6.5.1 Disassembly

NOTE: Perform the operations described in Par. 5.1.

  Important
  • Before proceeding with operation, read Par. 3.3.2.
  • If the engine is fitted with the Poly-V belt, perform the operations described in Par. 11.3.

  1. Loosen the screws A and B.
  2. Push the alternator C in the direction of the arrow D and remove the belt E.
  3. Release clamp F and disconnect tube G from the coolant pump N.

 

NOTE: If union R, is disassembled, replace it or alternatively apply Loctite 2701 on the thread when assembling on pump G (tightening torque of 20 Nm).

6.5.2 Assembly

 

 Important
  • Always replace the gaskets L, after each disassembly.
  • Always replace the belt E after each assembly.
  • If the engine is fitted with the Poly-V belt, perform the operations described in Par. 11.3.
  • To handling components refer to Par. 2.17.
  • Always replace the gaskets (where are provided) after each disassembly

  1. Fit the coolant pump N with the screws H interposing the new gasket L (tightening torque at 25 Nm).
Fig 6.40
  1. Reinsert the pipe G and hook the clamp F (Fig. 6.38).
  2. Rehook the clamp M on the pump N (Fig. 6.39).
  3. Push the alternator C in the direction of the arrow D.
  4. Insert the belt E on the pulleys P.
Fig 6.41
  1. Pull the alternator C in the direction of the arrow Q.
  2. While tensioning the alternator C, first clamp screw A (tightening torque at 25 Nm) and then screw B (tightening torque at 69 Nm [thread M10] - 40 Nm [thread M8]).
  3. Check the tension of the belt E with the instrument (DENSO BTG-2), positioning it in point P (the tension must be between 350 and 450 Nm).
  4. If the tension values do not correspond, tighten screws A and B, then repeat operations 6, 7 and 8.
