Noises when you turn your diesel off

[sbbamafan]

I noticed when I turn my diesel off it makes a bunch of weird ticking noises - sort of sounds like a loud clock ticking.  Does everybody's do that?  Normal?

It's normal. 

 

 

Normal Sounds After Engine Shut-Off

After the 3.0L diesel engine has been shut off, several sounds may be heard in the engine bay. These sounds may be caused by the following components performing a cleaning cycle:

• Turbocharger linkage (Fig. 9)
• Exhaust throttle valve
• Intake manifold swirl valve

The sounds are normal operating characteristics of the vehicle and do not impact the designed performance or reliability of the vehicle.
