2UZ FE torque specs
Here are the key torque specifications for the Toyota 2UZ‑FE V8 (4.7 L) engine, based on factory and verified third-party sources. This includes fastener values for the main structural and mechanical components—targeting rebuilds, top-end work, or general engine service:
🧱 Cylinder Head Bolts
- Step 1: 24 ft‑lb (33 N·m)
- Step 2 & 3: Turn each bolt +90°, then another +90° (total +180°) (forum.ih8mud.com)
This torque-to-yield sequence is critical—especially for 2000–2009 models—and avoids overtightening. Always use new head bolts. (torkspec.com)
🏗️ Main (Crankshaft) Bearing Cap Bolts
- Step 1: 20 ft‑lb (27 N·m)
- Step 2: Turn each bolt +90° (torkspec.com)
🔩 Connecting Rod Cap Bolts
- Step 1: 18 ft‑lb (24 N·m)
- Step 2: Turn each bolt +90° (charm.li)
⚙️ Camshaft Timing Tube Center Bolt
- Torque to 58 ft‑lb (79 N·m) (torkspec.com)
🔧 Intake & Exhaust Manifolds
- Intake manifold bolts: 13 ft‑lb (18 N·m) (rodsshop.org)
- Exhaust manifold nuts: 32 ft‑lb (44 N·m) (rodsshop.org)
🛢️ Oil System
- Oil drain plug: 29 ft‑lb (39 N·m) (rodsshop.org)
- Oil filter housing/drain plug: 9 ft‑lb (12 N·m)
- Oil pan bolts:
- Lower bolts: 6 ft‑lb (7 N·m)
- Upper bolts: 6–21 ft‑lb (7–29 N·m), depending on bolt size (rodsshop.org)
- Oil pick-up tube: 6 ft‑lb (8 N·m) (rodsshop.org)
- Oil pump mounting:
- 12 ft‑lb (16 N·m) for 12 mm bolts
- 23 ft‑lb (31 N·m) for 14 mm bolts
- Oil pump body cover: 7 ft‑lb (10 N·m) (rodsshop.org)
🔁 Drive / Flexplate & Pulleys
- Flexplate to crankshaft:
- Step 1: 22 ft‑lb (30 N·m)
- Step 2: +90° (rodsshop.org, forum.ih8mud.com)
- Flexplate to torque converter: 35 ft‑lb (48 N·m) (rodsshop.org)
- Crankshaft pulley bolt: 181 ft‑lb (246 N·m) (rodsshop.org)
⏱️ Timing & Accessory Bolts
- Camshaft sprocket/timing tube pulleys/clutch: 6 ft‑lb (8 N·m)
- Timing chain guides/damper bolts: 15 ft‑lb (20 N·m) (rodsshop.org)
- Timing belt/idler/tensioner bolts: 26 ft‑lb (35 N·m) for idler; 12–19 ft‑lb (16–26 N·m) for tensioners
- Drive belt tensioner: 12 ft‑lb (16 N·m)
🔍 Valve Cover & Miscellaneous
- Valve cover bolts: 7 ft‑lb (10 N·m) (rodsshop.org)

🛠️ Best Practices
- Always use a calibrated torque wrench, especially for low-torque specs.
- Replace torque-to-yield bolts (head, main, rod) with new OEM parts.
- Follow angular-tightening precisely—mark bolts and track rotations.
- Lubricate threads with clean engine oil for accuracy.
- Tighten in proper sequence, particularly on head and bearing caps—always refer to service manual diagrams.
