Water Pump
REMOVAL AND INSTALLATION
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.
1. Remove radiator lower hose from radiator and drain engine
coolant.
2. Drain engine coolant from cylinder block.
3. Remove upper radiator hose, timing belt covers, front engine
mounting bracket and timing belt. (Refer to EM section).
4. Remove timing belt tensioner and idler and timing belt lower
back cover.
5. Remove water pump.

When installing water pump, replace the gasket with a new
one.
INSPECTION

Check body assembly for rust or corrosion.

Check for rough operation due to excessive end play.

REMOVAL AND INSTALLATION
1. Drain engine coolant.
2. Remove lower radiator hose.
3. Remove water inlet, then take out thermostat.
4. Before installing thermostat, remove all traces of liquid gasket
from mating surface of each part using a scraper.
5. Apply liquid gasket to water outlet, thermostat housing and
water inlet.
6. Install thermostat with jiggle valve uppermost.

After installation, run engine for a few minutes, and check
for leaks.

INSPECTION
1. Check valve seating condition at ordinary temperatures. It
should seat tightly.
2. Check valve opening temperature and valve lift.
Valve opening temperature°C(°F) 82 (180)
Valve lift mm/°C (in/°F)More than 10/95 (0.39/203)
3. Then check if valve closes at 5°C (41°F) below valve opening
temperature.
