Every batch that changed, added, hid or retired a published value on WhatSizeBolt, newest first. Each entry says what changed, what was held back and why, the document it was checked against, and the record in our repository that holds the full change. A wrong torque value is a safety problem, so a correction is never a quiet edit: the old value, the new one and the proof stay on record.
How a correction happens
A value changes only when a maker’s document says something different from what we publish, and the change lands with a proof: the document, the page or section and the manual’s own wording. Evidence records are append-only, so an earlier claim is never overwritten; it is superseded, and the history stays. Rows that no manufacturer document could have produced are hidden rather than deleted, and can be restored with a sourced correction.
Reporting a wrong value
If a figure on the site does not match your service manual, send the page, the fastener and what your manual says through the contact page. Spec corrections are handled before every other kind of message.
Corrections, newest first
— Lug nut torque, round 1: 34 high-traffic model years checked against the owner’s manual
Correction
What changed: 38 lug nut torque values changed to the figure the owner’s manual prints (for example 2014 Chevrolet Camaro 140 → 110 ft-lbs, 2007–2008 Toyota Corolla 80 → 76 ft-lbs, 2018 Hyundai Tucson 80 → 79–94 ft-lbs). 107 existing rows stamped verified, 4 lug rows added where a vehicle had none, 111 proofs attached.
Held back: 79 model years held back: no maker-hosted manual, conflicting figures, or a manual that does not cover every configuration the page lists.
Checked against: Carmakers’ own hosting only (GM owner center, Subaru, Honda and Hyundai technical information sites, Mazda USA, Toyota). Each figure read off the rendered PDF page by a second checker.
— Valve cover bolts: Buick LaCrosse, Regal, Verano and Chevrolet Impala
Addition
What changed: 30 valve cover bolt rows added at 89 in-lbs (10 Nm) across Buick LaCrosse 2010–2016, Regal 2011–2017, Verano 2012–2017 and Chevrolet Impala 2012–2017, with 30 proofs.
Held back: 2017 LaCrosse left out: the GM procedure says 15 Nm while its spec table says 10 Nm.
Checked against: GM service information for each model year, read on a service-manual mirror the site owner supplied.
— Valve cover bolts: GMC Terrain and Chevrolet Equinox 2010–2017
Correction
What changed: 8 GMC Terrain valve cover bolt rows changed from 7 ft-lbs (forum-sourced) to 89 in-lbs (10 Nm) as GM prints it; 24 Equinox rows added; 32 proofs attached. The 2013–2017 Equinox engine label corrected from 3.0L V6 to 3.6L V6.
Checked against: GM service information for each model year, read on a service-manual mirror the site owner supplied. Prompted by a reader asking where the 2017 Terrain valve cover bolts go.
— Axle nut torque checked against the SKF 2023 torque guide; 22 small-engine rows
Correction
What changed: 559 axle nut torque values corrected and 1,842 proofs attached. 22 small-engine and tool fastener rows corrected or verified against the manufacturer’s manual.
Held back: 44 rows held back where the guide and the stored row could not be matched with confidence.
Checked against: SKF 2023 axle nut torque guide, every page in scope rendered and read by three independent checkers; small-engine figures from the engine makers’ manuals.
What changed: 90,476 fastener rows on 4,922 vehicles hidden from the site. They were template sets no manufacturer source could have produced: a generated set of about 107 rows repeated on 770 Ford and Jeep vehicles, and low-confidence name, torque and socket combinations shared across unrelated carmakers.
Held back: Nothing was deleted. Rows with a proof, a manufacturer source or medium or high confidence were never flagged, and any flagged row can be restored with a sourced correction.
Checked against: Internal audit of rows with no source.
— Honda Civic Type R lug nut torque 80 → 94 ft-lbs
Correction
What changed: 2017–2021 and 2023–2025 Civic Type R lug nut torque changed from 80 ft-lbs (108 Nm) to 94 ft-lbs (127 Nm); 8 proofs attached. Civic pages now show the Type R figure as a labelled variant.
Checked against: Honda owner’s manuals on Honda’s technical information site.
— Proofs hosted on a service-manual mirror retired, then restored
Policy
What changed: On 2026-10-06, 73 lug nut proofs whose only source was a third-party manual mirror were retired (60 verified values and 2 conflicts dropped out). On 2026-10-07 the site owner asked for them back and they were restored. Since then every citation on a mirror host is labelled “service-manual mirror” so a reader can tell the document’s author from its host.
Held back: 11 proofs for the 2019 Ford F-350 at 150 ft-lbs stayed retired: those rows now carry Ford’s owner’s-manual 165 ft-lbs.
— Lug nut torque, rounds 2 and 3: owner’s-manual proofs for the top 151 pages
Correction
What changed: Round 2: 49 lug rows added where a vehicle had fasteners but no lug row, 145 proofs attached, 33 notes rewritten where a service-manual aside contradicted the owner’s manual. Round 3: 2019 Ford F-350 lug nut torque 150 → 165 ft-lbs, 2010 Toyota Sienna 76 ft-lbs given its metric figure, one Tundra row renamed, 5 lug rows added, 157 proofs attached.
Checked against: Owner’s manuals for each model year.
— Lug nut torque rewritten to the owner’s-manual figure on 504 rows
Correction
What changed: 504 lug nut torque rows across 163 model years rewritten to the figure printed in that model year’s owner’s manual, each with a proof naming the document, PDF page and the manual’s wording. Largest groups: 118 rows 80 → 79–94 ft-lbs (Hyundai and Kia print a range), 64 rows 80 → 76 ft-lbs aluminum / 83 ft-lbs steel (Toyota), 79 rows 150 ft-lbs (203 Nm) → 150 ft-lbs (204 Nm) as Ford prints it.
Checked against: Owner’s manuals for each model year.
