037121133C Coolant Flange - parts supplier

The part number 037121133C refers to a coolant flange commonly used in Volkswagen, Audi, and other vehicles from the Volkswagen Group. It is a critical component of the cooling system, which helps regulate the engine's temperature.

Here are the main details about the coolant flange:

1. Function: The coolant flange connects the coolant hoses to the engine block or cylinder head. It serves as a junction point through which coolant flows, facilitating the circulation of coolant to maintain optimal engine temperature.

2. Material: It is typically made from high-quality plastic or metal, depending on the specific design and vehicle requirements. The material is chosen for its durability and resistance to heat and corrosion.

3. Location: The coolant flange is usually located near the engine's water pump or thermostat housing. It plays a key role in the flow of coolant between the radiator, the engine, and the heater core.

4. Symptoms of Failure: If the coolant flange fails, it can lead to coolant leaks, engine overheating, or improper coolant flow. This can cause significant engine damage if not addressed promptly.

5. Replacement: Over time, coolant flanges can degrade due to heat and pressure, especially if made from plastic. It is important to check the flange periodically for cracks or leaks and replace it if necessary to avoid costly engine damage.

6. Compatibility: This part is designed to be compatible with specific vehicles within the Volkswagen Group. Ensuring proper fitment is crucial for maintaining the cooling system's integrity.

The coolant flange, although a relatively small part, is vital for the proper functioning of the vehicle’s cooling system, and its failure can lead to serious engine problems.
