Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Coolant: Refilling
- 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). Refer to Fluids and Lubricants .
- 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.
: 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.
: Vehicle front
- Remove air relief plug (1) on heater hose side.
: Vehicle front
- Fill up the radiator with cooling water.
Pour engine coolant through engine coolant filler neck slowly of less than 2
(2-1/8 US qt, 1-3/4 lmp qt) a minute to allow air in system to escape.
Engine coolant capacity
: Refer to Periodical Maintenance Specification .
(With reservoir tank at "MAX" level)

- When engine coolant overflows air relief hole on radiator, install air relief plug with new O-ring.
: 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.
: 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 deg.C (122 deg.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.
- Allow the engine to become cold (approximately 50 deg.C or less).
- 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.
- Check that flow noise can be heard from the heater core during the Step b operation.
- If flow noise can be heard, repeat from Step 12 of Refilling to Step c of Flow Noise Verification Method.
- Check that the reservoir tank cap is tightened.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
