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 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.

How to Troubleshoot Circuits at the ECM/
PCM Connectors
11-6 Fuel and Emissions Systems
General Troubleshooting Information (cont’d)

B
A
C A
B D
C
A
NOTE: The ECM/PCM overwrites data and monitors the
EVAP system for about 30 minutes after the ignition
switch is turned to LOCK (0) or ACC (I). Jumping the
SCS line after turning the ignition switch to LOCK (0) or
ACC (I) cancels this function. Disconnecting the ECM/
PCM during this function, without jumping the SCS line
first, can damage the ECM/PCM.
1. Make sure the ignition switch is turned to LOCK (0), then jump the SCS line with the HDS.
2. Remove the cover (A).
3. Lift up the under-hood fuse/relay box (D).
4. Remove the coolant reservoir (E). Disconnect ECM/ PCM connectors A, B, and C, and probe the
terminals from the terminal side of the connectors.
NOTE: ECM/PCM connectors A, B, and C have
symbols (A= , B= , C= ) embosed on them for
identification. 5. When diagnosis/troubleshooting is done at the
ECM/PCM connector, use the terminal test port (A)
above the terminal you need to check.
6. Connect one side of the patch cord’s terminals (A) to a commercially available digital multimeter (B),
and connect the other side cord’s terminals (C) to a
commercially available banana jack (Pomona
Electronics Tool No. 3563 or equivalent) (D).
7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the
tips into the terminals.
 For accurate results, always use the pin probe (male).
 To prevent damage to the c onnector
terminals, do not insert test equipment
probes, paper clips, or other substitutes as
they can damage the terminals. Damaged
terminals cause a poor connection and an
incorrect measurement.
 Do not puncture the insulation on a wire. Punctures can cause poor or intermittent
electrical connections.
