+Engine cover
+Intercooler
+Air inlet pipe
+Air cleaner case
+Throttle body
+Swirl and intake air control valve control solenoid valve and
bracket
+Vacuum tank
+Glow plate
+Rocker cover
+Spill tube
+Radiator shrouds (Rear and Lower)
+Cooling fan
+Radiator hose (Upper and Lower)
+Auxiliary belt and auto tensioner.
2. Remove the alternator.
3. Remove the A/C compressor and bracket with piping con-
nected. Move and support it at the LH side of engine bay with
a rope to avoid putting load on piping.
Refer to HA section in NISSAN Service Manual (Publication No.
SM9E-Y61CG2 or SM9E-Y61CG3).
4. Remove the chain cover, timing chain and other parts in con-
nection.

with No. 1 cylinder being positioned at TDC. Refer to the ®g-
ure. Refer to ªTIMING CHAINº, EM-37 in NISSAN Service
Manual (Publication No. SM9E-Y61CG2 or SM9E-Y61CG3).
CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
+Do not paint the match mark on the timing chain beforehand as
the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
+Do not drop or hit the sensor.
+Store in a clean place free of iron ®lings, etc.
+Do not place near any magnetic equipment.
6. Remove the water pump and its stud bolts.
