  Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm that the gasket required is for cylinders 4–6.
  
  What Is This Part?

The cylinder head gasket is the sealing layer clamped between the cylinder head and the engine block. Its openings align with the cylinders and the passages crossing this joint. It must seal combustion gases while keeping engine oil and coolant within their respective circuits. Its sealing action depends on the condition of the mating surfaces and the correct clamping force from the cylinder-head fasteners. 

What Does This Part Do?

• Contains combustion pressure: Seals around the combustion chambers at the head-to-block joint.
• Seals coolant passages: Helps prevent coolant escaping across the joint.
• Seals oil passages: Helps contain engine oil where it passes between the block and cylinder head.
• Separates engine circuits: Maintains sealing boundaries between combustion gases, oil and coolant. 
  
  Why Replace This Part?

Replacement may be needed when testing identifies leakage through the cylinder-head joint or inspection reveals damaged sealing areas. Overheating, distorted mating surfaces and incorrect bolt tightening can compromise the seal. A new gasket alone will not correct a warped cylinder head or an unresolved cooling-system fault, so the underlying cause must be investigated during the repair.

During cylinder-head work, have the head and block sealing surfaces checked before reassembly. Follow the engine-specific requirements for surface preparation, fastener renewal and tightening sequence rather than assuming that fitting a gasket is the only work required. 

When to Replace This Part?

• Confirmed joint leakage: Testing identifies combustion-gas, oil or coolant leakage through the head-gasket joint.
• Visible sealing damage: Inspection after dismantling reveals burning, erosion or damage around sealing areas.
• Overheating-related damage: Examination finds gasket damage or distorted mating surfaces following overheating.
• Incorrect previous installation: Inspection reveals misalignment, damaged sealing areas or inadequate clamping. Coolant loss and overheating require diagnosis; neither proves gasket failure on its own.
