Air Induction System
WARNING
To prevent personal injury and / or death,
or
damage
to
property,
when
performing
maintenance and repairs to any turbocharged
engine with engine air inlet piping disconnected,
a turbocharger compressor air inlet protective
shield should be installed over the turbocharger
air inlet. Order the protective shield for engines
from your local IC Bus
®
dealer.
Perform a complete inspection of the air induction system.
Disassemble the joints of each aluminum component and
inspect for salt build up and chlorine that can cause aluminum
particles to flake off and enter the engine combustion chambers.
If corrosion is present (usually appears at the pipe connections),
use a wire brush to clean the inside of the pipes and inside
the rubber hoses.
Clean all components thoroughly before
reassembly.
If the intake pipes are pitted at the joint ends, Room Temperature
Vulcanizing (RTV) silicone may be used to seal the joints.
Ensure that no excess sealant is on the inside of the pipe that
can be pulled into the engine. If the service condition of the
pipes, hoses, or clamps is questionable, replace them.
•
Check for loose hoses and clamps.
•
Check for ruptured or collapsed hoses.
•
Check air cleaner housing for cracks.
Air Cleaner Element Service
NOTE: Do not change the air cleaner element configuration
from the factory installed configuration. If equipped with
a single element or dual element that configuration must
stay with the vehicle. Failure to comply may affect engine
performance.
