1. Wait until the engine is cool, then carefully removethe radiator cap (A). Wet the radiator cap seal with
engine coolant, then install it on a commercially
available pressure tester (B).
2. Apply a pressure of 93 123 kPa (0.95 1.25 kgf/cm , 14 18 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap. 1. Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the base of the filler neck.
2. Attach a commercially available pressure tester (A) to the radiator, and apply a pressure of 93 123 kPa
(0.95 1.25 kgf/cm , 14 18 psi).
3. Inspect for engine coolant leaks and a drop in pressure.
4. Check for engine oil in the coolant and/or coolant in the engine oil.
5. Remove the tester, and reinstall the radiator cap.

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.
