REMOVAL ■ WARNING ■ Never remove radiator cap and reservoir tank cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove cap by turning it all the way.

1.Drain engine coolant from radiator. Refer to Draining.
■ CAUTION ■

- Perform this step when the engine is cold.
- Never spill engine coolant on drive belt.

2.Remove air cleaner case (RH and LH). Refer to Exploded View.

3.Remove air intake duct assembly 1 with charge air cooler. Refer to Exploded View (GT-R certified NISSAN dealer).

4.Remove condenser. Refer to Exploded View (GT-R certified NISSAN dealer).

5.Remove reservoir tank if necessary.

6.Remove radiator hoses (upper and lower) and reservoir tank hose.

7.Support the hood with a proper tool to prevent the hood from falling.
■ CAUTION ■
Check that the tool surely supports the hood so as not to accidentally fall down during the work.

8.Remove hood support rod and hood lock bracket assembly. Refer to Exploded View and Exploded View (GT-R certified NISSAN dealer).

9.Rotate two radiator upper mount brackets 90 degrees in direction as shown in the figure, and remove them.

1 | : Radiator upper mount bracket
A | : Turn 90° counterclockwise

10.Remove radiator as follows:
■ CAUTION ■
Be careful not to damage radiator core.

(1)Lift up and pull the radiator (1) forward, and then remove the mounting rubber (lower) (3) from the radiator core support (2).

(2)Remove radiator (1) from front of radiator core support (2).

| : Vehicle front

INSTALLATION
Note the following, and install in the reverse order of removal.
■ CAUTION ■

- Replace water hose clamp if it is removed.
- Use genuine mounting bolts for the cooling fan assembly and strictly observe the tightening torque. (Breakage prevention for radiator)

NOTE：

- Insert the radiator hose (1) all the way to the stopper (2) or by 33mm (hose without a stopper)

  Unit mm (in)
  A. | Radiator side | B. | Engine side |  |

- For the orientation of the hose clamp pawl, refer to the figure.

  Radiator hose | Hose end | Paint mark | Position of hose clamp*
  Radiator hose (upper) | Radiator side | Upper | A
  Engine side | Upper | A
  Radiator hose (lower) | Radiator side | Lower | C
  Engine side | Right side | B
  *Refer to the illustrations for the specific position each hose clamp tab.

  a. | 45° |  |  |  |
  | Vehicle upper |  |  |  |

- The angle (a) created by the hose clamp pawl and the specified line (A) must be within ±30° as shown in the figure.
- To install hose clamps (1), check that the dimension (A) from the end of the paint mark (2) on the radiator hose to the hose clamp is within the reference value.

  Dimension “A” | (−1) – (+1)mm
