3sz-ve 1.5 torque settings for big end/main bearings/cylinder head.
Apr 8, 2013 at 2:50 PM
For the 3SZ-VE, tighten big-end bolts to 29 Nm and then turn them 90 degrees. Tighten main-bearing bolts to 30 Nm and then to 60 Nm. Tighten cylinder-head bolts to 29 Nm, followed by two successive 90-degree turns. Use a torque wrench and the specified tightening sequence.
The owner of a 2006 Toyota with a 3SZ-VE 1.5 engine asked for big-end, main-bearing, and cylinder-head torque settings. An expert provided staged torque values for all three and linked a video on using a torque wrench. Later posts asked about unrelated engines and vehicles, and another expert directed one of those requests to a new thread.
