2012 Acura RDX coolant temperature

SH-AWD Torque Distribution
MonitorOn SH-AWD modelsThis monitor shows how much
torque is being delivered to each
wheel. For more information, see
page 384.
Tire Pressure Monitor
You can see the pressure of each tire
in this monitor. If one or more tire
pressure are low, inflate them to the
correct pressure. For more
information, see page 392.Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the reading should rise
from the
‘‘C (Cold)’’ mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may rise to near
the ‘‘H (Hot) ’’mark of the gauge. If it
reaches the ‘‘H ’’mark, pull safely to
the side of the road. See page 463 for
instructions and precautions on
checking the engine's coolant
system.

●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
ᤳ 2fluid
Driving in mountainous areas at very low vehicle speeds
or trailer towing results in higher transmission and
transfer temperatures. This requires transmission and
transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed at 60,000
miles (100,000 km), then every 30,000 miles (48,000 km).

●Replace spark plugs●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid
ᤳ 2
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).

The reading of the vehicle's
temperature gauge on the multi-
information display should stay in the
midrange. If it climbs to the H (Hot)
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on the
display and blink for several times.
At the same time, the beeper will
sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming from under the hood.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road. Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights. 2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.
4. If the temperature gauge reading stays at the H (Hot) mark, turn off
the engine.

5. Look for any obvious coolantleaks, 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 (see Emergency
Towing on page 475).
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 reading
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
temperature to maximum heat
(climate control to AUTO at
‘‘
’’). 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 watch
the temperature gauge. If it goes
back to the H mark, the engine
needs repair (see Emergency
Towing on page 475).
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.
