Coolant Draining and Refilling

COOLANT

Draining and Refilling


CAUTION:
- Do not reuse O-rings.
- Do not put additive such as waterleak preventive, since it may cause cooling waterway clogging.
- When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality mixed with water (distilled or demineralized).
DRAIN


CAUTION:
- Be sure to drain when coolant temperature is cold.
- This should be performed so that coolant does not come in contact with surrounding parts.


1.Remove Li-ion battery undercover, radiator drain plug (1) and degas tank cap and drain coolant.

2.Remove reservoir tank and drain the coolant as per the following procedure.
1.Remove radiator upper grille cover.
2.Remove reservoir tank hose and reservoir tank mounting bolts.
3.Pull out the lower reservoir tank toward vehicle front.
Remove the insertion area and raise the tank for removal.

REFILLING

1.Install reservoir tank. (Install in the reverse order of removal.)
2.Install radiator drain plug.

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


Tightening torque: Refer to "Exploded View" Exploded View.
3.Check tightening of hose clamp.





4.Remove bleeder plug (1) of the on board charger.





5.Fill coolant to line (A) from the degas tank cap.





6.Remove the hose joint (1) at the traction motor inverter front and bleed air. Check coolant flow visually and reconnect the hose.





7.Fill coolant to line (A) from the degas tank cap.
8.Close the bleeder plug of the on board charger and close the degas tank cap.
9.Set the vehicle to READY and operate the electric water pump.





10.When the degas tank level is low, open the degas tank cap and refill the tank with coolant to line (A).
11.When the level is not lowered, close the degas tank cap and turn OFF the power switch (stop the electric water pump).
NOTE:
If the electric water pump is stopped with the degas tank open, coolant may be spilled.
12.Refill coolant to "MAX" line of reservoir tank.

CHECK WATER FLOW SOUND


CAUTION:
Prior to check, be sure to close windows, doors, and hood, and turn off audio system and other electrical loads.
1.Set the vehicle to READY and operate the electric water pump.
2.Operate the electric water pump for 1 minute.
3.Check if water flow sound can be heard from the back of the compartment (near the on board charger).
4.If water flow sound is heard, operate the electric water pump until it cannot be heard.
5.When water flow sound cannot be heard, fill the reservoir tank up to "MAX" line.

CAUTION:
- Insufficient coolant may cause low power or stop of vehicle due to insufficient cooling of the traction motor inverter. Be sure to bleed air thoroughly.
- Never operate the electric water pump without coolant.
