2. Separate the hose clamp (1) and heater hose (2) at the

position shown in the figure (

), and hold the end of the

hose at the same height.

3. Fill with coolant at a speed of 3 L/min or less (like pouring

water with a kettle) until it fills the radiator cap (1) neck.

If coolant comes out from the heater hose when filling with

coolant, connect the heater hose and continue filling with

coolant.

CAUTION:

•

Filling with coolant at a high speed may allow air to

mix with coolant. Be sure to fill with coolant slowly,

observing the above speed.

•

Never spill coolant on any electrical equipment (such

as the alternator) during the operation.

When not using CONSULT

1. Separate the hose clamp (1) and heater hose (2) at the

position as shown in the figure (

), and hold the end of the

hose at the same height.

2. Fill with coolant at a speed of 3 L/min or less (like pouring

water with a kettle) until it fills the radiator cap (1) neck.

If coolant comes out from the heater hose while adding

coolant, connect the heater hose and continue adding cool-

ant.

CAUTION:

•

Filling with coolant at a high speed may allow air to

mix with coolant. Be sure to fill with coolant slowly,

observing the above speed.

•

Never spill coolant on any electrical equipment (such

as the alternator) during the operation.

6. Fill with coolant to "MAX" line of reservoir tank.

7. Install the cowl top extension. Refer to

EXT-30, "Removal and Installation"

8. Install the radiator cap.
9. Perform the following operation for warming up the engine.

When using CONSULT

1. Start the engine, and set the heater control temperature to "FULL HOT".

2. Use CONSULT “WORK SUPPORT” mode to perform “ENGINE COOLANT BYPASS VALVE”. Refer

EC-667, "CONSULT Function"

NOTE:

CONSULT can be used to open the bypass valve on the multi-way control valve.

Check that there is no coolant leakage from the drain plug and heater hose connections.

When not using CONSULT

1. Start the engine and set the heater control temperature to "FULL HOT".

2. Warm up the engine until the bypass valve on the multi-way control valve opens. The warm-up time

should be approximately 10 minutes at 3,000 rpm.

Check that the bypass valve on the multi-way control valve is open by touching the radiator hose

(lower) with a hand and checking that warm water is flowing.

CAUTION:

Be careful that coolant does not overheat.

Check that there is no coolant leakage from the drain plug and heater hose connections.

10. Stop the engine.
11. When the engine is cold (approximately 50

°C or less), remove the radiator cap and check the coolant

level. If the level is low, fill with coolant again until it fills the radiator cap neck, and then repeat operation

from step 7.

CAUTION:

Never spill coolant on any electrical equipment (such as the alternator) during the operation.

12. When the coolant level stabilizes, fill with coolant up to the "MAX" line of reservoir tank.

CHECK WATER FLOW SOUND

CAUTION:

Prior to check, be sure to close windows, doors, and hood, and turn off radio and other electrical

loads.
1. Allow the engine to cool (to approximately 50

°C or less).

2. Set the temperature of the heater control to "FULL HOT".
3. Start engine. Perform the following cycle three times. Keep the engine speed at 1,000 rpm for approxi-

mately 30 seconds and then increase it gradually to 3,000 rpm.

4. During the operation described above in step 3, check for water flow sound from heater core.
5. If water flow sounds are heard, fill with coolant to the radiator cap neck at a speed of 3 L/min or less (like

pouring water with a kettle), and then repeat the operations from step 7 of "Filling Engine Coolant" to step

4 of "How to Check Water Flow Sound".

CAUTION:

• Filling with coolant at a high speed may allow air to mix with coolant. Be sure to fill with coolant

slowly, observing the speed specified above.

• Never spill coolant on any electrical equipment (such as the alternator) during the operation.

ENGINE MAINTENANCE (MR EXCEPT FOR NISMO RS MODELS)

ENGINE COOLANT : Flushing

INFOID:0000000012200203

1. Install radiator drain plug.

CAUTION:

Be sure to clean drain plug and install with new O-ring.

• If water drain plugs on cylinder block are removed, close and tighten them. Refer to

EM-72, "Setting"

2. Remove air duct (suction side), air cleaner cover assembly and air cleaner body assembly. Refer to

EM-

27, "Exploded View"

3. Disconnect vacuum hose break booster side, and remove vacuum tube from clamp.
4. Disconnect heater hose (1) at position (

) in the figure.

• Enhance heater as high as possible.

5. Fill radiator and reservoir tank with water and reinstall radiator cap.

• When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the

engine coolant.

6. Connect vacuum hose, and install vacuum tube.
7. Install air duct (suction side), air cleaner cover assembly and air cleaner body assembly. Refer to

EM-27,

"Exploded View"

8. Run the engine and warm it up to normal operating temperature.
9. Rev the engine two or three times under no-load.
10. Stop the engine and wait until it cools down.
11. Drain water from the system. Refer to

MA-26, "ENGINE COOLANT : Draining and Filling"

12. Repeat steps 1 through 9 until clear water begins to drain from radiator.

• Visually check valve seat of the radiator cap vacuum valve for dirt and damage.

CAUTION:

Check valve seat (A) visually in vertical position. If the valve

seat is excessively extended so that lower metal plunger (B) is

not visible, replace the radiator cap.

• Move the vacuum valve and check for smooth opening and clos-

ing.

• Connect radiator cap tester (commercial service tool) (A) and
