1. First of all, you need to find out what is causing the washer fluid reservoir to leak.For example, over time, the plastic material of the reservoir can become brittle due to exposure to temperature changes and environmental factors, leading to cracks. Then, the loose or damaged hose connections may also cause the leaking. If the hoses that connect the washer fluid reservoir to the washer nozzles were loose or damaged, the connection points will leak too. Beyond, the reservoir may have seals or gaskets that prevent leaks, but these can wear out or become damaged, leading to fluid leakage. In addition, physical damage is always a huge possibility. Accidents, collisions, or impacts to the front of the vehicle can damage the reservoir or its mounting, causing leaks.

Afterwards, Here Are the Steps to Fix Washer Fluid Reservoir Leaks:

  1. Locate the Leak:
    • Inspect the washer fluid reservoir and the area around it to identify the source of the leak. Look for visible cracks, loose hose connections, or damaged seals.
  2. Tighten Hose Connections:
    • If the leak is originating from a loose hose connection, use a screwdriver or appropriate tool to tighten the connection securely.
  3. Replace Damaged Hoses:
    • If the hoses are damaged, cracked, or worn, replace them with new ones. Ensure the replacement hoses are the correct size and type for your car.


  1. Repair Cracks:
    • If you find cracks in the reservoir, you can attempt to repair them using epoxy or a plastic repair kit specifically designed for automotive applications. Follow the manufacturer's instructions for the repair product.
  2. Replace Seals or Gaskets:
    • If the seals or gaskets are the source of the leak, replace them with new ones. It's essential to use proper replacements to ensure a secure seal.
  3. Check for Physical Damage:
    • If the reservoir or its mounting is physically damaged, you may need to replace the reservoir with a new one. Check for any other damage in the surrounding area and repair as necessary.
  4. Test for Leaks:
    • After making the repairs, refill the reservoir with washer fluid and test the system to ensure there are no more leaks. Operate the wiper system and verify that the fluid is not leaking from any of the repaired areas.


If you're uncomfortable with diagnosing or fixing the leak yourself, it's best to seek assistance from a qualified mechanic or automotive service center.
