SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2006 December 2006 FX35/FX45
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. Sun-visor 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 compartment.
Causes of transmitted under-hood 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.

TIMING CHAIN
Revision: 2006 December 2006 FX35/FX45
8. Install internal chain guide, slack guide and timing chain ten- sioner (primary).
CAUTION:
Do not overtighten slack guide mounting bolts. It is normal
for a gap to exist under the bolt seats when mounting bolts
are tightened to the specification.
9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to remove plunger stopper tab from the rachet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten- sioner body hole.

The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.

2. Ream cylinder head recess diameter for service valve seat.

Be sure to ream in circles concentric to valve guide center.
This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. WARNING:
Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.
5. Using the valve seat cutter set (commercial service tool) or valve seat grinder, finish seat to the specified dimensions. Refer to
EM-157, "
Valve Seat" .
CAUTION:
When using the valve seat cutter, firmly grip cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to EM-110, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set a try square along the side of valve spring and rotate spring.
Measure the maximum clearance between the top of spring and
try square.

If it exceeds the limit, replace valve spring. Oversize [0.5 mm (0.020 in)]
Intake : 38.500 - 38.516 mm (1.5157 - 1.5164 in)
Exhaust : 32.700 - 32.716 mm (1.2874 - 1.2880 in)

When installing, align connecting rod bearing stopper protru-
sion with cutout of connecting rods and connecting rod bear-
ing caps to install.

Ensure the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.
12. Install piston and connecting rod assembly to crankshaft.

Position crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.

Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.

Match the cylinder position with the cylinder number on connecting rod to install.

Be sure that front mark on piston crown is facing front of engine.

Using a piston ring compressor (SST) or suitable tool, install
piston with the front mark on the piston crown facing the front
of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.
13. Install connecting rod bearing cap.

Match the stamped cylinder number marks on connecting rod
with those on connecting rod bearing cap to install.

Be sure that front mark on connecting rod bearing cap is fac-
ing front of the engine.
14. Tighten connecting rod bolt as follows:
a. Inspect the outer diameter of connecting rod bolt. Refer to EM-150, "
CONNECTING ROD BOLT OUTER
DIAMETER" .
b. Apply engine oil to the threads and seats of connecting rod bolts.
c. Tighten connecting rod bolts.

VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within the specifications, perform this procedure.

Apply prussian blue (or white lead) onto contacting surface of
valve seat to check the condition of the valve contact on the sur-
face.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has “NG” conditions even after the re-check,
replace valve seat. Refer to EM-241, "
VALVE SEAT REPLACE-
MENT" .
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess in cylinder head. Set the machine depth stop to ensure this. Refer to EM-280, "
Va l v e S e a t" .
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.

Be sure to ream in circles concentric to valve guide center.
This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. CAUTION:

Avoid directly touching cold valve seats.

Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set (commercial service tool) or valve seat grinder, finish seat to the specified dimensions. Refer to

15. Tighten connecting rod nuts as follows:
a. Apply new engine oil to the threads and seats of connecting rod bolts and nuts.
b. Tighten connecting rod nuts.
c. Then tighten all connecting rod nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening connecting rod nuts, make sure that crank-
shaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-265,
"CONNECTING ROD SIDE CLEARANCE" .
