LEVEL
• Check that the reservoir tank engine coolant level is within the
“MIN” to “MAX” when the engine is cool.
• Adjust the engine coolant level if necessary.
CAUTION:
Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent in its quality mixed with water (distilled or deminer-
alized). Refer to
MA-11, "Fluids and Lubricants"
LEAKAGE
• To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and the radiator
cap tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
may occur from high-pressure engine coolant escaping from
engine cooling system.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
If a case that engine coolant decreases, replenish radiator with engine coolant.
• If anything is found, repair or replace damaged parts.
Draining and Filling
INFOID:0000000012197555
CAUTION:
• Never apply additive agent like anti-leakage sealant. Doing so may cause coolant passage clog.
• When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality
mixed with water (distilled or demineralized). Refer to
MA-11, "Fluids and Lubricants"
• Never dilute using water.
DRAINING
WARNING:
Never open the radiator cap or drain plug when the engine is hot. Hot liquid may spray out, causing
serious injury.
CAUTION:
• Never spill coolant on the drive belt while working.
• Be sure to perform this operation when coolant temperature is cold.
1. Turn the ignition switch ON, wait for 10 seconds or more, and then turn it OFF again.
2. Connect drain hose.

• Use a general-purpose hose with the dimensions show in the
figure.
3. Open radiator drain plug (A) at the bottom of radiator, and then
remove radiator cap.
CAUTION:
Perform this step when engine is cold.
• When draining all of engine coolant in the system, open water
drain plugs on cylinder block. Refer to
4. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to
.
6. Disconnect drain hose.
REFILLING
1. Install reservoir tank. Refer to
2. Install the radiator drain plug.
• Replace the drain plug O-ring with a new one.
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
3. Check that each hose clamp is firmly tightened.
4. Remove the cowl top extension. Refer to
EXT-30, "Removal and Installation"
5. Perform the following procedure for draining the air from piping.
If using CONSULT
1. Turn the ignition switch ON again and use CONSULT “WORK SUPPORT” mode to perform “ENGINE
COOLANT BYPASS VALVE”. Refer to
.
CAUTION:
Never start engine.
NOTE:
CONSULT can be used to open the bypass valve on the multi-way control valve.

ENGINE COOLANT
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.
