NOTE:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
The turbocharger compressor vanes can be damaged by even the smallest particles. When removing any turbocharger or engine air intake system component, ensure that no debris enters the system. Failure to do so may result in damage to the turbocharger.
NOTE:
Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.
NOTE:
If the components are to be reinstalled, they must be installed in their original location. Mark the components for installation into their original location.
NOTE:
Refer to the exploded view under the Engine Component View in the Description and Operation..
