ELRING 006.702 Seals

Overview

The ELRING 006.702 Cylinder Head Gasket is a high‑performance sealing solution engineered for the Alfa Romeo family of engines, including the 147, 156, 166, GTV and Spider models. Crafted with precision multilayer steel (MLS) construction, this gasket delivers superior pressure containment, thermal stability, and long‑term reliability in demanding automotive applications.

Design & Materials

The gasket features a 0.5 mm thick MLS core that combines multiple layers of steel with an advanced sealing compound. This configuration provides:

• Exceptional pressure resistance – maintains integrity under high combustion pressures.
• High temperature tolerance – withstands operating temperatures up to 400 °C without degradation.
• Corrosion protection – the steel layers are treated to resist oxidation and wear.
• Consistent sealing surface – engineered to match the exact contour of Alfa Romeo cylinder heads, ensuring a uniform seal.

Performance Characteristics

When installed correctly, the ELRING 006.702 gasket delivers:

• Leak‑free operation – eliminates coolant and oil leaks at the head joint.
• Improved combustion efficiency – maintains optimal compression ratios for better fuel economy.
• Reduced engine wear – protects internal components from pressure spikes and thermal shock.
• Extended service life – designed to last through multiple engine cycles without failure.

Compatibility

This gasket is specifically engineered for the following Alfa Romeo models:

• 147 (AR32310/36301)
• 156 (932, 936)
• 166 (937)
• GTV / Spider (916S_ 2.0 T.SPARK 16V)

The dimensions are 84 mm × 16 mm, matching the standard head clearance for these engines. It is also suitable for certain Fiat applications where the same head geometry is used.

Installation Guidelines

1. Preparation: Clean all mating surfaces thoroughly to remove oil, coolant, and debris.
2. Alignment: Place the gasket on the cylinder head ensuring that the central hole aligns with the valve cover bolt pattern.
3. Torque Sequence: Tighten the head bolts in a cross‑pattern sequence to the manufacturer’s specified torque (typically 120 Nm). Use a calibrated torque wrench for accuracy.
4. Check for Gaps: Inspect the gasket for any visible gaps or misalignments before final tightening.
5. Reassembly: Reinstall all components, ensuring that coolant and oil lines are correctly connected.

Maintenance & Inspection

While the ELRING 006.702 gasket is designed for durability, periodic inspection during routine maintenance can preempt potential issues:

• Visual Check: Look for signs of cracking or deformation after engine overhauls.
• Leak Test: Perform a pressure test on the cooling system to confirm seal integrity.
Replacement Interval: Replace the gasket during any major head service, such as valve train overhaul or head resurfacing.

Quality Assurance

The gasket undergoes rigorous testing at ELRING’s manufacturing facilities:

• Pressure Testing – verifies seal performance under simulated engine loads.
• Thermal Cycling – ensures material stability across temperature extremes.
Dimensional Accuracy – measured to ±0.01 mm tolerance for perfect fit.

Conclusion

The ELRING 006.702 Cylinder Head Gasket is a premium, OEM‑grade component that delivers reliable sealing performance for Alfa Romeo engines. Its multilayer steel construction, precise dimensions, and proven durability make it an essential part of any engine rebuild or head service aimed at restoring optimal power, efficiency, and longevity.
