INSTALLATION
1. Install the field coil.
Be sure to align the coil′s pin with the hole in the compressor′s
front head.
2. Install the field coil harness clip using a screwdriver.
3. Install the pulley assembly using the installer and a hand press,
and then install the snap ring using snap ring pliers.
4. Install the clutch disc on the drive shaft, together with the original
shim(s). Press the clutch disc down by hand.
5. Using the holder to prevent clutch disc rotation, tighten the bolt
to 14 N·m (1.4 kg-m, 10 ft-lb) torque.
After tightening the bolt, make sure the pulley rotates smoothly.

CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/cm
2 , 50 psi) above 16°C (61°F). If less
than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa
(3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet h) to the
low-pressure side [evaporator drain hose i to shaft seal o (VK45DE) or n (VQ35DE)]. Refer to ATC-139,
"Components" . Perform a leak check for the following areas carefully. Clean the component to be
checked and move the leak detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure hoses, relief valve and shaft seal.
Liquid tank
Check the refrigerant connection.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer′s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7-10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. Face mode
c. Intake position: Recirculation
d. Max cold temperature
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4 through 6 above.

BIRDVIEW™
Description

Display area: Trapezoidal representation showing approximate
distances (Wn, D, and Wd).

Ten horizontal grid lines indicate display width while six vertical
grid lines indicate display depth and direction.

Pushing the “ZOOM IN” button during operation displays the
scale change and the view point height on the left side of the
screen.
The height of the view point increases or decreases when
“ZOOM” or “WIDE” is selected with the joystick.
MAP DISPLAY
Function of each icon is as follows:
1. Azimuth indication.
2. Position marker.
–The tip of the arrow shows the current location. The shaft of the
arrow indicates the direction in which the vehicle is traveling.
3. GPS reception signal (indicates current reception conditions).
4. Distance display (shows the distance in a reduced scale).

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger room.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting securing, or
insulating the component causing the noise.

An Allen wrench [2.5 mm (0.098 in)] is used for a stopper pin as
an example.
c. Insert plunger into the tensioner body by pressing timing chain
slack guide.
d. Keep slack guide pressed and hold plunger in by pushing stopper pin deeper through lever and into the
tensioner body hole.
e. Turn crankshaft pulley approximately 20° clockwise so that tim-
ing chain on the timing chain tensioner (primary) side is loose.
f. Remove mounting bolts and timing chain tensioner (primary).
CAUTION:
Be careful not to drop mounting bolts inside chain case.
8. Remove three water pump fixing bolts. Secure a gap between
water pump gear and timing chain, by turning crankshaft pulley

timing chain.
10. Remove M8 bolts and O-rings from water pump.
CAUTION:
Do not disassembly water pump.
INSPECTION AFTER REMOVAL

Check for badly rusted or corroded water pump body assembly.

Check for rough operation due to excessive end play.

If anything is found, replace water pump.
INSTALLATION
1. Install new O-rings to water pump.

Apply engine oil and engine coolant to O-rings as shown in
the figure.

Locate O-ring with white paint mark to engine front side.
2. Install water pump.
CAUTION:
Do not allow cylinder block to nip O-rings when install
water pump.

Make sure timing chain and water pump sprocket are
engaged.

Insert water pump by tightening mounting bolts alternately
and evenly.
3. Install timing chain tensioner (primary) as the following:
a. Remove dust and foreign material completely from backside of chain tensioner and from installation area
of rear timing chain case.
b. Turn crankshaft pulley clockwise so that timing chain on the timing chain tensioner (primary) side is loose.

Apply engine oil should be applied to the oil hole and tensioner, when installing timing chain
tensioner.

CAUTION:

When removing water pump, be careful not to get engine coolant on drive belt.

Water pump can not be disassembled and should be replaced as a unit.
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-36, "Chang-
ing Engine Coolant" and EM-241, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove following parts:

Engine front undercover

Air duct (inlet); Refer to EM-172, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt; Refer to EM-169, "DRIVE BELTS" .
3. Remove fan coupling with cooling fan, and then water pump pulley.
4. Remove water pump.

Engine coolant will leak from the cylinder block, so have a receptacle ready under vehicle.
CAUTION:

Handle the water pump vane so that it does not contact any other parts.
