Engine Air Cleaner/Filter

When to Inspect the Engine Air Cleaner/Filter

Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mile) interval. See Maintenance Schedule  for more information.

If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.

See Engine Compartment Overview  for the location of the engine air cleaner/filter.

How to Inspect the Engine Air Cleaner/Filter

To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter (away from vehicle) to release loose dust and dirt. If the filter remains covered with dirt, a new filter is required.

To inspect or replace the engine air cleaner/filter:

1. Remove the engine cover.

See Engine Cover

A. Ventilation Tube
B. Sensor

2. Disconnect the cover fitting from the ventilation tube (A).
3. Disconnect the wiring harness connector from the sensor (B).

A. Clamp
B. Screws
C. Housing Cover
D. Filter
E. Base

4. Loosen the outlet duct clamp (A).
5. Loosen the six housing cover (C) screws (B).
6. Remove the housing cover (C) with outlet duct.
7. Remove the filter (D) and any loose debris that may be found in the base (E).
8. Inspect or replace the filter (D).

WARNING
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 helps to stop flames if the engine backfires. Use caution when working on the engine and do not drive with the air cleaner/filter off.

Notice: If the air cleaner/filter is off, dirt can easily get into the engine, which could damage it.

Always have the air cleaner/filter in place when you are driving.

Cooling System

The cooling system allows the engine to maintain the correct working temperature.

A. Engine Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Cooling Fans (Out of View)

WARNING
An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan.

WARNING
Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned.

Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle

Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 mi) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty.

Always use DEX-COOL (silicate-free) coolant in the vehicle.
