ComponentINFOID:0000000001325882
Removal and InstallationINFOID:0000000001325883
CAUTION:
 When removing water pump, be careful no
t 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 (commercial service tool).
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-37, "Chang-
ing Engine Coolant" and EM-242, "Disassembly and Assembly".
CAUTION:
 Perform this step when engine is cold.
 Do not spill engine coolant on drive belts.
2. Remove following parts:  Engine front undercover
 Air duct (inlet): Refer to EM-173, "
Component".
 Alternator, water pump and A/C compressor belt: Refer to EM-170, "
Component".
3. Remove fan coupling with cooling fan, and then fan and water pump pulley.
4. Remove water pump.  Engine coolant will leak from cylinder block, so have a receptacle ready under vehicle.
CAUTION:
 Handle the water pump vane so that it does not contact any other parts.
 Do not disassemble water pump.

DRIVE BELTS

Checking Drive BeltsINFOID:0000000001429496
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying,
wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway between pulleys.
 Inspection should be done only when engine is cold, or over30 minutes after engine is stopped.
 Measure the belt tension with belt tension gauge (Commercial service tool: BT3373-F or equivalent) (A) at points marked
shown in the figure.
 When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
 Adjust if the belt deflection exc eeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:
• When checking the belt deflect ion or the tension immedi-
ately after installation, first ad just it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust
to the specified value to avo id variation in deflection
between pulleys.
 Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

 When belt is replaced with a new one, adjust it
to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
 When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
 When checking belt deflection or tension immediately af ter installation, first adjust it to the specified
value. Then, after turning crankshaft two turns or mo re, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.
 When installing belt, make sure that it is correctly engaged with pulley grooves.
 Keep engine oil, working fl uid and engine coolant away from belt and pulley grooves.
 Do not twist or bend belt excessively.
