The 2021 International MV is a robust workhorse, and ensuring clear visibility in all conditions is crucial for safety and efficiency. This guide will help you find the right wiper blades for your truck, covering essential information from sizes and attachment types to installation and replacement tips.
Best aftermarket replacements
When it comes to aftermarket wiper blades, several brands offer excellent performance and durability. Here are some top picks:
- Bosch ICON: (Premium Price Tier) Known for their beam blade design, Bosch ICON wipers offer superior performance in all weather conditions, reducing ice and snow build-up.
- Rain-X Latitude Water Repellency: (Mid-Premium Price Tier) These blades feature a special water-repelling coating that helps water bead up and roll off the windshield, improving visibility. Their beam blade design also ensures even pressure distribution.
- Trico Force: (Mid-Range Price Tier) Trico Force blades are designed for strength and durability, featuring a robust, aerodynamic spoiler that helps maintain contact with the windshield at high speeds.
- Michelin Stealth Ultra: (Mid-Range Price Tier) These hybrid blades combine the advantages of conventional and beam wipers, offering excellent all-weather performance and a sleek, low-profile design.
- PIAA Si-Tech: (Premium Price Tier) PIAA Si-Tech wipers feature silicone inserts that provide smooth, streak-free wiping and are known for their long-lasting performance.
Attachment style
The 2021 International MV primarily uses the J-hook attachment style for its wiper blades. This is one of the most common and easiest attachment types to work with. While J-hook is standard for this model, it's always a good idea to double-check your existing blades to confirm, especially if you've recently acquired the vehicle or if aftermarket arms have been installed.
How to install
Replacing your wiper blades is a straightforward process, typically taking only a few minutes per blade. Here are the general steps:
- Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into the upright position.
- Remove the old blade: Most J-hook attachments have a small tab or button on the underside of the wiper blade where it connects to the arm. Press this tab and slide the old blade down and off the J-hook.
- Attach the new blade: Slide the new wiper blade onto the J-hook. You should hear a click when it's securely in place.
- Lower the wiper arm: Carefully lower the wiper arm back onto the windshield. Avoid letting it snap down, as this could damage the windshield.
- Test the wipers: Turn on your wipers to ensure they are functioning correctly and providing a clear view.
For any unusual or less common attachment styles, refer to the instructions provided with your new wiper blades or consult your vehicle's owner's manual.
When to replace
Wiper blades are wear-and-tear items that should be replaced regularly to maintain optimal visibility. As a general rule, you should replace your wiper blades every 6 to 12 months, or at the first signs of wear and tear. Here are some indicators that it's time for new blades:
- Streaking: If your wipers leave streaks or lines across the windshield, the rubber element is likely worn or cracked.
- Chattering: A chattering or skipping sound indicates that the wiper blade is not making consistent contact with the windshield, often due to a hardened or damaged rubber edge.
- Squeaking: While sometimes caused by a dirty windshield, persistent squeaking can also point to worn out or improperly installed wiper blades.
- Reduced visibility: If you notice that your wipers are no longer clearing the windshield effectively, especially in rain or snow, it's definitely time for a replacement.
Regular replacement not only improves visibility but also prevents potential damage to your windshield from worn rubber blades.
