WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure

engine coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a

quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

WATER PUMP

• Visually check for significant dirt or rust on the water pump body

and vane (A) and replace as necessary.

• Check that the vane shaft turns smoothly by hand and is not

excessively loose.

• Replace the water pump assembly if the water pump does not per-

form properly.

INSTALLATION

Installation is in the reverse order of removal.

• Tighten water pump bolts in order as shown.

CAUTION:

• Do not allow the water pump vane to contact any other parts.

• Water pump cannot be disassembled and must be replaced as

an assembly.

• Do not reuse gasket.

• Sealing surface must be clean and free of dents or flaws.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to

MA-11, "Fluids and Lubricants"

• Use procedure below to check for fuel leaks.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks

at connection points.

• Start engine. With engine speed increased, check again for fuel leaks at connection points.

• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leaks of fuel, exhaust gas, or any oils/fluids, including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels, including engine oil and engine coolant. Refill to spec-

ified level, if necessary.

• Summary of the inspection items:

*Power steering fluid, brake fluid, etc.
