CAUTION:
- If the hose clamp is not tightened sufficiently, the charge air cooler outlet hose could become disconnected, and if it is tightened excessively, it may damage the charge air cooler outlet hose and charge air cooler outlet pipe. Therefore, assemble the end of the hose clamp so that it rides on the white line.
Tighten the hose clamp until the clamp end rides on top of the white line.
