5. Run the engine for more than 3 minutes, then checkfor oil leakage.
6. Turn the ignition switch to LOCK (0).
7. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
8. Turn the ignition switch to ON (II).
9. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
10. Select GAUGES in the BODY ELECTRICAL menu with the HDS.
11. Select ADJUSTMENT in the GAUGES menu with the HDS.
12. Select SERVICE REMINDER in the ADJUSTMENT menu with the HDS.
13. Select RESET in the SERVICE REMINDER menu with the HDS.
14. Select RESETTING THE ENGINE OIL LIFE with the HDS.
NOTE: If you changed the automatic transmission
fluid (ATF) at the same time with the engine oil,
select RESETTING THE ENGINE OIL LIFE AND ATF
with the HDS instead. Oil filter wrench 07HAA-PJ70101
1. Remove the oil filter with the oil filter wrench.
2. Inspect the filter to make sure the rubber seal is not stuck to the oil filter seating surface of the engine.
3. Inspect the threads (A) and rubber seal (B) on the new filter. Clean the seat on the engine block, then
apply a light coat of new engine oil to the filter
rubber seal. Use only filters with a built-in bypass
system.
4. Install the oil filter by hand.
5. After the rubber seal seats, tighten the oil filter clockwise with the oil filter wrench.

8. Connect the positive crankcase ventilation (PCV) hose (A), the evaporative emission (EVAP) canister
hose (B) and the brake booster vacuum hose (C).
9. Install the harness holder (A) to the bracket, then install the ground cable (B) and the harness clamp
bracket (C).
10. Connect the engine wire harness connectors, and install the wire harness clamps to the intake
manifold:
 Four fuel injector connectors
 Manifold absolute pressure (MAP) sensor connector
 Throttle actuator connector 11. Install the intake air duct (A), then connect the
vacuum hose (B) and breather pipe (C).
12. Install the engine cover.
13. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation three times, then check
for fuel leakage at any point in the fuel line.
14. Clean up any spilled engine coolant.
15. After installation, check that all tubes, hoses and connectors are installed correctly.
16. Refill the radiator with engine coolant, and bleed the air from the cooling system with the heater
valve open (see step 6 on page 10-8).

10. Install the exhaust manifold, and tighten the bolts and nuts in a crisscross pattern in three steps, beginning with the inner bolt.
11. Install the other parts in the reverse order of removal.
12. Inspect for leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation three times, then check for fuel leakage at any point
in the fuel line.
13. Refill the radiator with engine coolant, and bleed the air from the cooling system with the heater valve open (see step 6 on page 10-8).

1. Wait until the engine is cool, then carefully removethe radiator cap.
2. Start the engine. Set the heater temperature control dial to maximum heat, then turn the ignition switch
to LOCK (0). Make sure the engine and the radiator
are cool to the touch.
3. Loosen the drain plug (A), and drain the coolant.
4. After the coolant has drained, tighten the radiator drain plug securely.
5. Remove, drain, and reinstall the coolant reservoir.
6. Fill the coolant reservoir to the MAX mark (A) with Honda Long Life Antifreeze/Coolant Type 2 (P/N
CA66688). 7. Pour Honda Long Life Antifreeze/Coolant Type 2
into the radiator up to the base of the filler neck.
NOTE: Always use Honda Long Life Antifreeze/Coolant Type 2. Using a non-Acura coolant can result in
corrosion, causing the cooling system to
malfunction or fail.
 Honda Long Life Antifreeze/Coolant Type 2 is a mixture of 50 % antifreeze and 50 % water. Do
not add water.

8. Loosely install the radiator cap.
9. Set the heater temperature control dial tomaximum heat.
10. Start the engine, and let it run until it warms up (the radiator fan comes on at least twice).
11. Turn off the engine. Check the level in the radiator, and add Honda Long Life Coolant/Antifreeze
Type 2, if needed.
12. Install the radiator cap securely, then start the engine again, and check for leaks.
13. Clean up any spilled engine coolant.
14. If the maintenance minder required engine coolant replacement, reset the maintenance minder
(see page 3-6), and this procedure is complete. If
the maintenance minder did not require engine
coolant replacement, go to step 15.
15. Turn the ignition switch to LOCK (0).
16. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
17. Turn the ignition switch to ON (II).
18. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
19. Select GAUGES in the BODY ELECTRICAL menu with the HDS.
20. Select ADJUSTMENT in the GAUGES with the HDS.
21. Select SERVICE REMINDER in the ADJUSTMENT menu with the HDS.
22. Select RESET in the SERVICE REMINDER menu with the HDS.
23. Select MAINTENACE SUB ITEM 5 RESET menu with the HDS.

9. Check for continuity between fan control relay 5P
socket terminal No. 1 and radiator fan motor 2P
connector terminal No. 1.
Check for poor connections or loose
terminals at the under-hood fuse/relay box, the
radiator fan motor, and body ground (G 301), then
go to step 1.
Repair open in the wire between fan control
relay 5P socket terminal No. 1 and radiator fan
motor 2P connector terminal No. 1. 10. Turn the ignition switch to ON (II).
11. Measure the voltage between radiator fan relay 4P
socket terminal No. 3 and body ground.
