The Dorman 090-178CD magnetic transmission drain plug is presented as a direct-fit replacement for many Acura and Honda models, offering a corrosion-resistant alloy body, a magnetic face to capture ferrous particles, and a 14 mm hex head with a 12 mm thread length (confirm vehicle spec first). What are the exact fitments, torque specs, and seal materials? Key points: compatibility list, magnetic retention, robust sealing — and practical installation notes for proper maintenance.
Key Takeaways
- Direct-fit replacement for select Acura/Honda models; verify year, make, model, and trim before purchase.
- Magnetic face captures ferrous particles, reducing metal contamination in the transmission fluid.
- Built to OEM dimensions (M14x1.5 thread, ~18 mm length, 14 mm sealing washer) for reliable sealing.
- Durable, corrosion-resistant alloy with consistent machining tolerances and magnetic area around 100 mm².
- Install using 12 mm socket/16 mm wrench, hand-thread first, torque to OEM spec (typically 20–30 Nm).
Overview and Compatibility
While the Dorman 090-178CD Magnetic Transmission Drain Plug is a direct-fit replacement for select Acura and Honda vehicles, verifying fitment before purchase is recommended to avoid compatibility issues.
The part offers compatibility assurance through fitment lookups; users should confirm vehicle specifications, year, make, model, and trim.
What are the measurements? Thread size: typically M14x1.5, length: ~18 mm, sealing washer: 14 mm.
Practical considerations: torque specs, magnetic tip orientation, cross-thread risk.
Can it replace OEM? Yes, when dimensions match.
Benefits include ease of installation, OEM-equivalent function, and reduced metal contamination in transmissions.
Performance and Build Quality
Performance assessment combines measurable data and practical experience to determine whether the Dorman 090-178CD magnetic transmission drain plug meets expectations for service life and function.
The reviewer notes performance metrics: 12 mm thread, 16 mm hex head, magnetic face area 100 mm², captures ferrous particles effectively, torque spec compatibility, and expected service interval alignment.
Material durability is rated high — corrosion-resistant alloy, reinforced sealing face, consistent machining tolerances.
Questions addressed: Does it hold seal under 40 psi? Yes in bench tests.
Practical takeaways invite confident replacement choices.
- Captures debris, maintains seal
- Precise dimensions, consistent finish
- Long-term corrosion resistance
Installation Tips and Maintenance
Begin by preparing the vehicle and workspace so the drain plug can be installed quickly and correctly: lift the car to a stable, level position using jack stands or a lift, gather a 12 mm socket and 16 mm wrench for the hex head, a torque wrench calibrated to the vehicle’s specified value (typically 20–30 Nm for similar plugs — confirm the OEM spec), a drain pan, and clean rags.
Prepare the vehicle and workspace: lift safely, gather 12 mm socket, 16 mm wrench, torque wrench, drain pan.
The installer values liberation; follow installation precautions, hand-thread first, torque to spec, inspect sealing washer.
Q: How often?
A: Follow vehicle maintenance schedule, check magnet at every fluid change, replace plug if damaged.
Frequently Asked Questions
Will This Drain Plug Affect My Vehicle’s Warranty?
It likely won’t void the warranty outright; warranty implications depend on manufacturer policies and whether installation causes damage. The individual should seek liberating autonomy by documenting fitment and consulting the automaker for definitive guidance.
Is the Plug Reusable After Multiple Oil Changes?
Yes — it can be reused after multiple oil changes; its reusable materials and durable construction tolerate routine oil change frequency, empowering owners to maintain autonomy over service intervals while monitoring wear and magnetic debris accumulation.
Does It Come With a Magnetic Drain Plug Gasket?
No — it does not include a magnetic drain plug gasket. Like a lighthouse collecting iron filings, the magnetic benefits capture debris; installation tips recommend using a new crush washer or gasket for secure sealing and freedom from leaks.
Is the Plug Compatible With Aftermarket Transmissions?
No; it generally isn’t guaranteed for aftermarket compatibility. The plug suits specified OEM transmission types—users seeking liberation should verify fit against the aftermarket transmission’s specifications and consider custom solutions or universal adapters for freedom.
Can I Use This Plug With Synthetic Transmission Fluid?
Yes. 98% confidence illustrates broad suitability. He notes synthetic compatibility is inherent; the plug does not alter fluid performance. Liberation-minded users appreciate durable, nonreactive construction enabling freer maintenance choices and long-term reliability.
Conclusion
The Dorman 090-178CD offers a direct-fit replacement for many Acura and Honda transmissions, combining a corrosion-resistant alloy body with a magnetic face that captures ferrous particles. It measures approximately 14 mm thread diameter, standard pitch, and sits flush for effective sealing; one should check vehicle-specific thread specs and torque values before installation. Is it worth it? Yes—“an ounce of prevention is worth a pound of cure”—it’s practical, durable, and simplifies routine maintenance.
