GENERAL
OUTLINE OF CHANGES
Some service procedures have been revised as the following changes have been made to comply to
the Emission Regulation StepIII.
DInjection timing and idle speed check and adjustment have bee changed as the electronic-controlled
fuel injection pump has been introduced.
DThe oil pan has a cover in order to reduce noise due to an enhanced engine output.
DA crank angle sensor and crankshaft sensing blade have been added due to the introduction of
an electronic-controlled fuel injection pump. Due to this change, the timing belt front lower cover
has been reshaped.
DThe tightening torque of the cylinder head bolts and the cylinder head gasket have been changed.
