2011 Acura MDX engine coolant

Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For
instructions and precautions on
checking the engine's cooling
system, see page 554.
Fuel Gauge
This shows how much fuel you have.
It may show slightly more or less
than the actual amount.Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
U.S. model is shown.TEMPERATURE

Oil CheckWait a few minutes after turning the
engine off before you check the oil.1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean cloth or paper towel.
3. Insert the dipstick all the way back into its hole.
4. Remove the dipstick again, andcheck the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see Adding Engine Oil on page 511.Engine Coolant Check
Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
Adding
Engine Coolant on page 514 for
information on adding the proper
coolant.
Refer to Owner's Maintenance
Checks on page 507 for information
about checking other items on your
vehicle.

U.S. Vehicles:
According to state and federal
regulations, failure to perform
maintenance on the items marked
with＃will not void your emissions
warranties. However, Acura
recommends that all maintenance
services be performed in accordance
with the intervals indicated by the
multi-information display. Owner's Maintenance Checks
You should check the following
items at the specified intervals. If you
are unsure of how to perform any
check, turn to the appropriate page
listed.
●
Engine oil level
－Check every
time you fill the fuel tank. See page
422.
●
Engine coolant level －Check the
radiator reserve tank every time
you fill the fuel tank. See page 422.
●
Automatic transmission －Check
the fluid level monthly. See page
517.
●
Brakes －Check the fluid level
monthly. See page 519.
●
Tires －Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page
535.
●
Lights －Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
and license plate lights monthly.
See page 521.

NOTE:
●Independent of the maintenance messages in the multi-
information display, replace the brake fluid every 3 years.●Inspect idle speed every 160,000 miles (256,000 km).●Adjust the valves during services A, B, 1, 2, or 3 if they are
noisy. Symbol Maintenance Sub Items
1
●Rotate tires
2●Replace air cleaner element
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).●Replace dust and pollen filterIf you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from
diesel-powered vehicles, replace every 15,000 miles
(24,000 km).●Inspect drive belt
3●Replace transmission and transfer fluid
4●Replace spark plugs●Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), in very low temperatures (under －20°F, －
29°C), or towing a trailer, replace every 60,000 miles (U.
S.)/100,000 km (Canada).●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000
km), then every 15,000 miles (24,000 km).

Adding Engine CoolantIf the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX
line. Inspect the cooling system for
leaks.Always use Honda Long-life Anti-
freeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antifreeze and 50 percent water.
Never add straight antifreeze or plain
water.
If Honda antifreeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it
is a high-quality coolant
recommended for aluminum
engines. Continued use of any non-
Honda coolant can result in
corrosion, causing the cooling
system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/
coolant as soon as possible.If the reserve tank is completely
empty, you should also check the
coolant level in 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.
