VAICO V10-9709 Coolant Flange

VAICO V10-9709 Coolant Flange

The VAICO V10-9709 Coolant Flange is a precision-engineered component designed to fit seamlessly into the cooling systems of a wide range of Volkswagen Group vehicles. Whether you are working on an Audi A6, a VW Transporter, or any other model that utilizes the 074121121B coolant line, this flange delivers reliable performance and durability.

Key Features

• Exact OEM Fitment: Manufactured to match the original specifications of the Volkswagen Group, ensuring perfect alignment with the engine block and cooling passages.
• High-Quality Material: Made from hardened steel or aluminum alloy (depending on the variant), providing excellent resistance to corrosion, heat, and pressure fluctuations.
• Robust Thread Design: The flange features a threaded interface that mates securely with the coolant pipe, preventing leaks even under high operating temperatures.
• Longitudinal Pipe Compatibility: Designed for longitudinal coolant pipes, making it ideal for front-mounted radiator connections in many VW and Audi models.
• Easy Installation: The flange’s shape and dimensions allow for straightforward assembly with standard tools, reducing labor time during maintenance or repair.

Vehicle Compatibility

The V10-9709 Coolant Flange is engineered to fit the following vehicle families:

• Audi 100 (C4), A6, and other C-series models – particularly those produced between 1990‑1994.
• Volkswagen Transporter (LT, Eurovan, Caravelle) IV, LT 28‑46 II – both 2.4L and 2.5L engine variants.
• Audi A6 100 C4 Saloon 4A2 – models from the early 1990s.
• Other VW/Audi vehicles with the 074121121B coolant line, including various LT and IV series trucks and buses.

Because of its universal design within the Volkswagen Group, the flange is also commonly used in aftermarket swaps and restoration projects where authenticity and performance are paramount.

Installation Guide

1. Preparation: Clean the coolant pipe and engine block surfaces to remove any debris or old gasket material. Ensure that the threads on both the pipe and flange are free from corrosion.
2. Threading: Apply a thin layer of thread sealant (compatible with automotive cooling systems) to the flange’s threaded end. This step helps prevent future leaks.
3. Assembly: Align the flange with the coolant pipe, then screw it in place using a torque wrench set to the manufacturer’s recommended value (typically around 15–20 Nm for most models).
4. Testing: Once installed, fill the cooling system with fresh coolant and run the engine. Check for any signs of leakage at the flange connection.

Maintenance Tips

• Inspect the flange periodically for signs of wear or corrosion, especially if the vehicle operates in harsh climates.
• Avoid over-tightening during reassembly; excessive torque can damage threads and compromise the seal.
• If you notice any coolant loss, replace the flange immediately to prevent engine overheating.
