< PRECAUTION >[HR16DE]
PRECAUTIONS
• After removing the bolts and nuts, separate the mating surface and
remove the sealant using Tool.
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the RTV Silicone Sealant is applied.
Use a plastic hammer to slide the cutter (2) by tapping on the side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old Silicone RTV Sealant adhering to the gasket application surface and the mating surface.
• Remove the sealant completely from the groove of the gasketapplication surface, bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the sealant tube to the tube presser. Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-42, "
Recommended Chemical Product and Sealant".
4. Apply the sealant without breaks to the specified location using Tool.
• If there is a groove for the s ealant application, apply the seal-
ant to the groove.
• As for the bolt holes, normally apply the sealant inside the holes. If specified, it should be applied outside the holes. Make
sure to read the text of this manual.
• Within five minutes of the seal ant application, install the mat-
ing component.
• If the sealant protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill the engine with the specified oil and coolant. Refer to MA-14,
"Fluids and Lubricants".
CAUTION:
Follow all specific instructions in this manual. Tool number : KV10111100 (J-37228)

CheckingINFOID:0000000005930924
• Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
• Visually check belts for wear, damage, and cracks on inside and edges.
• Turn crankshaft pulley two times clockwise, and make sure tension on all pulleys is equal before doing the test.
• When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency with acous tic tension gauge at the ( ) marked point.
CAUTION:
• When the tension and frequency are measured, the acoustic tension gauge should be used.
• When checking immediately after installation, first ad just it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the sp ecified value to avoid variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000005930925
CAUTION:
• When belt is replaced with new one, adjust belt te nsion to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
• When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
• When installing a belt, make sure it is correctly engaged with the pulley groove.
• Never allow oil or engine coolant to get on the belt.
• Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position with the specified torque by 45 degrees.

Inspection and AdjustmentINFOID:0000000005930930
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-46, "
Exploded View".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (2) clockwise and align TDC mark(without paint mark) (A) to timing indicator (1) on front cover.
• At the same time, make sure that both intake and exhaust cam noses of No. 1 cylinder face inside as shown.
• If they do not face inside, rotate crankshaft pulley once more (360 degrees) and align as shown.
b. Use a feeler gauge, measure the clearance between valve lifter and camshaft.
• Measure the valve clearances at locations marked “× ” as
shown in the table below [locations indicated with black arrow
( ) as shown] with a feeler gauge.

c. Rotate crankshaft pulley (2) one revolution (360 degrees) and
align TDC mark (without paint mark) (A) to timing indicator (1) on
front cover.
• Measure the valve clearance at locations marked “ ×” as shown
in the table below [locations indicated with black arrow ( ) as
shown] with a feeler gauge.
3. If out of standard, perform adjustment procedure.
ADJUSTMENT
• Perform adjustment depending on selected head thickness of valve lifter.
1. Remove camshaft. Refer to EM-59, "
Exploded View".
2. Remove valve lifters at the locations that are out of the standard.
3. Measure the center thickness of the removed valve lifters with a micrometer (A).
4. Use the equation below to calculate valve lifter thickness for replacement.

• Thickness of new valve lifter (B) can be identified by stamp
mark (A) on the reverse side (inside the cylinder).
• Stamp mark “300” indicates 3.00 mm (0.118 in) in thickness.
NOTE:
Available thickness of valve lifter: 26 sizes range 3.00 to 3.50 mm (0.1181 to 0.1378 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory). Refer to EM-112, "
Camshaft".
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-59, "
Exploded View".
7. Manually rotate crankshaft pulley a few rotations.
8. Make sure that valve clearances for cold engine are wit hin specifications by referring to the specified val-
ues.
9. Install all removed parts in the reverse order of removal.
10. Warm up the engine, and check for unusual noise and vibration.

COMPRESSION PRESSURE
COMPRESSION PRESSURE
InspectionINFOID:0000000005930931
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-499, "
Inspection".
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-46, "
Exploded View".
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial service tool) (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plughole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use fully a charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, c heck battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
• If compression pressure is below minimum val ue, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, pi ston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Repl ace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low co mpression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-114, "
Description".

INTAKE MANIFOLD
7. Remove intake manifold support front (1) and bolt from rear (2).
• Bracket (2) is not removed. Remove bolt from intake manifold.
8. Remove intake manifold. • Loosen bolts in the reverse of the order shown.
9. Remove EVAP canister purge volume control solenoid valve from intake manifold, if necessary. CAUTION:
Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.
10. Remove intake manifold support (center) from cylinder head, if necessary. NOTE:
The intake manifold support (center ) functions as the guide when the intake manifold is installed.
INSTALLATION
Installation is in the reverse order of removal.
Intake Manifold
1. Install the gasket to the intake manifold.
• Align the protrusion (A) of gasket to the groove of intake mani-fold.
2. Place the intake manifold into the installation position. CAUTION:
Make sure that the oil level gauge guide is not di sconnected from the fixing clip of water inlet due
to interference with intake manifold.
