Standard Tightening Torques
WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.
Each fastener should be tightened to the torque specified in each section. If no torque description or specification is provided in the relevant section, refer to the following TIGHTENING TORQUE CHART for the applicable torque for each fastener. When a fastener of greater strength than the original one is used, use the torque specified for the original fastener.
NOTE:
- For flanged bolts, flanged nuts and self-locking nuts of the 4T and 7T strength classes, add 10% to the applicable tightening torques given in the following chart.
- The following chart is applicable only where the fastened parts are made of steel or light alloy.
