Removal and InstallationNBS004RQ
CAUTION:
When removing water pump, be careful not to get engine coolant on drive belts.
Water pump can not be disassembled and should be replaced as a unit.
After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter [SST: EG17650301 (J33984-
A)].
REMOVAL
1. Remove following parts:
Front engine undercover (power tool)
Engine cover: Refer to EM-179, "INTAKE MANIFOLD" .
Engine room cover (RH and LH): Refer to EM-173, "ENGINE ROOM COVER" .
Air duct (inlet): Refer to EM-177, "AIR CLEANER AND AIR DUCT" .
Alternator, water pump and A/C compressor belt: Refer to EM-174, "DRIVE BELTS" .
2. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-40, "
Chang-
ing Engine Coolant" and EM-250, "DISASSEMBLY" .
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belts.
3. Remove water pump pulley.
4. Remove water pump.
Engine coolant will leak from cylinder block, so have a receptacle ready under vehicle.

System DescriptionNKS003TV
UNIFIED METER CONTROL UNIT
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.
Digital meter is adopted for odo/trip meter.
NOTE:
The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
Dot matrix LCD is adopted to display “push engine starter”, “A/T position” and “ICC system* ”.
Odo/trip meter and dot matrix LCD segments can be checked in self-diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
*: With ICC system
