RADIATOR
●Check radiator cap relief pressure.
●When connecting the radiator cap to the tester, apply engine
coolant to the cap seal part.
●Replace the radiator cap if there is an unusualness in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
Checking RadiatorEBS00BRH
Check 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 surrounding parts such as cooling fan, radiator
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 vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
●Use compressed air lower than 490 kPa (4.9 bar 5 kg/cm2 , 71psi) and keep distance more than 30
cm(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out. Standard : 78 - 98 kPa (0.78 - 0.98 bar, 0.8 - 1.0 kg/
cm
2 , 11 - 14 psi)
Limit : 59 kPa (0.59 bar, 0.6 kg/cm
2 , 9 psi)

Removal and InstallationEBS00BB4
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator.
REMOVAL
1. Remove the under cover, splash cover (right), and drive belt.
2. Drain engine coolant. Refer to CO-29, "
DRAINING ENGINE COOLANT" .
CAUTION:
Perform when the engine is cold.
3. Support the bottom of the oil pan with a floor jack etc, and remove the right engine mount bracket (front
side of the engine).
4. Remove the water pump pulley.
●Loosen the pulley bolts after fixing the pulley using a screwdriver etc.
5. Remove engine mount bracket.
6. Remove the water pump.
●Engine coolant will leak from the cylinder block, so have a receptacle ready below.
CAUTION:
●Handle the water pump vane so that it does not contact any other parts.
●Water pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL
●Visually check that there is no significant dirt or rusting on the
water pump body and vane.
●Check that there is no looseness in the vane shaft, and that it
turns smoothly when rotated by hand.
●If there are any unusualness, replace the water pump assembly.

WATER PUMP
INSTALLATION
●Install in the reverse order of removal
●Install the water pump pulley with the front mark (painted white, used to prevent errors during assembly)
facing the front of the engine. Refer to the figure above.
INSPECTION AFTER INSTALLATION
Check for engine coolant leaks using radiator cap tester. Refer to CO-29, "CHECKING RADIATOR SYSTEM
FOR LEAKS" .
