Time:
Varies depending on your equipment and experience. Expect more than 20 hours in full
removal and reinstallation the first time you perform the job.
Difficulty:
Moderate-Difficult
Description:
This process outlines the installation steps required for removal and reinstallation of the
GT-R's VR38DETT engine assembly. This guide outlines the steps that are taken if you
remove the radiator core support when removing the engine. This is not required, but in
this particular situation we had to remove it anyway for some other work we did,
therefore we included the steps here. You can simply drop the engine out of the bottom
of the car without removing the support/etc.

Preparation:
Disconnect the battery.
Raise and secure vehicle off the ground. A lift is obviously suggested, but not required.
Allow the vehicle to sit at least one hour to allow it to cool.
Step-by-step procedure:
1. Remove the intercooler pipes going to the throttle bodies by disconnecting the
MAP sensor, using the pliers to remove the wire locating clips, and removing the two
hoses from the air bypass valve. You will also need to loosen the clamps on the couplers
at the throttle body and the hard pipe inside the fender.
2. Remove the engine grounding strap that goes from the body to the engine.
Remove the 12mm bolt, and disengage the plastic locating tab.
3. Disconnect the MAF sensor connector, and harness locating tab.
4. Loosen the hose that goes to the turbo by using the 8mm socket. Once loose, slide
the hose downward away from the air box.
5.
Remove the 2 10mm bolts that hold the air box to the radiator core support.
6.
Lifting at the rear, free the air box.
7. Remove the front lip under cover by removing the 10mm bolts concealed by the
rubber covers, plastic clips, and the 2 12mm bolts.
8.
Remove the center under cover by removing the 10mm bolts and plastic clips.
9. Remove the two front wheels too allow easier removal of the inner fender liners,
remove the 1 phillips screw and all plastic clips. When removing, you may have to bend
the liner slightly to clearance the axel and brake lines.
10. Remove the front side markers by using the plastic pry tool and gently pressing
inward on the metal lock clip. You can either disconnect the bulb connector or remove
the socket from the bulb housing.
11.
Remove the radiator panel by removing the plastic clips.
12.
Remove the 5 bumper plastic clips
13. Using a quality painters tape, tape the bumper and the fender along the seam to
protect against scratches.

corners of the bumper, pull outward firmly to disengage the clips holding the bumper.
Carefully slide the bumper forward and away from the vehicle.
15. Disconnect electrical connectors from the headlights, also remove the locating
tabs for the headlights.
16. Remove the 10mm bolts that are holding the bumper locating bracket. This is
directly beneath the headlight. (It has been remove in this picture)
17.
Remove the 10mm bolts that secure the headlights to the car. Carefully lift away.
18. Remove the wiring harness clips from the front support beam. Disconnect the
horns, and the AC high pressure switch. Also remove the hood latch cable retaining clips.
19.
Remove the bumper support bracket removing 6 10mm bolts
20.

21. Disconnect the hood latch cable from the latches. Push inward towards the engine
on the plastic lock that holds the cable to the latch.
22. Using a 10mm wrench remove the lower lip support from the crash beam. Gently
bend the support away from the stud.
23.
Remove crash beam by removing 8 12mm bolts. Once removed pull outward.
24. Remove all 10mm bolts that holds the support. The hood latch should only have
the two nearest the engine removed. (The picture shows 1 already removed). There are
two bolts at the bottom near the intercooler hard pipe bolt that are commonly missed.
There is also one bolt behind the A/C condenser piping that needs to be removed. Also
remove the 2 bolts holding the power steering cooler.
25.
Remove intercooler piping from the intercooler.

Remove the air shroud by removing 4 plastic lock connectors.
28.
Remove the wire harness locating tabs that connect to the oil cooler brackets.
29. Loosen the oil lines by removing 4 10mm nuts from the base of the cooler. Oil

Remove the 3 10mm bolts that attach the lower support to the body.
32. Remove the 2 10mm bolts from the upper bracket and remove the cooler from the
vehicle
33.
Recover the refrigerant in the A/C system with approved recovery machine.
34. Disconnect the 2 AC condenser lines using the special service tool. If the tool is

method should be used as a last resort. Once the lines are removed, tape over them to
protect them.
35. Remove the 2 12mm bolts and one 10mm bolt from each side of the AC
condenser support bracket/hood support bracket.

lock.
53. Unbolt the power steering cooler lines from the radiator support, and disconnect
the power steering cooler line coming from the steering rack (indicated by finger in
picture)
54. Disconnect the power steering feed line from the pump. Use several rags to catch
any fluid that would leak.
55.

power steering rack.
72.
Disconnecting transmission cooler lines.
73. Remove the engine drive shaft going to the transmission and the driveshaft going
to the front differential (Loosen the driveshaft bolts where they meet the transmission

by removing the 14 mm bolt and nut.
75. Remove the sway bar end links to allow the front sway bar to swing clear of the
front cradle bolts.

the body.
77. Slowly lift the vehicle free of the engine, paying close attention that nothing has
gotten caught.
78. Installation of the engine is reverse of removal. So, just start here and work your
way backward through this installation manual.
79. Once the engine is installed, add about 5.5-6qts of Mobil 1 engine oil (or oil of
choice) 0w-40.
80. Fill with coolant using 11-12 qts of genuine OEM Nissan long life coolant.
81. Top off power steering fluid using Nissan power steering fluid.
82. Bleed vehicle brakes using either Nissan GTR brake fluid or Motul RBF 600 or

to reach operating temperature with the heater on. Shut vehicle off. Observe engine oil
level and coolant level and correct as needed. NOTE: When hot, cooling systems operate
at high pressure, and when opened while hot will erupt and spray everywhere. This will
cause severe burns or death, SO DO NOT OPEN THE COOLING SYSTEM WHEN
HOT!
