In order to get the best performance out of the ATTESA system, it should be bled. Often after a clutch swap, it is not bleed correctly.

  • Locate oil reservoir in trunk and check level. The top line is the full mark. This one is above the high mark.

  • Locate air bleed connector. In an R34 its in a panel under the dash. In and R32/R33 its in the drivers side kickpanel. Connect and disconnect this wire to run the ATTESA pump.

  • Under the car on the transfer case, below the driveshaft, above the line going to the transfer case is a 10mm bleeder screw.

  • Open and close the air bleeder to bleed air out of the system,while connecting and disconnecting the air bleed connector.
