All vehicles
CAUTION:
A new oil cooler must be installed or severe damage to the engine can occur.
CAUTION:
Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surface. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove all traces of sealant.
CAUTION:
This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30" or "30RFF" (orange in color).
NOTE:
LH shown, RH similar.
CAUTION:
The OEM pulley is pressed on 4.74 mm (0.18 in) past flush of the end of the camshaft. The service pulley is pressed on flush to the end of the camshaft.
CAUTION:
To make sure of correct sealing, do not scratch the camshaft.
CAUTION:
Cylinder head camshaft journal caps and cylinder heads are numbered to verify that they are assembled in their original positions.
NOTE:
RH shown, LH similar.
NOTE:
The camshaft caps have alignment dowels.
CAUTION:
The camshaft roller followers must be installed in their original positions.
NOTE:
RH shown, LH similar.
NOTE:
