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.

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.

Low Temperature Protection Control
• When thermo control amp. detects
that evaporator fin temperature
is 1.5° C (35° F) or less, thermo control amp. switches A/C ON sig-
nal to OFF and stops the compressor.
When the evaporator fin temperature returns to 3 °C (37° F) or
more, the compressor is activated.
CONTROL BY ECM
Refrigerant Pressure Protection
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure s\
en-
sor, located on the liquid tank on the condenser. The refr igerant pressure sensor detects the pressure inside
the refrigerant line and sends a voltage signal to the ECM. If the system pressure rises above or falls below
the following values, the ECM requests the IPDM E/ R to de-energize the A/C relay and disengage the com-
pressor.
• 3.12 MPa (31.82 kg/cm
2, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)
• 2.74 MPa (27.95 kg/cm
2, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)
• 0.14 MPa (1.43 kg/cm
2, 20.3 psi) or less
Compressor Oil Cir culation Control
When the engine starts while the engine coolant temperature is 56 °C (133° F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor oil once.
Air Conditioning Cut Control
When the engine is under a high load condition, the ECM transmits an A/C relay OFF request to IPDM E/R,
and stops the compressor. Refer to EC-37, "
AIR CONDITIONING CUT CONTROL : System Description".

DescriptionINFOID:0000000012430752
Symptom
• Insufficient heating
• No warm air comes out. (Air flow volume is normal.)
Diagnosis ProcedureINFOID:0000000012430753
NOTE:
Perform self-diagnosis with CONSULT before performing sy mptom diagnosis. If any malfunction result or DTC
is detected, perform the corresponding diagnosis.
1.CHECK COOLING SYSTEM
1. Check engine coolant level and check for leakage. Refer to CO-8, "
Inspection".
2. Check radiator cap. Refer to CO-12, "
RADIATOR CAP : Inspection".
3. Check water flow sounds of the engine coolant. Refer to CO-9, "
Refilling".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refill engine coolant and repair or replace the parts depending on the inspection results.
2.CHECK HEATER HOSE
Check installation of heater hose by visually or touching.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace parts depending on the inspection results.
3.CHECK HEATER CORE
1. Check temperature of inlet hose and outlet hose of heater core.
2. Check that inlet side of heater core is hot and the outle t side is slightly lower than/almost equal to the inlet
side.
CAUTION:
Always perform the temperature inspection in a sh ort period of time because the engine coolant
temperature is very hot.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace heater core. Refer to HA-35, "
HEATER CORE : Removal and Installation".
4.CHECK AIR LEAKAGE FROM EACH DUCT
Check duct and nozzle, etc. of air conditioning system for air leakage.
Is the inspection result normal?
YES >> Check air mix door cable inst allation and air mix door operation.
NO >> Repair or replace parts depending on the inspection results.
