CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING PROCEDURE
Refer to GI-34, "CONSULT-II Start Procedure" .
Diagnostic test mode Function Reference
WORK SUPPORTThis mode enables a technician to adjust some devices faster and more accu-
rately by following the indications on CONSULT-II.BRC-40, "
Adjustment of

WATER PUMP

WATE R P U M PPFP:21020
Removal and InstallationBBS004X6
CAUTION:

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

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 (commercial service tool) and radiator cap tester adapter [SST: EG17650301].
REMOVAL
1. Remove engine cover. Refer to EM-133, "INTAKE MANIFOLD COLLECTOR" .
2. Remove air duct (inlet). Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
3. Remove undercover and splash guard (RH).
4. Drain engine coolant from radiator. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
5. Remove drive belts. Refer to EM-128, "
DRIVE BELTS" .
6. Remove reservoir tank of radiator. Refer to CO-37, "
RADIATOR" .
7. Remove reservoir tank of power steering oil pump with piping connected, and move it to aside.
8. Support oil pan (lower) bottom with transmission jack.
9. Remove engine mounting insulator (RH) and engine mounting bracket (RH). Refer to EM-223, "
ENGINE
ASSEMBLY" .
1. Water pump 2. Timing chain tensioner (primary) 3. Chain tensioner cover
4. Water drain plug (front) 5. Water pump cover 6. O-ring

10. Remove water drain plug (front) on water pump side of cylinder
block to drain engine coolant from engine inside.
11. Remove chain tensioner cover and water pump cover from front timing chain case.

12. Remove idler pulley and bracket. Refer to EM-173, "
TIMING CHAIN" .
13. Remove timing chain tensioner (primary) as follows:
a. Remove lower mounting bolt.
b. Loosen upper mounting bolt slowly, and then turn timing chain
tensioner (primary) on the mounting bolt so that plunger is fully
expanded.
NOTE:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c. Remove upper mounting bolt, and then remove timing chain ten-
sioner (primary).
CAUTION:
Be careful not to drop mounting bolts inside timing chain
case.
14. Remove water pump as follows:
a. Remove three water pump mounting bolts. Secure a gap
between water pump gear and timing chain, by turning crank-
shaft pulley counterclockwise until timing chain looseness on
water pump sprocket becomes maximum.
b. Screw M8 bolts [pitch: 1.25 mm (0.049 in) length: Approx. 50
mm (1.97 in)] into water pumps upper and lower mounting bolt
holes until they reach timing chain case. Then, alternately
tighten each bolt for a half turn, and pull out water pump.
CAUTION:

Pull straight out while preventing vane from contacting
socket in installation area.

Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump.
CAUTION:
Do not disassemble water pump.
INSPECTION AFTER REMOVAL

Check for badly rusted or corroded water pump body assembly.
