Function of the Head Gasket
The 021713B Head Gasket is designed to:
- Seal the mating surfaces between the cylinder head and engine block
- Help maintain proper cylinder compression
- Contain combustion pressure within the combustion chamber
- Help prevent combustion gases from escaping
- Keep engine oil separated from the combustion chamber
- Support efficient and dependable engine operation
- Restore the engine’s original sealing functionality
A properly installed OEM head gasket is essential for maintaining compression, combustion efficiency, and overall engine integrity.
Common Signs Replacement Is Needed
Replace the cylinder head gasket if you notice:
- Loss of engine compression
- Difficult starting or failure to start
- Reduced engine power or unstable operation
- Oil leaking near the cylinder head joint
- Combustion gases escaping around the cylinder head
- Excessive engine temperature
- Visible gasket cracking, burning, or deterioration
- Gasket damage discovered during cylinder head removal
A failed head gasket can cause compression loss, oil leakage, overheating, poor combustion, and potentially serious internal engine damage.
Installation & Service Notes
- Shut down the generator and allow the engine to cool completely before servicing.
- Disconnect the spark plug wire and battery, if equipped, to prevent accidental starting.
- Remove the necessary engine components to access the cylinder head.
- Follow the appropriate Generac service procedure for cylinder head removal.
- Remove all old gasket material without scratching or gouging the mating surfaces.
- Inspect the cylinder head and engine block for warping, cracks, or other damage.
- Install the 021713B Head Gasket in the correct position and orientation.
- Tighten the cylinder head fasteners using the specified sequence and torque values.
- Recheck valve clearance and related adjustments when required by the service manual.
- Rotate the engine manually before startup to confirm proper mechanical movement.
- Test the engine and inspect the cylinder head area for leakage or abnormal operation.
Important: Do not reuse a compressed cylinder head gasket. Do not apply gasket sealant unless specifically directed by the Generac service manual. Professional installation is recommended because incorrect surface preparation, gasket orientation, or bolt torque may cause immediate gasket failure or engine damage.
Maintenance Recommendations
- Keep engine cooling passages and ventilation areas clean.
- Maintain the correct engine oil level and recommended oil-change intervals.
- Avoid operating the generator under continuous overload conditions.
- Investigate overheating, compression loss, and oil leakage promptly.
- Check cylinder head fastener torque only when directed by the service manual.
- Replace the head gasket whenever the cylinder head is removed.
- Use genuine OEM replacement parts to maintain proper fit, compression sealing, and long-term engine reliability.
