2017 Nissan Sentra Windshield Wipers Size

The 2017 Nissan Sentra, a compact sedan popular for its fuel efficiency and reliability, relies on properly functioning windshield wipers for safe driving. Understanding the specific wiper blade sizes, engineering considerations, and performance characteristics is crucial for automotive professionals tasked with maintenance, repair, and parts replacement. This article delves into the specifics of the 2017 Sentra's windshield wipers, offering a comprehensive analysis of size, alternatives, performance, and future trends.

2017 Nissan Sentra Windshield Wiper Size: Technical Specifications

The 2017 Nissan Sentra uses two different wiper blade sizes for the front windshield. The driver's side blade is typically 28 inches in length, while the passenger's side blade is 15 inches. It's important to note that these are the most common sizes, and while generally consistent across trim levels, verifying the existing blade length before replacement is always recommended to avoid fitment issues. Deviation from these sizes, even slightly, can negatively impact wiping performance, potentially leaving unwiped areas on the windshield and compromising visibility.

While the rear wiper is not present on all Sentra models (particularly on the base trim), it's crucial to consider this for models equipped with one. The rear wiper blade size for the 2017 Sentra, where applicable, is 12 inches.

Engineering Choices and Performance

The specific blade sizes used in the 2017 Sentra are not arbitrary. Nissan engineers carefully selected these dimensions based on several factors:

Windshield Curvature: The windshield's curvature dictates the optimal blade length to ensure even pressure distribution across the glass surface. A blade that is too long or too short will not conform properly to the curvature, leading to streaks and missed spots.
Wiping Pattern: The wiper motor and linkage system are designed to move the blades in a specific pattern. The chosen blade sizes complement this pattern, maximizing the wiped area and minimizing overlap.
Aerodynamics: At highway speeds, wind resistance can significantly affect wiper performance. The blade size and shape contribute to the overall aerodynamic profile, minimizing lift and ensuring consistent contact with the windshield.
Visibility Requirements: The primary function of the wipers is to provide a clear field of vision for the driver. The blade sizes are selected to wipe the area of the windshield most critical for driver visibility.

The difference in length between the driver and passenger side blades allows for optimal cleaning of the driver's field of view, which is wider and requires more coverage.

Real-World Performance

The stock wiper blades on the 2017 Sentra generally offer adequate performance in light to moderate rain. However, in heavy downpours or during winter conditions with snow and ice, the performance can be less than ideal. Factors that impact the wiper blade's real-world performance include:

Rubber Compound: The quality of the rubber used in the blade's squeegee is critical. Softer, more pliable rubber tends to conform better to the windshield and provide a cleaner wipe.
Blade Design: Conventional, beam, and hybrid blade designs each offer different performance characteristics. Beam blades, for example, tend to distribute pressure more evenly, resulting in less streaking.
Windshield Condition: A clean and well-maintained windshield is essential for optimal wiper performance. Dirt, grime, and road debris can all reduce the effectiveness of the blades.
Wiper Arm Pressure: The pressure exerted by the wiper arm on the blade is crucial. Weak or worn wiper arms can result in insufficient pressure, leading to streaking and poor wiping performance.

Alternatives and Comparisons

Several aftermarket wiper blade options are available for the 2017 Nissan Sentra. These alternatives often boast improved performance, durability, or specialized features. Here's a comparison of common wiper blade types:

Conventional Blades: These are the most common and affordable type of wiper blade. They feature a metal frame with multiple pressure points that hold the rubber squeegee against the windshield. Pros: Affordable, readily available. Cons: Can be prone to streaking, particularly at higher speeds; less durable than other options.
Beam Blades: Beam blades feature a one-piece design without an external frame. They distribute pressure more evenly across the windshield, resulting in a cleaner, streak-free wipe. Pros: Excellent performance, durable, aerodynamic. Cons: More expensive than conventional blades.
Hybrid Blades: Hybrid blades combine elements of both conventional and beam blades. They feature a frame for added durability and a sleek, aerodynamic design. Pros: Good performance, durable, aesthetically pleasing. Cons: More expensive than conventional blades.
Winter Blades: Winter blades are designed specifically for use in snowy and icy conditions. They feature a heavier frame and a rubber boot that protects the blade from ice and snow buildup. Pros: Excellent performance in winter conditions. Cons: Can be noisy in dry conditions; not suitable for year-round use.

When selecting aftermarket blades, consider the specific driving conditions and performance requirements. For drivers who frequently encounter heavy rain or snow, beam or hybrid blades may be the best option. For those on a budget, conventional blades can provide adequate performance if properly maintained.

Reliability Aspects and Maintenance Tips

Wiper blade lifespan is heavily influenced by environmental factors and usage patterns. Direct sunlight, extreme temperatures, and abrasive contaminants can all accelerate wear and tear. Here are some maintenance tips to extend the life of your 2017 Sentra's wiper blades:

Regular Cleaning: Clean the wiper blades regularly with a damp cloth to remove dirt, grime, and road debris.
Windshield Cleaning: Keep the windshield clean and free of debris. Use a glass cleaner specifically designed for automotive use.
Avoid Dry Wiping: Never use the wipers on a dry windshield. The friction can damage the rubber squeegee.
Inspect Regularly: Inspect the wiper blades regularly for signs of wear and tear, such as cracks, tears, or hardening.
Replace Annually: As a general rule, replace wiper blades every 6-12 months, or more frequently if needed.
Check Wiper Arm Pressure: Ensure that the wiper arms are applying adequate pressure to the blades. If the blades are streaking even when new, the wiper arms may be weak or worn. The wiper arm can be carefully bent back to apply more pressure, but this is a delicate operation and should only be attempted by a trained professional.

Proper maintenance not only extends the life of the wiper blades but also ensures optimal visibility and safe driving.

Future Trends in Windshield Wiper Technology

The automotive industry is constantly evolving, and windshield wiper technology is no exception. Several emerging trends are poised to shape the future of wiper systems:

Rain-Sensing Wipers: These systems use sensors to detect moisture on the windshield and automatically activate the wipers. The wiper speed is adjusted based on the intensity of the rain.
Heated Wiper Blades: Heated wiper blades prevent ice and snow buildup, improving performance in winter conditions.
Wiperless Systems: Some automakers are exploring wiperless systems that use ultrasonic vibrations or air curtains to remove water and debris from the windshield. These systems offer improved aerodynamics and reduced noise.
Integrated Washer Nozzles: Integrating the washer nozzles directly into the wiper blades ensures that the cleaning fluid is applied precisely where it is needed, maximizing cleaning efficiency.
Smart Wipers: Future wiper systems may incorporate artificial intelligence to predict rain and adjust wiper speed accordingly. These systems could also integrate with navigation systems to anticipate changes in weather conditions.

As autonomous driving technology advances, the importance of reliable and effective windshield wipers will only increase. Autonomous vehicles will rely on sensors and cameras to navigate, and a clear field of vision is essential for these systems to function properly.

Conclusion

Understanding the technical specifications, engineering choices, and performance characteristics of the 2017 Nissan Sentra's windshield wipers is crucial for automotive professionals.
