BASIC INSPECTION Checking Engine Room

- Visually check engine room for smears*1 and leakage*2 of engine coolant when engine is cool.
  NOTE：
  - *1: Engine coolant does not drop.
  - *2: Engine coolant drop.

- Check engine assembly and cooling system for smears and leakage of engine coolant.
- Observe the clearance between the engine and radiator to check that there is no engine coolant collected on the front under cover.

Additional Inspection

- Check that engine coolant temperature history is not stored in ECM. Refer to CONSULT-III Function (GT-R certified NISSAN dealer).
- Perform this additional inspection after driving under conditions listed below:

- Higher-RPM (approaching redline) operation
- Frequent high pedal force braking from moderate and higher speeds
- Frequent throttle activation
- Fast revving throughout the RPM range

1.Remove front under cover. Refer to Exploded View.

2.Visually check the bottom of the engine for smears and leakage of engine coolant.

LEVEL

- Check that the reservoir tank engine coolant level is at the midpoint between the “MIN” (B) to “MAX” (A) with the engine cold.
  ■ CAUTION ■
  If engine coolant level exceeds the MAX line, leakage of engine coolant may occur during the rise in internal pressure in the engine coolant path. Therefore, thoroughly check that engine coolant level is below the MAX line.
- Adjust the engine coolant level if necessary.
- Check that the reservoir tank cap is tightened.

LEAKAGE
Engine Assembly

1.Visually check engine assembly and surround area for smears of engine coolant.

2.Wipe out smeared engine coolant using part cleaner or the equivalent.

3.Check again for engine coolant smears.

Radiator and Cooling System

- To check for leakage, apply pressure to the cooling system with the radiator cap tester and radiator cap tester adapter (commercial service tool) (A).

  Testing pressure | : Refer to Radiator.

  ■ WARNING ■
  Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from water outlet (front).
  ■ CAUTION ■
  Higher test pressure than that specified may cause radiator damage.
  NOTE：
  In a case that engine coolant decreases, fill radiator with engine coolant.
- If anything is found, repair or replace damaged parts.
