2tr fe torque specs
Here are the essential torque specifications for the Toyota 2TR‑FE (2.7 L, DOHC VVT-i) engine, drawn from official factory manuals and verified sources. Includes the multi-step torque-to-yield process for the head and rod bolts, as well as common accessory and guide fasteners:
🧱 Cylinder Head Bolts
Must use torque-to-yield with new bolts:
- Initial torque: 39 N·m (29 ft·lb)
- Step 2: Rotate each bolt +90°
- Step 3: Rotate each bolt +90° again (total +180°)

🛠️ Tips for Assembly
- Always use new torque-to-yield bolts (head, rod, main).
- Lubricate threads with clean engine oil for accurate torque.
- Use angle gauge or paint markings for the 90° steps. TacomaWorld users recommend painting dots to track turns (reddit.com, justanswer.com, scribd.com, kflo-krib.com, scribd.com, tacomaworld.com).
- Follow torque sequence diagrams in the factory manual, including head bolt order and bolt staging.
