• Masulani wononga bokosi la chingwe ndi zomangira zomangira valavu zopanda ntchito (13). Chotsani valavu ya mpweya yopanda ntchito kuchokera panjira yolowera ndi bulaketi.
• Chotsani valavu ya mpweya wopanda pake pakuthandizira mphira (4).
  
  
  
  Gasket (1) pakati pa valavu ya mpweya yopanda ntchito (2) ndi manifold olowera iyenera kusinthidwa nthawi zonse. Mukasintha gasket, yikani kaye pazomwe mumadya.
• Kuti muthandizire kuyika valavu ya mpweya wopanda pake, thirani mafuta mkati mwa chisindikizo kuti azitha kusuntha.

Kusintha pampu yamafuta kumayenera kuchitika motere. Werengani zambiri za zolakwika za ECU-ECU kuchokera ku DME system, zimitsani kuyatsa. Tsegulani bokosi la magolovu ndikuchotsani.

• Masulani zomangira ndikukokera bokosi la fuse pansi (popanda kulumikiza chingwe).
• Chotsani cholumikizira ku pampu yamafuta.
  
  

Chonde chonde!

Pambuyo pochotsa pampu yamafuta, kiyi yoyatsira ikatembenuzidwira pamalo oyambira, pampu yamafuta simayatsa ndipo injini siyamba.

Kuyika kwa pampu yamafuta kumayenera kuchitidwa motsatana, ndikuwerenga chidziwitso cha ECM cholakwika kuchokera ku DME system. Yang'anani mauthenga olakwika omwe adalowetsedwa. Kuthetsa ndi kufufuta zambiri kuchokera ku zolakwika kukumbukira.
