Should windshield wipers be replaced more often?
Windshield wipers aren’t replaced “when they break down,” but rather “when their performance deteriorates.” Windshield wipers are a crucial component for driving safety, especially for trucks that frequently travel long distances.
Clear visibility is the first line of defense for safe driving. Many drivers only think about replacing them when they are completely unusable, which actually hides a huge safety hazard.
Normal conditions:
It is recommended to check/replace them every 6-12 months.
High-frequency use or harsh environments may require more frequent replacement.
Special Note:
Long-haul trucks are frequently exposed to wind, sand, rain, snow, and intense sunlight, causing their windshield wipers to wear out faster than those in passenger cars.
Why do truck windshield wipers wear out faster?
1. Large Windshield Area
Truck windshields have large areas, placing a heavy workload on the wipers.
2. Complex Operating Environment
At high speeds, the large windward surface accelerates the aging of the rubber wipers.
3. High Working Intensity
During long-distance driving, the wipers operate continuously for extended periods.
These signs indicate it’s time to replace your windshield wipers!
1. Decreased Wiping Performance
Leaves streaks or fog-like residue on the glass after wiping. Ineffective at clearing light rain, creating a scattering halo. Numerous tiny water droplets remain after wiping.
2. Abnormal Noises
Makes a “squeaking” or “jumping” sound while wiping.
3. Harsh Sound from Rubber Strip Friction on Glass
These sounds indicate that the rubber strip has hardened and is not adhering properly.
4. Visibly Aging Rubber Strips
Touching the rubber strip reveals hardening, loss of elasticity, cracks, and burrs at the edges, deformation, and lifting, preventing proper adhesion to the curved surface of the glass.
How to Correctly Replace Windshield Wipers?
Selection Points
1. Choose the right model: Wiper blade sizes vary between vehicle models, and the lengths for the driver and passenger sides may also differ.
2. Quality first: Original or well-known brand parts are recommended for better durability.
3. Compatibility check: Verify vehicle model information or measure the length of the original wipers before purchasing.
Installation Notes
1. Clean the windshield before installation to remove oil film and dirt.
2. Install correctly according to the instruction manual or professional guidance.
3. Post-installation test: Spray windshield washer fluid and test wiping to ensure no skipping or abnormal noise, and that the wipers wipe cleanly.
Jiefang Truck Service Tips
1. Regular inspection: Have a technician check the condition of the wipers during each vehicle maintenance.
2. Routine maintenance: Clean the wiper blades while cleaning the glass to extend their lifespan.
3. Parking precautions: Avoid prolonged parking in direct sunlight or extremely cold environments.
4. Winter special care: Before using wipers in snowy weather, check if the wiper blades are frozen to the glass.
Safety is paramount; clear visibility is key.
