Secondary Timing ChainNJEM0093CAUTION:
After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
When installing camshafts, chain tensioners, oil seals, or
other sliding parts, lubricate contacting surfaces with new
engine oil.
Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprockets, crankshaft pulley,
and camshaft brackets.
When removing the oil pans, oil pump assembly and tim-
ing chain from engine, first remove the crankshaft posi-
tion sensor (TDC sensor).
Be careful not to damage sensor edges.
Do not spill engine coolant on drive belts.
