EC-678
< PRECAUTION >[HR16DE (WITHOUT EURO-OBD)]
PRECAUTIONS
When measuring ECM signals with a circuit tester, never allow
the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
Do not use ECM ground terminals when measuring input/out-
put voltage. Doing so may result in damage to the ECM’s tran-
sistor. Use a ground other than ECM terminals, such as the
ground.
Do not operate fuel pump when there is no fuel in lines.
Tighten fuel hose clamps to the specified torque.
Do not depress accelerator pedal when starting.
Immediately after starting, do not rev up engine unnecessar-
ily.
Do not rev up engine just prior to shutdown.
When installing C.B. ham radio or a mobile phone, be sure to
observe the following as it may adversely affect electronic
control systems depending on installation location.
-Keep the antenna as far as possible from the electronic con-
trol units.
-Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
-Adjust the antenna and feeder line so that the standing-wave
ratio can be kept smaller.
-Be sure to ground the radio to vehicle body.

ENGINE RUNNING
No work should be carried out on the hydraulic system while engine is running.
Remember that fuel pressure values in hydraulic circuit can reach up to 1,600 bar.
Keep hands or face (particularly eyes) out of any high pressure leak.
Recall that fuel is dangerous for health.
FUEL RAIL PRESSURE SENSOR
Under warranty, do not remove the fuel rail pressure sensor from the rail.
Do not try to measure the resistance of the fuel rail pressure sensor. This test is destructive for the
internal components.
FUEL INJECTOR
Fuel injectors are driven by over 100V.
FUEL injector electronics are polarised. In case of intervention on wiring harness, do not
invertwires. It is destructive for the piezo components.
Do not drive the fuel injectors if their body is not connected to the battery ground (risk ofelectro-
static discharge). For instance, fuel injector body have to be in contact with cylinder.
Piezo fuel injector connector must not be unplugged while engine is running. Risk of majordamage
to the engine (fuel injector could stay opened).

Cleanliness
RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated withcon-
tamination are:
 damage to or destruction of the high pressure injection system,
 components jamming,
 components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the fuel injectors.
What are the sources of contamination?
 metal or plastic chips,
 paint,
fibres:
- from cardboard,
- from brushes,
- from paper,
- from clothing,
- from cloths,
 foreign bodies such as hair,
 ambient air
etc.
NOTE:
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create electrical connection malfunction.

TIMING CHAIN
9. Remove front cover with the following procedure:
a. Loosen bolts in the reverse of the order shown.
b. Cut liquid gasket by prying the position ( ) shown, and then
remove the front cover.
10. Remove front oil seal from front cover.
 Remove by lifting it up using a suitable tool.
CAUTION:
Be careful not to damage the front cover.
11. Remove chain tensioner (1) with the following procedure.
a. Fully push down the chain tensioner lever (A), and then push the
plunger (C) into the inside of tensioner.
 The tab (B) is released by fully pushing the lever down. As a
result, the plunger can be moved.
b. Pull up the lever to align its hole position with the body hole posi-
tion.
 When the lever hole is aligned with the body hole position, the
plunger is fixed.
 When the protrusion parts of the plunger ratchet and the tab
face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then fix the lever at the upper
position.
 The example that a hexagonal wrench for 2.5 mm (0.098 in) is used as shown.
d. Remove chain tensioner.

c. Install chain tensioner (1).
 Insert the body into the shaft (B) while inserting the spring into
the fixing hole (A) of cylinder block front surface.
 Make sure that the tension is applied to the oil pump drive
chain after installing.
2. Install timing chain with the following procedure.
 Install by aligning matching marks on each sprocket and tim-
ing chain.
 If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
 Check matching mark position of each sprocket and tim-
ing chain again after installing the timing chain, keep
matching marks aligned by holding them with a hand.
 To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
3. Install timing chain tension guide (2) and timing chain slack
guide (1).
4. Install chain tensioner (1).
 Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.
 Securely pull out the stopper pin after installing the chain ten-
sioner.

Exploded
View".
Removal
1. Install engine slinger to cylinder head front left side (A) and rear
right side (B) and support the engine with a hoist.

 A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
the position not specified.
14. Remove front oil seal from front cover.
 Lift up front oil seal using a suitable tool.
CAUTION:
Be careful not to damage front cover.
15. Push in timing chain tensioner plunger.
16. Insert a stopper pin (A) into the body hole to retain the plunger in
collapsed position.
NOTE:
Use approximately 1.5 mm (0.059 in) diameter. hard metal pin
as a stopper pin.
17. Remove timing chain tensioner (1).
18. Remove timing chain slack guide (2), timing chain tension guide
(3) and timing chain (1).
CAUTION:
Never rotate each crankshaft and camshaft individually
while timing chain is removed. It causes interference
between valve and piston.
