Removal guidelines
 
A


Removing the drive belt
The following operations are necessary because the engine uses a
serpentine drive system with auto-tensioner.
1. Insert a 12.7sq spinner handle into the auto-tensioner tool hole,
and turn the auto-tensioner in an anti-clockwise direction before
it reaches the stopper.
2. Align hole A and hole B, insert an L-shaped hexagonal Allen
Key, to hold the position, and remove the drive belt.
Caution
If planning to re-use the drive belt, ensure that it will be
refitted the same way round, by marking the back of the belt
with chalk arrows indicating the direction of movement.
 
B


Removing the power steering oil pump and the A/C
compressor
1. Remove the power steering oil pump and the A/C compressor
from the bracket with the hoses intact.
2. Secure the removed power steering oil pump and the removed
A/C compressor with string, and put them somewhere where
they will not hinder the removal or fitting of the engine ASSY.
 
C



Removing the transfer ASSY and the transmission
ASSY
1. In order to prepare the special mechanical engine hanger
(MZ203830, MZ203831 or MB991928), the radiator support
upper insulator mounting bolts should be tightened on the
chassis (2 places).
2. Remove the transfer ASSY and the transmission ASSY.

Removing the engine mount bracket & stopper ASSY
1. Support the engine using a garage jack.
2. Remove the special mechanical engine hanger (MZ203830,
MZ203831 or MB991928).
3. Hold the engine ASSY using a chain block.
4. Support the engine oil pan component with the garage jack
through the engine block, so that the weight of the engine is not
taken by the engine mount bracket.
5. Loosen the nuts and bolts and remove the engine mount bracket
and stopper ASSY.
 
E


Removing the engine ASSY
After checking that all of the cables, hoses and harness connectors
etc have been disconnected, slowly hoist the engine using a chain
block and remove the engine from the engine compartment.
Fitting guidelines



A 
Fitting the engine ASSY
Install the engine whilst checking that cables, hoses and harness
connectors etc will not be squashed beneath it.

B 
Fitting the engine mount bracket & stopper ASSY
1. Support the engine oil pan component with the garage jack
through the engine block, and fit the engine mount bracket &
stopper ASSY whilst checking the position of the engine. Fix the
engine mount stopper so that the arrow points in the direction
shown in the diagram.
2. Support the engine ASSY with a garage jack.
3. Remove the chain block.
4. In the same way as when it was removed, hold the engine
ASSY with the special tool.
(1) <When using the special mechanical engine hanger
(MZ203830 or MZ203831)>
Install the special mechanical engine hanger (MZ203830
or MZ203831).
(2) <When using the special engine hanger (MB991928)>
Fit the following parts to the base hanger.
• Slide bracket (HI)
• Foot (standard) (MB991932)
• Joint (90) (MB991930)

Fitting the O-ring and the fuel high pressure hose
1. Apply a little fresh engine oil to the O-ring.
Caution
Ensure that no engine oil gets inside the deliver pipe.
2. Without damaging the O-ring, fit the fuel high pressure hose to
the delivery pipe by twisting it from left to right. Ensure that the
hose is twisted smoothly.
3. If the hose cannot be twisted smoothly, there is a possibility that
it may be biting into the O-ring, so remove the fuel high pressure
hose, and check for any damage to the O-ring. If the O-ring is
undamaged, reinsert it into the delivery pipe and check once
more whether the hose can be turned smoothly.
4. Tighten the mounting bolts for the fuel high pressure hose, to
the specified torque.
Tightening torque: 5.0 ± 1.0 N•m.

GENERAL
Servicing guidelines have been changed because of the changes listed below.
•Avariable valve timing control system (V.V.T.) has been adopted. Because of this, an oil feeder control valve and an intake
cam position sensor have been added.
•Amanifold absolute pressure (MAP) sensor has been added.
•An air temperature sensor has been added.
