VG1246060057 Drive Belt Tensioner is the automatic tensioning assembly for Sinotruk HOWO A7 D12 engine accessory drive system. It continuously applies stable preload to the serpentine belt of fan, alternator and water pump, to eliminate belt slack caused by engine vibration and load variation. Proper belt tension avoids slipping, abnormal noise and power loss of auxiliary components. Worn tensioner pulley bearing, fatigue failure of internal torsion spring or damping attenuation will cause belt shaking, slipping or even dropping off, which further triggers engine overheating and insufficient power generation. It is an essential replacement spare part for D12 engine belt drive system overhaul.
