• Corrosion Protection: Surface treatment includes a phosphate coating, enhancing resistance against rust and extending service life.

Applications in Automotive Cooling Systems

The V20-7149 is engineered for use in a variety of cooling system configurations, including:

• Engine Coolant Lines: Securing connections between the radiator, water pump, and engine block.
• Thermostat Housing: Providing a stable mounting point for thermostat assemblies.
• Radiator Hoses: Attaching hoses to radiators or intercoolers with high reliability.
• Cooling System Modifications: Ideal for aftermarket cooling upgrades where precise flange fittings are required.

Installation Guidelines

1. Preparation: Clean the mating surfaces thoroughly to remove oil, dirt, and old gasket material. Inspect for any damage or deformation before installation.
2. Gasket Placement: Apply a compatible high‑temperature gasket between the flange face and the mating component. Ensure even coverage without gaps.
3. Tightening Sequence: Use a torque wrench to tighten the flange bolts in a cross‑pattern sequence. Follow the manufacturer’s recommended torque value (typically around 12–15 Nm) to avoid over‑ or under‑tightening.
4. Leak Testing: After installation, perform a pressure test or run the engine at operating temperature to confirm the integrity of the seal.

Maintenance Tips

• Regularly inspect flange bolts for signs of loosening or corrosion. Re‑torque as necessary during routine maintenance intervals.
• Avoid using abrasive cleaners on the gasket surface; opt for mild detergents that do not compromise seal integrity.
• When replacing gaskets, ensure the new gasket material matches the original specifications to maintain optimal sealing performance.
