Engine Coolant: Refilling

WARNING: This page is about a different car, the 2013 Infiniti M56. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Do not put additive such as waterlog 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). Refer to "FOR NORTH AMERICA: FLUIDS AND LUBRICANTS " (FOR NORTH AMERICA), "FOR MEXICO: FLUIDS AND LUBRICANTS " (FOR MEXICO).

Remove air cleaner case (LH) and air duct (inlet). Refer to "EXPLODED VIEW ".
Install reservoir tank if removed, and radiator drain plug.
CAUTION: Be sure to clean drain plug and install with new O-ring.

Torque: 1.2 N.m (0.12 kg-m, 11 in-lb)

If water drain plug on cylinder block is removed, close and tighten it. Refer to "DISASSEMBLY AND ASSEMBLY ".
Check that each hose clamp is firmly tightened.
Remove air relief plug (1) on radiator left side.

Fill up the radiator with cooling water.
Pour engine coolant through engine coolant filler neck slowly of less than 2 l (2-1/8 US qt, 1-3/4 lmp qt) a minute to allow air in system to escape.

Engine coolant capacity (With reservoir tank at "MAX" level): Refer to " PERIODICAL MAINTENANCE SPECIFICATION ".

When engine coolant overflows air relief hole on radiator, install air relief plug with new O-ring.
Torque: 1.2 N.m (0.12 kg-m, 11 in-lb)
Refill reservoir tank to "MAX" level line with engine coolant.
When engine coolant overflows air relief hole on heater hose, install air relief plug with new O-ring. Then refill radiator with engine coolant.
CAUTION: Do not reuse O-rings.

Torque: 1.2 N.m (0.12 kg-m, 11 in-lb)
Install air cleaner case (LH) and air duct (inlet).
Install radiator cap.
Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3, 000 rpm.
- Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION: Watch water temperature gauge so as not to overheat engine.
Stop the engine and cool down to less than approximately 50°C (122°F).
- Cool down using fan to reduce the time.
- If necessary, refill radiator up to filler neck with engine coolant.
- Remove the radiator cap to check the fluid level. If the fluid level is low, refill with cooling water and repeat the steps from Step 8.
Refill reservoir tank to "MAX" level line with engine coolant.
Check cooling system for leakage with engine running.
Check flow noise, according to the following steps.
CAUTION: To check flow noise, turn OFF the radio and close the windows, doors, and the hood.
1. Allow the engine to become cold (approximately 50°C or less).
2. Start the engine, maintain 1000 rpm for approximately 30 seconds, and increase the engine speed from 1000 to 3000 rpm. Repeat this cycle three times.
3. Check that flow noise can be heard from the heater core during the Step b operation.
4. If flow noise can be heard, repeat from Step 12 of Refilling to Step c of Flow Noise Verification Method.
5. Check that the reservoir tank cap is tightened.
