outlet).
2. Pull the other end of the breather hose assembly away from the
airbox.
3. Remove the breather hose assembly from the vehicle.
4. Inspect the hoses for debris. Blow gently through the hoses to check

5. Check hoses for cracks, deterioration, abrasions or leaks. Replace as
needed.
6. Reinstall the hose assembly and secure the clamp at the engine.
Push the other end of the hose firmly into the airbox fitting.
NOTICE: Operation of the vehicle without breather hoses can cause engine
damage. Always reinstall a breather hose after removing it for
service.
Intake Pre-Filters
The engine intake pre-filter is located on
the right side of the cargo box. The PVT
intake pre-filter is located on the left side
of the cargo box.
Inspect both pre-filters before each use of
the vehicle to ensure adequate air flow. If
necessary, remove the pre-filters and
clean with soapy water. Dry with low
pressure compressed air.
NOTICE: When washing the vehicle, always
avoid spraying water directly
toward the PVT intake duct. See
page 126 for recommended
washing procedures.
