2. Start engine and let it idle.
3. Listen for an intake air leak after the mass air flow sensor.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace error-detected parts.
2.CHECK EXHAUST GAS LEAK
1. Stop engine and visually check exhaust tube, three way catalyst and muffler for dents connection.
2. Start engine and let it idle.
3. Listen for an exhaust gas leak before three way catalyst (manifold).

INSPECTION AFTER REMOVAL
• 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 asan 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, includi ng 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 lea ks 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.

INFOID:0000000012432149
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radi ator. Wrap a thick cloth around the radiator cap. Slowly turn it a
quarter of a turn to release built-up pressure. Carefu lly 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.
REMOVAL
1. Drain engine coolant. Refer to CO-8, "Draining Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove air ducts and air cleaner assembly. Refer to EM-26, "
Removal and Installation".
3. Disconnect radiator hose (upper). Refer to CO-13, "
Exploded View".
4. Disconnect harness connector from engine coolant temperature sensor.
5. Disconnect harness connector from cylinder block heater (Canada only).
6. Disconnect water hoses and heater hoses from water outlet.
7. Remove water outlet.
8. Remove engine coolant temperature sens or from water outlet, if necessary.
9. Remove cylinder block heater from water outlet, if necessary (Canada only).
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not reuse gasket.

ENGINE OIL LEVEL
NOTE:
Before starting engine, position the vehicle so that it
is level and check the engine oil level. If engine is already
started, stop it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check that the engine oil level is within the range (A) as shown.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.
ENGINE OIL LEAKS
Check for engine oil leaks around the following areas:
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Oil level sensor
• Engine oil temperature sensor
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Mating surface between front cover and rocker cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seals (front and rear)
• Front cover
ENGINE OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• When checking engine oil pressure, sh ift selector should be in the "P" (Park) or "N" (Neutral) posi-
tion, and apply parking brake securely.
1. Check engine oil level.
