  🔧 GM Part #25207792 — what it is

  GM Genuine Parts 25207792 Cylinder Head Gasket

  • Official name: Cylinder Head Gasket
  • System: Engine (internal sealing)
  • Type: OEM GM / ACDelco
  • Replaces: 25194171

  ⚙️ What it does

  This is one of the most critical gaskets in the engine:

  • Seals cylinder head to engine block
  • Keeps:
    • Combustion pressure inside cylinders
    • Coolant and oil in separate passages
  • Maintains proper engine compression

  👉 In simple terms: it’s what keeps your engine from mixing oil, coolant, and combustion gases.

  🚗 Common fitment

  Based on OEM data, this gasket is used on newer small GM turbo engines, including:

  • 1.2L 3-cylinder (L3T) engines
  • Found in vehicles like:
    • Buick Encore GX
    • Chevrolet Trailblazer (new gen)

  (Example fitment shown for 2020–2025 Encore GX 1.2L)

  ⚠️ Common symptoms of failure

  Head gasket issues are serious. Watch for:

  • Overheating
  • White smoke from exhaust
  • Coolant loss with no visible leak
  • Milky oil (coolant mixing)
  • Misfires / low compression

  🔧 Replacement notes

  • Major repair (not a quick job)
  • Requires:
    • Removing cylinder head
    • New head bolts (often torque-to-yield)
  • Surfaces must be perfectly flat

  👉 This is not a “quick gasket swap”—it’s a top-end engine rebuild job

  👍 Bottom line

  • 25207792 = cylinder head gasket (modern GM small turbo engines)
  • Replaces older part 25194171
  • Critical for engine sealing — failure = major repair
