Water Reservoir Bleeder Valve
The water reservoir bleeder valve (7P5121671A / A1216152) is a key cooling system component that regulates pressure and allows trapped air to escape from the expansion tank. By ensuring consistent coolant circulation and correct pressure balance, it prevents overheating and maintains long-term engine reliability.

What the Product Does

• Maintains correct cooling system pressure.
• Releases trapped air bubbles for efficient coolant flow.
• Helps protect against overheating and coolant loss.
• Works with the reservoir and radiator to stabilise engine temperature.

Symptoms of a Failing Bleeder Valve

• Coolant leaks around the expansion tank area.
• Engine overheating or fluctuating temperature gauge.
• Gurgling or bubbling noises from the reservoir.
• Low coolant warnings despite no visible leaks.
• Pressure escaping or hissing sounds near the tank cap/valve area.

Common Reasons for Failure

• Seal Wear: Rubber seals inside the valve degrade with age and heat.
  
• Cracking: Plastic housings can crack from repeated heat cycles.
  
• Contamination: Dirt or poor coolant quality can cause valve sticking.
  
• High Mileage: Natural wear from years of pressure fluctuations.

Why Replace?

• Prevents airlocks and overheating that can damage the engine.
• Restores proper cooling system pressure balance.
• Eliminates coolant leaks and protects against costly repairs.
• Ensures long-term system reliability when paired with fresh coolant.
