ELRING 401.820 Seals

Elring 401.820 Cylinder Head Gasket

The Elring 401.820 is a high‑performance cylinder head gasket designed for a wide range of Volkswagen and Ford engines, including the 2.8 L V6 found in models such as the Jetta, Golf, EuroVan, and Galaxy. This gasket delivers reliable sealing under extreme operating conditions, ensuring optimal engine performance and longevity.

Key Features

• Multi‑layer Construction: The gasket incorporates a multi‑layer steel (MLS) core sandwiched between high‑temperature silicone layers. This design provides excellent resistance to heat, pressure, and chemical exposure.
• Precision Machining: Each component is machined to tight tolerances, guaranteeing a perfect fit on the cylinder head and block surfaces. The result is minimal leakage and consistent compression across all cylinders.
• High‑Temperature Resistance: Engine operating temperatures can exceed 200 °C. The silicone layers in the 401.820 maintain flexibility and sealing integrity up to 260 °C, preventing gasket failure during prolonged high‑load operation.
• Corrosion Protection: Stainless steel reinforcement prevents corrosion from coolant and oil contaminants, extending the gasket’s service life even in harsh environments.
• Compatibility with Multiple Engine Configurations: The gasket is engineered to fit 83.5 mm bore engines, making it suitable for a variety of V6 and inline‑4 configurations across both Volkswagen and Ford platforms.

Installation Guidelines

1. Preparation: Clean the cylinder head and block surfaces with a solvent to remove old gasket material, oil, and coolant residues.
2. Alignment: Place the 401.820 on the engine block, ensuring that all mounting holes align precisely with the head bolts.
3. Torque Sequence: Tighten the head bolts in a star pattern to the manufacturer’s specified torque (typically 140–160 Nm for VW engines). Re‑torque after the first full rotation to ensure even pressure distribution.
4. Cooling System Check: After reassembly, fill the cooling system with fresh coolant and purge air pockets. Verify that there are no leaks before starting the engine.

Performance Benefits

• Consistent Compression: The precise fit of the 401.820 maintains uniform compression across all cylinders, enhancing power output and fuel efficiency.
• Reduced Engine Wear: By preventing coolant or oil leaks into combustion chambers, the gasket protects pistons, valves, and head surfaces from corrosion and erosion.
• Longer Service Intervals: The durable construction allows for extended intervals between maintenance cycles, saving time and reducing downtime.
• Improved Reliability: High‑temperature silicone layers resist degradation under prolonged heat exposure, ensuring reliable operation even in high‑performance or turbocharged engines.

Applications Across Vehicle Models

The Elring 401.820 is widely used across several vehicle families:

• Volkswagen Jetta (1999–2004)
• Volkswagen Golf Mk IV and later models
• Volkswagen EuroVan and Transporter series
• Ford Galaxy Mk I (WGR) 2.8 L V6 (1995–2002)
• Ford BORA, Sharan, and other MPV platforms sharing the same engine architecture

Quality Assurance & Compliance

The gasket is manufactured under strict quality control protocols, meeting ISO 9001 standards. Each batch undergoes pressure testing, dimensional verification, and thermal cycling to ensure compliance with OEM specifications.

Maintenance Tips

• Inspect the gasket surface for scratches or dents before installation; any damage can compromise sealing performance.
• Avoid using excessive torque on head bolts; over‑tightening can deform the gasket and lead to leaks.
• When reassembling, use a fresh set of head bolts if they show signs of wear or corrosion.

Conclusion

The Elring 401.820 Cylinder Head Gasket exemplifies engineering excellence in sealing technology. Its multi‑layer construction, high‑temperature resilience, and precise fit make it the preferred choice for both everyday driving and demanding performance scenarios across a broad spectrum of Volkswagen and Ford engines.
