id0113z7801900

Warning

• A hot engine and intake air system can cause severe burns. Turn off the engine and wait until they are cool before removing the intake-air system.

Note

• Rubber sealing (fluorine) for the connector part of the charge air cooler air inlet hose may be stuck. In addition, oil may be present on the sealing surface of the charge air cooler air inlet hose and charge air cooler air outlet hose. When replacing, always clean the sealing surface and inspect the hose inner surface.

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

2. Remove in the order shown in the figure.

3. Install in the reverse order of removal.

Hose Clamp Installation Note

1. Visually inspect the charge air cooler outlet hose and charge air cooler outlet pipe.

• Replace damaged or cracked parts.

2. Use a clean cloth to clean the outer surfaces of the charge air cooler outlet pipe and the charge air cooler outlet hose.

am3zzw00016736

3. Temporarily install a new hose clamp to the charge air cooler outlet hose. (Do not tighten hose clamp)

Note

• Installation can be facilitated by pointing the clamp in the direction shown in the figure.

am3zzw00016737

Caution

• When installing the hose, do not apply oil to the area that was cleaned to prevent it from becoming disconnected.

4. Insert the charge air cooler outlet hose until it contacts the charge air cooler outlet pipe stopper.

am3zzw00016738

5. Re-position the temporarily installed hose clamp to the position 5—7 mm {0.20—0.27 in} from the charge air cooler outlet pipe stopper.

am3zzw00016739

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.

6. Tighten the hose clamp until the clamp end rides on top of the white line.
