Removal and Installation
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.
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, che ck 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.
