• Check valve seat (A) of radiator cap.
- Replace the cap if the metal plunger cannot be seen around the
edge of the black rubber gasket.
- Replace the cap if deposits of waxy residue or other foreign mate- rial are on the black rubber gasket or the metal retainer.
NOTE:
Thoroughly wipe out the radiator filler neck to remove any waxy
residue or foreign material.
• Pull negative-pressure valve to open it, and check that it closes completely when released.
- Check that there is no dirt or damage on the valve seat of radiator cap negative-pressure valve.
- Check that there are no abnormalities in the opening and closing conditions of negative-pressure valve.
• Check radiator cap relief pressure using suitable tools (A) and (B).
- When connecting the radiator cap to suitable tool (B), apply water or engine coolant to the cap seal surface.
- Replace the radiator cap if ther e is an abnormality in the negative-
pressure valve, or if the open-valve pressure is outside of the stan-
dard values.

RADIATOR : InspectionINFOID:0000000012432138
Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
• Be careful not to bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts in order to access the radia-
tor core. Then tape harness and harness conn ectors to prevent water from entering.
1. Spray water to the back side of the radiator co re using a side to side motion from the top down.
2. Stop spraying when debris no longer flows from radiator.
3. Blow air into the back side of radiator core using side to side motion from the top down. • Use compressed air lower than 490 kPa (5 kg/cm
2, 71 psi) and keep distance more than 30 cm (11.81
in).
4. Continue to blow air until no water sprays out.
5. Check for engine coolant leaks. Repair if necessary.

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.

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.
