Windshield Washer Tubes: Signs of Failure and Maintenance Guide

Common Signs of Failure

1. No Washer Fluid Spray
When you activate your windshield washers and nothing comes out, despite having fluid in the reservoir, this could indicate a blocked or damaged tube.

2. Weak or Misdirected Spray
If the washer spray pattern is weak or spraying in the wrong direction, this might indicate a partially blocked tube or a tube that has become loose from its connections.

3. Visible Fluid Leaks
Puddles of washer fluid under your vehicle or visible drips near the windshield could indicate a cracked or split tube.

4. Cracked or Brittle Tubes
Visual inspection may reveal tubes that have become brittle, cracked, or damaged due to age and exposure to engine heat and environmental factors.

Maintenance Schedule

Regular Inspection:
• Inspect tubes visually every 6 months
• Check for proper spray pattern during routine car washes
• Examine connections and mounting points annually

Preventive Maintenance:
• Replace tubes every 5-7 years as preventive maintenance
• Clean nozzles and check for blockages every 12 months
• Flush system with clean water annually to prevent mineral buildup

Additional Considerations:
• Replace tubes immediately if any cracks or leaks are found
• Consider replacing tubes when performing other major engine work
• Use winter-grade washer fluid in cold climates to prevent tube damage from freezing

Note: These maintenance intervals are general guidelines. Actual service needs may vary based on climate, driving conditions, and vehicle usage patterns.
