< 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)

DRIVE BELTS
• When the lock nut is loosened
excessively, the idler pulley tilts an d the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt. CAUTION:
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lo ck nut should be in the condition at step“2”. If
the tension adjustment is performed when the lo ck nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.

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.

• 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".
