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 engine coolant.
Refer to LC-19, ªChanging Engine Coolantº.
2. Remove drive belts and idler pulley.
3. Loosen water pump pulley bolts.
4. Remove water pump pulley.
5. Remove front right wheel.
6. Remove front right undercover and front right fender protector.
7. Remove water pump bolts.
8. Remove water pump.
9. Reinstall parts in reverse order of removal.

CHECKING RADIATORNLLC0133S03Check radiator for mud or clogging. If necessary, clean radiator as
follows.
+Be careful not to bend or damage the radiator fins.
+When radiator is cleaned without removal, remove all sur-
rounding parts such as cooling fan, rediator shroud and horns.
Then tape the harness and connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core ver-
tically download.
2. Apply water again to all radiator core surfaces once per
minute.
3. Stop washing if any stains no longer flow out from the radia-
tor.
4. Blow air into the back side of radiator core vertically download.
+Use compressesd air lower than 490 kPa (5 kg/cm
2, 71 psi)
and keep distance more than 30 cm (11.8 in).
5. Blow air again into all the radiator core surfaces once per
minute until no water sprays out.
SLC613-A
CHECKING RADIATOR CAPNLLC0133S04To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78 - 98 kPa (0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Limit
59 - 98 kPa (0.6 - 1.0 kg/cm
2,9-14psi)

Pull the negative pressure valve to open it.
Check that it closes completely when released.
SLC266B
Water Pump
REMOVAL AND INSTALLATIONNLLC01271. 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. Refer to EM-86, ªChecking Drive Beltsº.
5. Remove RH engine mounting. Refer to EM-131, ªENGINE
REMOVALº.

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.
SLC433A
7. Use a scraper to remove liquid gasket from water pump.
+Also remove traces of liquid gasket from mating surface
of cylinder block.
SLC434AA
8. Apply a continuous bead of liquid gasket to mating surface of
water pump.
+Use Genuine Liquid Gasket or equivalent.
When filling radiator with coolant, refer to LC-38, ªChanging
Engine Coolantº.
When installing drive belts, refer to EM-86, ªChecking Drive
Beltsº.
9. Install any parts removed in reverse order of removal.
