Finding the right windshield wipers for your 2018 Nissan Altima is crucial for maintaining clear visibility and ensuring road safety. Incorrectly sized wipers can lead to streaking, incomplete cleaning, and even damage to your windshield. This guide will help you determine the correct wiper sizes and answer common questions about replacing them.
What are the correct 2018 Nissan Altima windshield wiper sizes?
The 2018 Nissan Altima typically requires two different sized wipers. While the exact dimensions can vary slightly depending on trim level and options, the most common sizes are:
- Driver's Side (Longer Wiper): 26 inches
- Passenger Side (Shorter Wiper): 16 inches
Important Note: Always double-check your owner's manual for the precise wiper blade sizes recommended for your specific 2018 Nissan Altima model. The information above represents the most commonly reported sizes but may not be universal.
Where can I find the wiper size information in my owner's manual?
Your owner's manual should have a section dedicated to maintenance, which will include specifications for replacing your windshield wipers. Look for a diagram showing the wiper arm locations and the corresponding blade sizes. If you cannot locate your owner's manual, you can often download a digital version from the Nissan website using your Vehicle Identification Number (VIN).
What type of wiper blades should I use for my 2018 Nissan Altima?
While size is crucial, the type of wiper blade is equally important. Modern vehicles often benefit from:
- Beam Blades: These blades have a single, aerodynamic element that distributes pressure evenly across the windshield. They tend to offer superior cleaning performance and longer lifespan compared to conventional wiper blades.
- Hybrid Blades: These combine features of both conventional and beam blades.
Consider the climate you live in when choosing blade type. Beam blades are often a better option in areas with harsh weather conditions, while hybrid blades offer a balance of performance and affordability. You can find a wide variety of options from reputable automotive parts stores.
How often should I replace my 2018 Nissan Altima windshield wipers?
Generally, you should replace your windshield wipers every six to twelve months, or more frequently if you notice streaking, chattering, or incomplete cleaning. Harsh weather conditions like snow, ice, and extreme heat can significantly reduce the lifespan of your wipers. Regular inspection is key to maintaining optimal visibility.
Can I use universal wiper blades on my 2018 Nissan Altima?
While some universal wiper blades might fit, it's strongly recommended to use wiper blades specifically designed for your 2018 Nissan Altima or at least ones that match the dimensions mentioned above. Using incorrectly sized or designed blades could lead to poor cleaning, damage to your windshield, or even wiper arm malfunction.
What happens if I use the wrong size windshield wipers?
Using incorrect wiper sizes can result in several problems:
- Streaking and incomplete cleaning: The wipers won't make proper contact with the windshield, leaving streaks and dirt behind.
- Windshield damage: Improper pressure or contact can scratch the windshield over time.
- Wiper arm damage: The wrong size can put excessive stress on the wiper arms, potentially causing damage or breakage.
- Reduced visibility: The primary function of wipers is compromised, significantly impacting driving safety.
By following this guide and consulting your owner's manual, you can ensure you select the correct 2018 Nissan Altima windshield wiper size and type, keeping you safe and enjoying optimal visibility on the road. Remember, regular wiper maintenance is a small step with a big impact on your driving experience.
