Torque specs › Disclaimer
Last updated November 8, 2026.
Torque Once is a free reference built by an enthusiast for enthusiasts. It is a starting point, not a substitute for the factory service manual or the instructions that come with your parts.
The torque figures, sequences, and procedures on this site are compiled from published sources, which are listed on each page. They are provided for general reference. Where sources disagree, the disagreement is shown rather than hidden, but no figure on this site is guaranteed to be accurate, complete, or correct for your engine.
Specifications vary by model year, engine version, block and head material, fastener type, and lubricant. Aftermarket parts often have their own figures that differ from factory numbers. Always check the specification against a factory service manual for your exact engine and against the instructions supplied with any aftermarket part. Where they differ from this site, follow them, not us.
Engine work carries a real risk of injury and of damage to parts and vehicles. Under-tightened or over-tightened fasteners can cause leaks, failures, and engine damage. By using this site you accept that you are responsible for the work you do and for checking every figure you use.
This site and its content are provided "as is", without warranties of any kind, express or implied. To the fullest extent permitted by law, the owner of this site is not liable for any loss, damage, or injury arising from use of, or reliance on, any information here.
Torque Once is an independent site. It is not affiliated with, sponsored by, or endorsed by any vehicle, engine, or parts manufacturer, or by any retailer.
All manufacturer, brand, vehicle, engine, and part names that appear on this site are trademarks or registered trademarks of their respective owners. They are used only to identify the engines and parts that the specifications apply to. Their use does not imply any affiliation with or endorsement by the trademark owner.
Retailers, manufacturers, and publications cited as sources are named so you can check the figures yourself. Citing a source does not mean it endorses this site, and this site has no business relationship with them.
Specs get corrected as better sources turn up. If you find a figure that disagrees with your service manual, trust the manual.
