  1. Check that the bolts on the canister mounting brackets are tight.
  2. Check the mounting angle of the air cleaner canister inlet boot. It must be rotated forward slightly to ensure a correct seal to the hood intake duct. Inspect the hood and boot contact points for proper contact as evident by the polished area on the hood where the boot contacts it.
  3. Check the connection points of the entire intake system to ensure the alignment of the rubber hoses to the charge air cooler pipe connections are correct. Check the piping for evidence of movement at the joint connections.
  4. Check the tightness and condition of the clamping hardware. Clamps at rubber-to-plastic duct connections should be tightened 39 to 41 lbf·in (440 to 460 N·cm), and clamps at rubber-to-metal duct connections should be tightened 90 to 100 lbf·in (1015 to 1130 N·cm). Replace any clamps that are corroded or fail to operate smoothly when tightened.
