sensor CADILLAC ELDORADO 2001 10.G User Guide

3-6 Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located on top of the instrument panel near the
windshield. The ECC panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
Press the AC button or the TEMP/AUTO knob to turn
the system on and then select the proper mode to direct
airflow. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed and
power. This is normal because the system is designed
to cycle the compressor on and off to keep the
desired temperature.

Engine Air Cleaner/Filter
The engine air cleaner/filter is located next to the
windshield washer fluid reservoir on the driver's side of
the engine. For more information on location, see
ªEngine Compartment Overviewº in the Index. Be sure
the engine has cooled before following these steps to
replace the engine air cleaner/filter:
1. With a screwdriver,
loosen the air duct
clamp, which is located
at the mass airflow
sensor end of the
air duct.
2. Disconnect the air duct from the mass airflow sensor.

3. Unhook both engine air cleaner/filter cover latches.
One latch is located near the radiator hose (not shown)
and the other latch is located next to the IAT sensor.
4. Pivot the air cleaner and air duct assembly toward
the front of the vehicle. Remove the cover.5. Take out the engine air cleaner/filter and remove any
loose debris that may be found in the base.
6. Install a new engine air cleaner/filter element. See
ªNormal Maintenance Replacement Partsº in the Index.

6-18
Follow these steps to reinstall the engine air
cleaner/filter assembly:
1. Slide the lid into the slots in the front edge
of the base.
2. Pivot the cover and the air duct assembly
downward. Make sure that both latches are secure
and fully engaged.
3. Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
4. Tighten the air duct clamp.
5. Reconnect the IAT sensor.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the
Maintenance Schedule booklet.
CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
NOTICE:
If the air cleaner/filter is off, a backfire can cause
a damaging engine fire. And, dirt can easily
get into your engine, which will damage it.
Always have the air cleaner/filter in place when
you're driving.
