What is the torque on the oil drain plug on a ls460?
The oil drain plug on the Lexus LS460 is typically torqued to about 29 ft-lbs (roughly 39 Nm).
In practice, this value comes from the factory service manuals used for LS460 and LS460L models that share the 4.6-liter V8. The goal is to seal the oil pan without risking stripped threads or a leaking gasket. Always confirm the exact spec for your exact model year and any aftermarket drain plug components you might be using, and replace the crush washer with a new one each time you drain the oil.
Official torque specification
The standard specification cited in Lexus service documentation for the LS460’s oil pan drain plug is 29 ft-lbs (39 Nm). This applies to the common LS460 and LS460L configurations that use the 4.6L V8. Using a torque wrench ensures the plug is tight enough to seal without exceeding the thread strength of the oil pan.
- LS460 / LS460L (4.6L V8) — 29 ft-lbs (39 Nm)
- Note: Some aftermarket drain plugs or alternative pan designs may specify up to about 32 ft-lbs (43 Nm). Always consult the exact service manual for your year and hardware.
Below is a concise listing of the typical torque value used across LS460 variants.
Using the correct torque helps prevent oil leaks and minimizes risk of thread damage. If you replace the drain plug or washer, verify the torque again after installation.
Notes on variant specifics
Most LS460 and LS460L models share the same drain plug torque, but there can be small year-to-year variations or aftermarket components. When in doubt, refer to the official Lexus service manual for your exact VIN and model year to confirm the precise value.
Practical torquing steps
To apply the correct torque in a safe, repeatable way, follow these practical steps.
- Before draining, warm the engine briefly to help the oil flow and drain; then place a drain pan beneath the plug.
- Replace the crush washer with a new one designed for the LS460 drain plug.
- Clean the bolt threads and the oil pan thread surface to remove old oil and debris.
- Thread the drain plug by hand to avoid cross-threading, then tighten with a torque wrench to 29 ft-lbs (39 Nm).
- Lower the car, refill the engine with the correct oil grade and amount, and run the engine to operating temperature.
- Check for leaks around the drain plug and recheck torque if you observe seepage after initial warm-up.
Following these steps helps ensure a proper seal and longevity of the drain plug installation, reducing the risk of leaks or damage to the oil pan.
Summary
For the Lexus LS460, the recommended oil drain plug torque is 29 ft-lbs (39 Nm), with a new crush washer, and verification via the service manual for your exact year and variant. Use a torque wrench, avoid overtightening, and check for leaks after refilling and warming the engine. Always consult your specific owner's or service manual to confirm any year-specific variations.
