- 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).
- Inspect the mating surfaces of the plastic or aluminum pipes. If it appears that the rubber elbow has moved on the plastic pipe, or if the hose clamps were loose, disassemble for further inspection.
- After disassembly of the plastic pipe from the rubber connection elbow, inspect the ends of the pipe for evidence of the rubber elbow rubbing on it. If chaffing marks are visible replace the worn pipe. Wipe any dust from the inside of the pipe.
- Check the inside of the rubber elbow for wear and contamination. If the rubber elbow is reusable, clean it internally with a shop towel, or soap and water. Blow-dry the elbow as needed, and install it.
- Check the condition of the gear clamp. If wear is evident, replace the gear clamp with a constant-torque clamp. Constant-torque clamps should be used if a vehicle is routinely exposed to rough road conditions or off-road applications.
- Check the two band clamps that hold the air cleaner in place on the cowl. Ensure the canister has not slipped downwards. If this condition is present, loosen the two band clamp bolts and slide the canister upward until the outlet pipe is properly aligned with the opening in the cowl.
- Inspect the alignment and fit of the rubber elbow that passes through the cowl and attaches the intake duct to the canister outlet pipe. Adjust as necessary to ensure a proper connection and tighten the clamps as follows: 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). Do not over-tighten the clamps.
