SERVICE INFORMATION

If for any reason the vehicle's cooling system needs to be filled with coolant due to a service repair or maintenance, use the Coolant Refill Tool #J-45695.

Using this tool properly will ensure complete filling without trapped air bubbles in the cooling system.
Air pockets in the cooling system can cause:
1. Overheating
2. Poor heater performance
3. Gurgling noise from the heater core

To ensure the tool is used correctly, refer to the Operating Instructions supplied with the tool and the Service Procedure in this Bulletin.

Refer to the "Essential Tool Shipment" flyer (see Fig 2 ) for additional information.

This special tool is "Essential" and was automatically sent to all Nissan dealers.

Additional tools can be ordered from Tech-Mate.

SERVICE PROCEDURE

Refer to the Operating Instructions supplied with the tool for complete refill procedure.

Key points to ensure the cooling system is purged of air bubbles are as follows:

Always start with an Empty Radiator.

For step 2 of the Operating Instructions:

To hold the coolant mixture supply, use a clean bucket or other suitable container that is larger than the cooling system's total capacity.
The amount of coolant mixture in the refill supply must be more than needed to fill the system completely.
This will help avoid pulling in air at the end of the refilling procedure.
NOTE:
- See the appropriate Service Manual for cooling system refill capacity.
- Use Genuine NISSAN Anti-freeze Coolant or equivalent, mixed 50/50 with distilled water or demineralized water.

For step 3 of the Operating Instructions:

Make sure to Purge all air from the Refill Tube (intake hose) before beginning the refill process.
NOTE: The Venturi will NOT be harmed if some coolant goes through it during the air purge process.
Place the container of coolant mixture above the level of the radiator during the refill process.
