Hyundai Sonata Engine Replacement: Smooth, Reliable Power—Restored

Hyundai Sonata Engine

Daily commute. Weekend errands. Highway trips. The Hyundai Sonata is built to make real life easy. When the engine gets tired—loss of compression, oil consumption, or a bottom-end knock—a manufacturer-built remanufactured long block brings back the quiet idle and confident mid-range you expect.

The Gearhead Advantage: We build and test in-house, so quality control, warranty, and support come from the same team—not a broker.

Why choose a remanufactured engine?

  • Known baseline: Standardized teardown, machining, and testing—no mystery history.

  • Consistency: Critical clearances and surface finishes set to spec for ring seal and longevity.

  • Written coverage: Clear warranty terms from the people who built your unit.

  • VIN-verified fitment: We match the exact long block to your year/trim/emissions package.

Common symptoms that suggest replacement

  • Persistent knocking/tapping or metallic debris in oil

  • Low compression or misfires across cylinders

  • Oil consumption with smoke under load or at start-up

  • Overheating damage (warped head, head-gasket failure)

  • Turbo models: boost-related oiling issues or shaft play (we’ll advise on best practices)

What to expect with Gearhead

  • Build & test in-house: Teardown → precision machining → assembly → verification

  • Fitment confirmation: We check VIN, engine code, emissions label, and sensor/reluctor needs

  • Clear warranty: Written coverage included on every quote

  • Nationwide shipping: To your shop or home; core return made simple

  • U.S.-based tech support: Break-in guidance and installer coordination available

Installation & break-in notes (quick hits)

  • Replace cooling components (thermostat, suspect radiator) if there’s any overheating history

  • Use our break-in oil and procedure for the initial run-in period

  • Early oil/filter change is cheap insurance—capture initial wear particles

  • Turbo models: confirm clean oil feed/return lines and proper priming before first start

The Gearhead Advantage

As the manufacturer, we control the build, the test, and the warranty. Brokers and salvage suppliers can’t match that end-to-end accountability. One builder. One warranty. One support team.
