Removal and Installation

WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from highpressure engine coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release builtup 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 spilling.

REMOVAL

1. Drain 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.
3. Remove battery wedge bracket.
4. Disconnect radiator hose (upper).
5. Disconnect harness connector from engine coolant temperature sensor.
6. Disconnect harness connector from cylinder block heater (Canada only).
7. Disconnect water hoses and heater hoses from water outlet.
8. Remove water outlet.
9. Remove engine coolant temperature sensor from water outlet, if necessary.
10. Remove cylinder block heater from water outlet, if necessary (Canada only).

INSTALLATION

Installation is in the reverse order of removal.

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.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
• Start engine. With engine speed increased, check again for fuel leakage 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 leakage 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 specified level, if necessary.
• Summary of the inspection items:
