Loosen the locknut and turn the adjusting screw
until feeler gauge slides back and forth with a slight
amount of drag.

Inspection
1.Remove the cylinder head cover.
o Refer to page 6-33 when installing.
Inspect the timing belt for cracks and oil or coolant
soal(n9.
NOTE:
. Replace the belt if oil or coolant soaked.
. Remove any oil or solvent that gets on the belt.
2.
Rotate pulley
and inspect belt.
After inspecting. retorque the crankshaft pulley bolt
to 177 N'm (18.0 kgf.m, 130 lbnft).
CAUTION: Always adiust iiming belt lension with the
engin€ cold.
NOTE:
. The tensioner is spring-loaded to apply proper ten-
sion to the belt automatically after making the follow-
ing adjustment.
. Alwavs rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adjustment of the belt ten-
ston.
Remove the cylinder head cover. (Refer to page
6-33 when installing.)
Set the No. I piston at TDC (see page 6-12).
Rotate the crankshaft five to six revolutions to set
the belt.
Set the No. 1 piston at TDC.

Eight numbers (1 to 8) are printed on the surlace ol
the filter.
The lollowing explains the procedure for tightening
filters using these numbers.
1) Make a mark on the engine oil cooler (818c5
engine) or cylinder block (8188'1, 818C1 engines)
under the number that shows at the bottom of
the filter when the rubber seal is seated.
2) Tighten the filter by turning it clockwise seven
numbers Irom the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point

5. After installation, fill the engine with oil up to the
specilied level, run the engine for more than 3 min-
utes, then check for oil leakage and oil level.
CAUTION: Installation using other than the above
procedure could result in serious engine damage
duo to oil leakage.

Inspection
Remove the timing belt (81881 engine: see page 6-10, B'l8Cl,818C5 engines: see page 6-48).
Tu.n the water pump pulley counterclockwise.Check that it turn freely.
Check for sign6 of seal leakage.
NOTE: A small amount of "weeping" trom thebleed hole is normal.

Troubleshooting Procedures
Checking the Diagnostic Trouble Code (DTC)
with an OBD ll Scan Tool or th€ Honda PGM Tester
When the TCM senses an abnormality in the input or output systems, the lD,] indicator light in the gauge assembly will
blink. When the 16p Data Link Connector (DLC) (located under the dash on the passenger side) is connected to the OBD ll
Scan Tool or Honda PGM Taster as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) when
the ignition switch is turned ON {ll}.
When the !r indicator light has been reported on, connect the OBD ll Scan Tool confirming to SAE J1978 or Honda PGM
Tester to the DLC (16P) behind the ashtray. Turn the ignition switch ON (ll) and observe the DTC on the screen ofthe OBD
ll Scan Tool or Honda PGM Tester. After determining the DTC, refer to the electrical system Symptom-to-Component
Chart on pages 14-54 and 14-55.
NOTE: SeetheOBDll ScanTool orHonda PGM Tester user's manual for specific instructions.
OBD-IlSCAN TOOL orHONDA PGM TESTER
Some PGM-Fl problems will also make the lol indicator light come on. After repairing the PGM-Fl system. disconnect the
BACK Up fuse (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then recheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get
the customer's code number, and make note of the radio presets before removing the fuse so you can reset them

When the TCM senses an abnormality in the input or output systems, the [D;l indicator light in the gauge assembly willblink.
When the Service Check Connector (located under the dash on the passenger side) is connected with the special tool asshown, the E1T indicator light will indicate (blink) the Diagnostic Troubte Code (DTC) when the ignition switch is turned ON{

When the @ indicator light has been reported on, connect the Service Check Connector with the special toot.
GAUGE ASSEMEI.Y
Then turn ON (ll) the ignition switch and observe the E indicator light.Codes 1 through 9 are indicated by individual short blinks. Codes 1O and above are indicated by a series of long and shortblinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the code. After deter-mining the code, refer to the electrical system Symptom-to-Component Chart on pages 14-S4 and 55.

1. Turn the ignition switch OFF.
2. Remove the No. 47 BACK UP fuse {7.8 A) from the under-hood fuse/relay box for lO seconds to reset the TCM.
NOTE:
. Disconnecting the No, 47 BACK UP fuse also cancels the radio anti-theft code, preset stations and clock setting, Get thecustomer's code number, and make note of the rsdio presets before removing the fuse so you can reset them.o The TCM memory cannot be cleared by using the OBD ll Scan Tool or Honda pGM Tester; be sure to remove the BACKUP fuse to reset the TCM.
