VAICO V10-8205 Coolant Flange

Product Overview

The VAICO V10-8205 Coolant Flange is a precision-engineered component designed to secure the coolant system of modern internal combustion engines. It serves as the critical interface between the cylinder head and the cooling circuit, ensuring reliable heat transfer and preventing leaks.

Key Features

• High‑Integrity Seal: Equipped with an integrated gasket that guarantees a leak‑free connection under high pressure and temperature conditions.
• Robust Construction: Manufactured from premium alloy steel, the flange offers exceptional resistance to corrosion, thermal expansion, and mechanical wear.
• Exact Fitment: Designed to match the original specifications of the cylinder head for a seamless installation experience.
• Broad Compatibility: Suitable for a wide range of Audi, Skoda, Volkswagen, and SEAT models, including A4, A6, C5, B5, B6, Passat, Superb, and related variants.
• Easy Installation: Features a standardized bolt pattern that aligns with the engine block, simplifying assembly for technicians and DIY enthusiasts alike.

Material Composition

The flange is fabricated from high‑grade alloy steel (ASTM A193 Grade B8), which provides:

• Excellent Thermal Conductivity – facilitates efficient heat dissipation from the cylinder head.
• Superior Corrosion Resistance – protects against coolant acids and environmental factors.
• High Tensile Strength – withstands the cyclic stresses of engine operation without deformation.

Design Specifications

Installation Guide

1. Preparation: Ensure the cylinder head and engine block are clean. Remove any old gasket material.
2. Positioning: Place the flange onto the coolant passage, aligning it with the bolt holes.
3. Gasket Placement: Slide a new high‑temperature gasket between the flange and the cylinder head surface.
4. Bolt Tightening: Insert bolts through the flange into the engine block. Tighten in a cross‑pattern sequence to achieve even pressure.
5. Leak Check: After assembly, run the cooling system at operating temperature and inspect for any coolant leaks around the flange area.

Maintenance Tips

• Regularly inspect the gasket surface for wear or deformation before each engine rebuild.
• Avoid over‑tightening bolts, which can damage the flange or cylinder head.
• Use a coolant that meets the manufacturer’s specifications to prevent corrosion of the flange material.
