2017 Nissan Titan Wiper Blade Size

The 2017 Nissan Titan, a robust and capable pickup truck, relies on a seemingly simple component for driver safety: the windshield wiper blades. While often overlooked, the correct wiper blade size is critical for maintaining clear visibility in inclement weather. This guide delves into the specifics of the 2017 Titan's wiper blade requirements, exploring not just the size but also the implications of choosing the right (or wrong) blade.

Understanding Wiper Blade Specifications for the 2017 Titan

For the 2017 Nissan Titan, the recommended windshield wiper blade sizes are as follows:

Driver Side: 26 inches
Passenger Side: 20 inches

These measurements are crucial. Deviation from these sizes, even by a small margin, can negatively impact performance and potentially damage the wiper mechanism.

Why Specific Sizes Matter

The specified sizes aren't arbitrary; they are carefully engineered to ensure optimal coverage of the windshield. Several factors contribute to this selection:

Windshield Curvature: The 2017 Titan's windshield has a specific curvature. Blades that are too long may not conform properly to the glass, leading to streaks and uneven wiping. Conversely, blades that are too short will leave portions of the windshield unwiped, reducing visibility.
Wiper Arm Geometry: The design of the wiper arms dictates the arc of the blades' movement. The specified blade lengths are designed to maximize the wiped area within this arc. Incorrect lengths can cause the blades to overextend or underreach, potentially hitting the A-pillars or leaving a large unwiped zone.
Motor Load: The wiper motor is designed to handle a specific load. Using significantly larger blades increases the load on the motor, potentially leading to premature wear and failure. Smaller blades, while reducing the load, compromise visibility.
Aerodynamic Considerations: While less significant than the above points, the blade length contributes to the aerodynamic profile of the vehicle, particularly at highway speeds. Excessively long blades could create unwanted turbulence and noise.

Consequences of Incorrect Wiper Blade Size

Using wiper blades that deviate from the recommended sizes can lead to a cascade of problems:

Streaking and Uneven Wiping: As mentioned earlier, incorrect curvature contact leads to streaking, severely hindering visibility.
Noise: Blades that are too long can vibrate excessively, creating distracting noise, especially at higher speeds. They may also impact the windshield frame, causing further noise and potential damage.
Damage to Wiper Arms: Blades that are too long or too short can put undue stress on the wiper arms, potentially bending or breaking them. Replacing wiper arms is a more significant and costly repair than simply replacing the blades.
Motor Failure: Overloading the wiper motor can shorten its lifespan. A burnt-out wiper motor requires professional replacement.
Reduced Visibility: Ultimately, the primary consequence of using incorrect wiper blades is reduced visibility, increasing the risk of accidents, especially in adverse weather conditions.

Factors to Consider When Choosing Replacement Blades

While adhering to the specified size is paramount, other factors influence the overall performance and longevity of wiper blades. These include:

Blade Material: Wiper blades are typically made from rubber or silicone. Silicone blades generally offer better performance and durability but come at a higher price point. Rubber blades are a more economical option but may require more frequent replacement.
Blade Design: Several blade designs are available, including conventional, beam, and hybrid blades. Beam blades are generally considered superior due to their frameless design, which provides more uniform pressure distribution across the windshield. This leads to better wiping performance and reduced streaking. Hybrid blades offer a compromise between conventional and beam designs, combining the features of both.
Weather Conditions: Consider the typical weather conditions in your area. If you frequently encounter heavy rain, snow, or ice, opt for blades designed to handle these conditions. Some blades feature specialized coatings or designs to prevent ice buildup or improve wiping performance in heavy rain.
Brand Reputation: Choose reputable brands known for producing high-quality wiper blades. Reading online reviews and comparing different brands can help you make an informed decision.
Price: While price shouldn't be the sole determining factor, it's essential to consider your budget. Balance the cost with the desired performance and durability.

Installation Tips

Installing wiper blades is a relatively straightforward process, but following these tips can ensure a successful and safe installation:

Refer to the Owner's Manual: Consult your 2017 Nissan Titan's owner's manual for specific instructions on wiper blade replacement.
Protect the Windshield: Before removing the old blades, place a soft cloth or towel on the windshield to prevent damage if the wiper arm accidentally snaps back.
Understand the Attachment Mechanism: Wiper blades typically attach to the wiper arms using one of several common mechanisms, such as a J-hook, pin, or side-lock. Familiarize yourself with the attachment type on your Titan.
Properly Seat the New Blade: Ensure the new blade is securely seated in the wiper arm. A loose blade can detach during operation, posing a safety hazard.
Test the Blades: After installation, test the new blades by spraying the windshield with washer fluid and running the wipers. Check for streaking or uneven wiping.

Troubleshooting Common Wiper Blade Problems

Even with the correct size and proper installation, wiper blades can sometimes exhibit problems. Here are some common issues and their potential solutions:

Streaking: Streaking can be caused by worn blades, a dirty windshield, or contamination on the blades. Clean the windshield thoroughly and inspect the blades for damage or debris. If the blades are worn, replace them.
Chattering: Chattering occurs when the blades skip or vibrate across the windshield. This can be caused by a dry windshield, worn blades, or a bent wiper arm. Ensure the windshield is wet when operating the wipers and inspect the wiper arms for damage.
Smearing: Smearing indicates that the blades are spreading dirt or debris across the windshield rather than wiping it away. This is often caused by oily residue on the windshield. Clean the windshield with a glass cleaner specifically designed for automotive use.
Noisy Operation: Noisy operation can be caused by worn blades, a dry windshield, or a loose wiper arm. Replace the blades if they are worn and ensure the wiper arms are properly tightened.

Conclusion

Maintaining clear visibility is paramount for safe driving, and the 2017 Nissan Titan's wiper blades play a critical role in achieving this. By understanding the importance of using the correct wiper blade size (26 inches for the driver side and 20 inches for the passenger side), selecting high-quality replacement blades, and performing regular maintenance, you can ensure optimal wiper performance and enhance your driving safety.

Remember, regular inspection and timely replacement of wiper blades are essential preventative maintenance steps. Don't wait until visibility is severely compromised before addressing worn or damaged blades.
