2009 Acura Tsx Lug Nut Torque & Bolt Specs

The 2009 Acura Tsx lug nut torque is 80 ft-lbs (108 Nm), tightened with a 19mm socket on M12x1.5 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass.

Lug nut torque: 80 ft-lbs (108 Nm) · Socket size: 19mm · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 2009 Acura Tsx. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

Honda's lug-nut torque sits at 80 ft-lbs (108 Nm) for nearly every passenger model from 1998 onward, with an M12x1.5 thread on most cars and the larger 14mm thread on Ridgeline and Pilot. The 19mm socket Honda uses is one of the only OEM oddities in the Japanese lineup — bring a 19mm with you, not just a 21mm. Honda factory torque values for engine oil drain plugs are unusually low (29 ft-lbs on most engines) and the crush washer is single-use, so replace it every oil change.

Common fastener categories on the 2009 Acura Tsx

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)

Repair guidance for this model year

For 2009 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly
