1. Remove the drive belt (see page 4-31).

2. Drain the engine coolant (see page 10-8).

3. Remove the drive belt auto-tensioner pulley

(see page 4-33).

4. Remove the crankshaft pulley (see page 6-16).

5. Remove the oil cooler joint pipe (A), then remove

the seven bolts securing the water pump. Remove
the water pump (B).

6. Inspect, and clean the O-ring groove and mating

surface of the water passage.

7. Install the water pump with new O-rings (C) and the

oil cooler joint pipe.

8. Clean up any spilled engine coolant.

9. Install the crankshaft pulley (see page 6-17).

10. Install the drive belt auto-tensioner pulley

(see page 4-33).

11. Install the drive belt (see page 4-31).

12. 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. Check the coolant level in the coolant reservoir.

Make sure it is between the MAX mark (A) and MIN
mark (B).

2. If the coolant level in the coolant reservoir is at or

below the MIN mark, add coolant to bring it up to
the MAX mark, then inspect the cooling system for
leaks.

1. Wait until the engine is cool, then carefully remove

the 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 to

maximum 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.
