REMOVAL
1. Drain engine coolant. Refer to CO-8, "DRAINING ENGINE COOLANT" .
CAUTION:
Perform this step when the engine is cold.
2. Remove drive belt auto-tensioner. Refer to EM-37, "
TIMING CHAIN" .
3. Remove water pump.
CAUTION:

Handle water pump vane so that it does not contact any other parts.

Water pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL

Visually check that there is no significant dirt or rusting on water
pump body and vane (A).

Make sure that there is no looseness in vane shaft, and that it
turns smoothly when rotated by hand.

Replace water pump, if necessary.
INSTALLATION
Installation is in the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant. Refer to CO-8, "Inspection" .

Start and warm up the engine. Visually check if there is no leaks of engine coolant.

16. CHECK “A/F ALPHA-B1”
1. Start engine.
2. Select “A/F ALPHA-B1” in “DATA MONITOR (SPEC)” mode, and make sure that the indication is within
the SP value.
OK or NG
OK >>INSPECTION END
NG >> Detect malfunctioning part according to EC-92, "
Symptom Matrix Chart" .
17. CHECK “B/FUEL SCHDL”
Select “B/FUEL SCHDL” in “DATA MONITOR (SPEC)” mode, and
make sure that the indication is within the SP value.
OK or NG
OK >>INSPECTION END
NG (More than the SP value)>>GO TO 18.
NG (Less than the SP value)>>GO TO 25.
18. DETECT MALFUNCTIONING PART
1. Check for the cause of large engine friction. Refer to the following.
