Engine Bolt Reuse Guidelines & Torque Specifications For
1996-2003 Hyundai Engines
The AERA Technical Committee offers the following information regarding engine bolt reuse guidelines & torque specifications for 1996-2003 Hyundai engines. This bulletin applies to the cylinder head, connecting rod and main bearing bolts that use the torque angle method for tightening.
It has been determined fasteners that are tightened by the conventional torque only method can have substantial clamping force variation. These variations come from several factors such as fastener friction and hand tightening versus power driver tightening methods. Fasteners that are tightened by a low initial torque value plus tightened and additional angular value are known as ?torque-angle bolts" (or sometimes torque-to-yield bolts). These types of bolts or fasteners can achieve very high clamp loads with very small variation.
