    2. Install a new gasket and the urea injector set to the front exhaust pipe assembly with 2 new nuts.

      Torque:
      30 N*m  { 306 kgf*cm, 22 ft.*lbf }

    3. Connect the connector to the urea injector set.

  2. CONNECT UREA TUBE WITH HEATER ASSEMBLY

    Note

    Check for dirt or mud on the urea injector set and around the urea tube connector before connection. Clean if necessary.


    1. Connect the urea tube with heater assembly to the urea injector set.

      Tech Tips

      If there is any solidified urea solution (white solids) on the connection areas of the urea tube with heater assembly and urea injector set, clean the solids off with water. Otherwise, they may prevent the O-ring from sealing properly.


      1. Wash the connection area of the urea tube connector with water to remove all solidified urea solution (white solids).

      2. Wipe off the connection area of the urea injector set with water to remove all solidified urea solution (white solids).
