WARNING:
ISituate vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled down.
IFor safety during subsequent steps, the tension of wires
should be slackened against the engine.
IBefore removing front axle from transaxle, place safety
stands under designated front supporting points. Refer to
GI section for lifting points and towing.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG
or Eurofast.
CAUTION:
IWhen lifting engine, be careful not to strike adjacent parts,
especially accelerator wire casing, brake lines, and brake
master cylinder.
IAlways use engine slingers when hoisting the engine.
IWhen removing drive shaft, be careful not to damage tran-
saxle oil seal.
1. Remove engine undercovers and splash covers.
2. Remove front exhaust tube.
3. Disconnect lower water hose from radiator and drain coolant.
4. Drain transaxle oil.
5. Remove power steering mounting bolt. (See left.)
6. Drain coolant from cylinder head.
7. Disconnect water hoses and electrical wiring from radiator and
remove radiator.
8. Disconnect fuel tubes and vacuum tubes.
9. Release power steering belt adjusting nut and remove power
steering pump from engine.
Bind pump properly to the vehicle.
10. Remove A/C compressor.
11. Disconnect or remove electrical wiring where necessary.
12. Release clutch lever cable.
13. Release tachometer cable from transaxle housing.
14. Remove front wheels.
15. Remove brake caliper mounting bolts and bind caliper properly
to vehicle LH & RH.

System CheckNCLC0017WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure fluid escaping from the
radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.

REMOVAL AND INSTALLATIONNCLC0018
CAUTION:

When removing water pump assembly, be careful not to
get coolant on drive belt.

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

After installing water pump, and check for leaks using
radiator cap tester.
1. Drain coolant from radiator and cylinder block.
Refer to MA section (“Changing Engine Coolant”,“ENGINE
MAINTENANCE”).
2. Remove cylinder head front mounting bracket.
3. Remove drive belts and idler pulley.
4. Loosen water pump pulley bolts.
5. Remove water pump pulley.
6. Remove water pump bolts.
7. Remove water pump with gasket.
8. Reinstall parts in reverse order of removal.

Pull the negative pressure valve to open it.
Check that it closes completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.

REMOVAL AND INSTALLATION
1. Drain coolant from radiator.
2. Remove cylinder block drain plug located at left front of cylin-
der block and drain coolant.
3. Remove front RH wheel and engine side cover.
4. Remove drive belts.
5. Remove front engine mounting.
6. Remove water pump.
CAUTION:

When removing water pump assembly, be careful not to
get coolant on drive belt.

Water pump cannot 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.
7. Before installing, remove all traces of liquid gasket from mat-
ing surface of water pump using a scraper.

Also remove traces of liquid gasket from mating surface
of cylinder block.
