and radiator
are cool.
2. Remove the radiator cap cover.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.
3. Remove the radiator cap by
pushing down and turning
counterclockwise.4. The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.
Pour the coolant slowly and
carefully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
5. Put the radiator cap back on, and
tighten it fully.

6. Pour coolant into the reserve tank.
Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or
engine components.Windshield Washers
Check the fluid level in the
windshield washer reservoir at least
monthly during normal use.
If the washer fluid is low, a‘‘LOW
WASHER FLUID’’message appears
on the multi-information display.
Fill the reservoir with a good-quality
windshield washer fluid. This
increases the cleaning capability and
prevents freezing in cold weather.
When you refill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer fluid
on a clean cloth. This will help to
condition the blade edges.
Do not use engine antifreeze or a
vinegar/water solution in the
windshield washer reservoir. Antifreeze
can damage your vehicle's paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer fluid.

Unclip hose from the stay brackets
on the engine coolant reserve
tank.
3. Remove the electrical connector
from the bulb by pushing on the
tab and pulling the connector
down.

4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Look for any obvious coolant
leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (seeEmergency
Towingon page 572).
6. If you do not find an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.9. Start the engine and set the
climate control to AUTO at‘‘Hi.’’
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeEmergency
Towingon page 572).
11. If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.
