CAUTION:
●All applicable local laws regarding the towing operation must be obeyed.
●It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.
●Always attach safety chains before towing.
●When towing, make sure that the transmission, steering system and power train are in good order.
If any unit is damaged, dollies must be used.
●Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
NISSAN recommends that towing dollies be used when towing your
vehicle beplaced on a flat bed truck as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
Observe the following restricted towing speeds and distances.
CAUTION:
Never tow an automatic transaxle model from the rear (i.e., backward) with four wheels on the ground
as this may cause serious and expensive damage to the transaxle.

●Alternator
●Drive belt auto-tensioner; Refer to EM-13, "REMOVAL" .
●Exhaust front tube; Refer to EX-2, "Removal and Installation" .
2. Remove A/C compressor from engine. Temporarily secure A/C compressor to vehicle side with a rope to
avoid putting a load on them.
3. Remove bracket mounting bolts for fixing A/C piping on right strut housing and exhaust manifold cover.
Doing so simplifies moving.
4. Move power steering pump with piping connected, and secure it to vehicle side temporarily.
5. Pull power steering reservoir tank out of brackets to move power steering piping.
CAUTION:
To avoid power steering fluid leakage, temporarily fix reservoir tank vertically.
6. Suspend engine with a hoist, and support the engine posture.
For installation of engine slingers, refer to EM-69, "
ENGINE ASSEMBLY" .
7. Remove RH engine mount insulator.
8. Remove center member and rear engine mounting bracket.
9. Drain engine oil.
10. Remove oil pan upper and lower, and oil strainer. Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
11. Remove intake valve timing control cover.
a. Loosen bolts in reverse order shown in the figure.
b. Remove the cover using Tool (Seal cutter).
CAUTION:
Be careful not to damage mounting surface.
12. Pull chain guide between camshaft sprockets out through front
cover.
13. Set No. 1 cylinder at TDC on its compression stroke with the fol-
lowing procedure.
a. Rotate crankshaft pulley clockwise and align mating marks to
timid indicator on front cover.

5. Install timing chain and related parts.
●Install by lining up mating marks on each sprocket and timing
chain.
NOTE:
Before installing chain tensioner, it is possible to change the
position of mating mark on timing chain for that on each
sprocket for alignment.
CAUTION:
For the above reason, after the mating marks are aligned,
keep them aligned by holding them with a hand.
●Before and after installing chain tensioner, check again to
make sure that mating marks have not slipped.
●After installing chain tensioner, remove stopper pin, and make
sure that tensioner moves freely.
●To avoid skipped teeth, do not move crankshaft and camshaft
until front cover is installed.
6. Install front oil seal to front cover.
●Using a drift of 56 mm (2.20 in) dia, press oil seal in until it is
flush with front end surface of front cover.
CAUTION:
Be careful not to cause damage or burr to circumference of
oil seal.
7. Install front cover with the following procedure.
a. Install O-rings to cylinder head and cylinder block.
b. Apply liquid gasket to positions specified in the figure.
Use Genuine Liquid gasket or equivalent.
●Application instruction differs depending on the part.
c. Make sure that mating marks of timing chain and each sprocket
are still aligned. Then install front cover.
CAUTION:
●Do not let air conditioning and power steering piping
interfere with upper part of front cover.
●Be careful not to damage front oil seal by interference
with front end of crankshaft.
