ELRING 820.490 Nuts And Bolts

The ELRING 820.490 Nuts And Bolts is a precision‑engineered cylinder head bolt set designed to meet the exacting standards of modern automotive engineering. Crafted from high‑strength alloy steel, each component undergoes rigorous heat treatment and surface finishing processes to ensure optimal performance under extreme pressure and temperature conditions.

Key Features

• Material Integrity: Manufactured from high‑grade alloy steel, the bolts exhibit superior tensile strength, corrosion resistance, and fatigue life. The nuts are forged to maintain consistent torque characteristics.
• Exact Fitment: Designed for a wide range of engines, including Ford Escort, Fiesta RS Turbo CVH, Chery models, Caterham Seven, and Westfield Morgan variants. Each bolt is dimensionally accurate to guarantee seamless integration with cylinder head assemblies.
• Hexagonal Exterior: The nuts feature a standard hexagonal shape for easy handling with common torque wrenches, ensuring precise tightening without cross‑threading or damage.
• Heat Treatment & Surface Finish: Post‑assembly heat treatment locks in the desired mechanical properties. A protective coating resists oxidation and extends service life even under high‑temperature operating conditions.
• OEM Compatibility: The set is engineered to match original equipment specifications, providing a reliable replacement that restores engine integrity without compromising performance.

Applications Across Vehicle Platforms

The versatility of the ELRING 820.490 Nuts And Bolts allows it to be used in numerous automotive platforms:

• Ford Escort & Fiesta RS Turbo CVH (1.1L – 1.6L): Ideal for both domestic and export models, ensuring proper head gasket sealing and valve train stability.
• Chery & Cowin Series: Compatible with a range of engine displacements, providing reliable bolt performance in Asian market vehicles.
• Caterham Seven & Westfield Morgan: Designed to meet the high‑performance demands of lightweight sports cars and touring models.
• Ford Africa & Ford USA Variants: Meets regional specifications for durability and torque requirements in diverse climatic conditions.

Installation Guidelines

Proper installation is critical to achieving optimal engine performance. Follow these steps:

1. Preparation: Clean the cylinder head surface and bolt holes thoroughly. Inspect bolts for any manufacturing defects.
2. Torque Sequence: Apply torque in a star pattern, gradually increasing to the specified value (typically 80–100 Nm depending on engine type). Use a calibrated torque wrench.
3. Uniform Tightening: Ensure all bolts reach the target torque simultaneously to maintain even head gasket pressure.
4. Verification: After initial tightening, recheck torque values after a short running period to confirm stability.

Maintenance & Longevity

The ELRING 820.490 Nuts And Bolts are engineered for long‑term reliability. However, periodic inspection is recommended:

• Check for signs of wear or corrosion on the nuts and bolt heads.
• Verify torque values after major engine service events such as head gasket replacement.
• Avoid over‑tightening during reassembly to prevent thread damage.

Performance Benefits

By using the ELRING 820.490 Nuts And Bolts, vehicle owners can expect:

• Consistent head gasket sealing, reducing the risk of coolant leaks.
• Improved engine durability due to high‑strength fasteners that resist loosening under vibration.
• Enhanced combustion efficiency from precise bolt placement and torque control.
