Draining Coolant



Specific to:

Nissan Altima 2007-2008


CAUTION
Never remove the inverter cooling reservoir tank cap when the engine or inverter are hot. Serious burns could occur from high pressure coolant escaping from the inverter coolant reservoir tank.

  1. Wrap a thick cloth around the cap. Slowly push down and turn cap a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing down and turning it all the way.
  2.  
  3. Remove the inverter cooling reservoir tank cap (1).

Filling Coolant



Specific to:

Nissan Altima 2007-2008

  1. Slowly pour coolant into the inverter cooling reservoir tank (1) until the coolant level reaches MAX (A).

  2.  
  3. Turn ignition switch ON.
  4.  
  5. Select -INV WATER PUMP- in -ACTIVE TEST- mode with CONSULT-III, then operate the inverter cooling system coolant pump while continuing to fill the inverter cooling reservoir tank. Keep the coolant level between MIN (B) and MAX (A).
    WARNING
    Do not allow the coolant level in the reservoir tank to get too low when filling to avoid air being drawn into the Inverter cooling system.

  6.  
  7. When no air bubbles can be seen in the inverter cooling reservoir tank, fill the tank until the coolant level reaches MAX.
  8.  
  9. Install the inverter cooling reservoir tank cap (1) and inspect the system for leaks.

    1. CHECKING COOLANT LEVEL (INVERTER COOLING SYSTEM):
    2.  
    3. Check if the coolant level in the inverter cooling reservoir tank (1) is within MIN (B) to MAX (A) when coolant is cool.

    5. Adjust inverter cooling system coolant level as necessary.
    6.  

  2.  
  3. CHECKING COOLANT CONDITION (INVERTER COOLING SYSTEM):
    1. Check for excessive deposits of dirt or rust in the inverter cooling system coolant.
    2.  
    3. If the coolant contains excessive dirt or rust, replace the inverter cooling system coolant.
