1997 Honda Passport Lug Nut Torque & Bolt Specs

The 1997 Honda Passport lug nut torque is 80 ft-lbs (108 Nm) 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) · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 1997 Honda Passport. 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 1997 Honda Passport

Wheel / lug nut torque and thread spec (covered above)

Repair guidance for this model year

Heads up for 1997 Honda Passport owners: Vehicles this age frequently have seized fasteners due to thread corrosion. Apply penetrating oil (PB Blaster, Kroil) 24 hours before any wrenching, and have a thread chaser on hand. Lug studs are particularly prone to thread damage at this age; if a nut spins on without engaging, the stud is stretched and must be replaced before the wheel goes back on.

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

Frequently asked questions

What is the lug nut torque on a 1997 Honda Passport?

The OEM-specified lug-nut torque for the 1997 Honda Passport is 80 ft-lbs (108 Nm) on M12x1.5 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 1997 Honda Passport lug nuts?

Most modern Honda vehicles use a 19mm or 21mm socket. Older Honda models from before 2000 may use a 13/16" SAE socket on certain trims. Confirm against the actual lug before purchasing aftermarket wheels.

Are the 1997 Honda Passport fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
