• Do not use SST to crimp the circled areas
indicated in the illustration. Use pliers and be
careful not to damage the core plates.
(f) Check the lock plate height A after completing the
crimping.
Standard plate height A:
8.8 mm (0.347 in.)
If the height is not as specified, readjust the stopper
bolt of the handle and crimp the lock plate again.
2. INSTALL UPPER RADIATOR TANK
HINT:
The installation procedure for the upper radiator tank is
the same as that for the lower radiator tank.
3. INSTALL DRAIN PLUG
(a) Install a new O-ring to the drain plug.
(b) Install a new O-ring to the air drain plug.
(c) Install the drain plug and air drain plug.
4. INSPECT FOR WATER LEAK
(a) Plug the inlet and outlet pipes of the radiator with
SST.
SST 09230-01010 (09231-00030, 09231-00060)
(b) Using a radiator cap tester, apply pressure to the
radiator.
Standard test pressure:
177 kPa (1.8 kgf/cm
2, 26 psi)
(c) Submerge the radiator in water.
(d) Inspect for leak.
HINT:
On radiators with resin tanks, there is clearance
between the tank and lock plate where a minute
amount of air will remain, giving the appearance of
an air leak when the radiator is submerged in water.
Therefore, before doing the water leak test, first
swish the radiator around in the water until all air
bubbles disappear.

9. REMOVE WATER INLET HOUSING
(a) Disconnect the water hose.
(b) Remove the 2 bolts, nut and water inlet housing.
(c) Remove the water inlet housing gasket and water
outlet pipe O-ring.
10. REMOVE WATER PUMP ASSEMBLY
(a) Remove the 16 bolts, water pump assembly and
water pump gasket.
INSPECTION
1. INSPECT WATER PUMP ASSEMBLY
(a) Visually check the drain hole and air hole for coolant
leakage.
(b) Turn the pulley, and check that the water pump
bearing moves smoothly and noiselessly.
If the bearing does not move smoothly and
noiselessly, replace the water pump.
