Pull the lower primary radiator hose spring clip up until the end of the clip is in the detent on the quick connect coupling and disconnect the lower primary radiator hose from the primary radiator.

- To install, push the spring clip in place and connect the lower primary radiator hose quick connect coupling, making sure the coupling is secure.






22. Release the clamp and disconnect the secondary radiator-to-transmission fluid cooler hose from the secondary radiator.

23. Remove the nut and disconnect the A/C condenser outlet fitting.
- Remove and discard the O-ring seal and the gasket.

- To install, tighten to 15 Nm (133 lb-in).


24. Release the clamp and disconnect the Charge Air Cooler (CAC) and fuel cooler-to-secondary degas bottle hose from the secondary degas bottle. Position the hose aside.

25. Remove the bolt and position the power steering fluid reservoir aside.
- To install, tighten to 7 Nm (62 lb-in).


26. NOTE: The quick connect coupling illustrated is to show the spring clip release location only. The quick connect coupling on the hose may differ.
Pull the upper primary radiator hose spring clip up until the end of the clip is in the detent on the quick connect coupling and disconnect the upper primary radiator hose from the primary radiator.
