REMOVAL
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.
