037121133E Coolant Flange - wholesale parts

The part number 037121133E refers to a coolant flange, which is a component used in the cooling system of various vehicles, particularly in Volkswagen, Audi, and other brands under the Volkswagen Group.

Here are the main details about the 037121133E Coolant Flange:

1. Function: The coolant flange serves as a connection point for coolant hoses within the engine's cooling system. It allows coolant to flow through the engine, connecting different parts of the cooling circuit (such as the water pump, thermostat, and cylinder head) to maintain proper engine temperature.

2. Material: Typically made from high-quality plastic or aluminum, the material choice ensures resistance to the high heat and pressure conditions present in the engine's cooling system. Plastic versions are more common for lightweight applications, while aluminum can be used for higher durability.

3. Location: The coolant flange is usually located near the engine's cylinder head or thermostat housing. It connects coolant hoses to ensure the proper circulation of coolant to and from the engine and radiator.

4. Symptoms of Failure: Over time, the coolant flange can degrade due to exposure to heat and pressure. Common signs of failure include coolant leaks, visible cracks, engine overheating, or loss of coolant pressure. If the flange cracks or leaks, it can lead to engine overheating and potentially severe engine damage.

5. Importance: The coolant flange is a small but vital part of the cooling system. A failure can compromise the engine’s temperature regulation, leading to overheating, reduced engine performance, and potential damage to the engine or other components.

6. Replacement: If a coolant flange begins to fail, it’s crucial to replace it promptly. The part is generally inexpensive and easy to replace compared to the cost of repairing engine damage caused by overheating.

7. Fitment: The part number 037121133E is designed to fit specific Volkswagen and Audi models, typically for vehicles with 1.8T engines or other similar configurations. Always ensure compatibility with the vehicle’s make, model, and engine type before purchasing.

Regular inspection of the cooling system, including components like the coolant flange, helps ensure optimal engine performance and longevity.
