Best aftermarket replacements

When it's time to replace the wiper blades on your 2019 International LT, several high-quality aftermarket options offer superior performance and durability. Here are some top picks:

• Bosch ICON: (Premium Price Tier) Known for their beam blade technology, Bosch ICON wipers provide excellent all-weather performance and a long lifespan. They utilize a tension spring arc that helps distribute pressure evenly across the windshield.

• Trico Force: (Mid-Range Price Tier) Trico Force blades offer a robust design with a spoiler to help maintain contact with the windshield at higher speeds. Their all-weather performance makes them a reliable choice for commercial vehicles.

• PIAA Si-Tech: (Premium Price Tier) Featuring silicone-infused rubber, PIAA Si-Tech wipers provide a smooth, quiet, and streak-free wipe. The silicone coating also helps to repel water, improving visibility.

Attachment style

The 2019 International LT typically uses a J-hook attachment style for its wiper blades. This is one of the most common and straightforward attachment methods, characterized by a hook-shaped arm that secures the wiper blade in place. While the J-hook is prevalent, it's always a good idea to double-check your specific vehicle's attachment to ensure compatibility, especially as some heavy-duty vehicles can have variations.

How to install

Replacing wiper blades is a relatively simple task that can significantly improve your visibility and safety. For your 2019 International LT, follow these general steps:

1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into an upright position. Be careful not to let it snap back down, as this could damage the windshield.
2. Remove the old blade: Locate the small tab or clip where the wiper blade connects to the arm. Press or lift this tab and slide the old blade off the J-hook. You might need to wiggle it slightly to release it.
3. Attach the new blade: Slide the new wiper blade onto the J-hook, ensuring it clicks securely into place. Give it a gentle tug to confirm it's properly seated.
4. Lower the wiper arm: Carefully lower the wiper arm back onto the windshield. Repeat the process for the other wiper blade.
5. Test the wipers: Turn on your wipers to ensure they are functioning correctly and providing a clean sweep of the windshield. Add some washer fluid to evaluate their performance thoroughly.

Note: While the J-hook is standard, some aftermarket blades may come with multiple adapters. Make sure to use the correct adapter for your vehicle if needed.

When to replace

Wiper blades are wear-and-tear items that should be replaced regularly to maintain optimal visibility and driving safety. A good rule of thumb is to replace them every 6 to 12 months, or at the first signs of wear. Here are some indicators that it's time for new blades:

• Streaking: If your wipers leave lines or streaks of water on the windshield, it means the rubber edge is no longer making proper contact.
• Chattering or skipping: When wipers jump or chatter across the windshield instead of gliding smoothly, it indicates the blade is hardened or uneven.
• Squeaking: A persistent squeaking sound during operation often means the rubber is dry, brittle, or worn out.
• Reduced visibility: Any noticeable decrease in how clear your windshield becomes after a wipe is a clear sign that your blades are past their prime.
• Cracked or torn rubber: Visually inspect the rubber element for any signs of cracking, tearing, or missing pieces.

Don't wait for a downpour to realize your wipers aren't up to the task. Regular inspection and timely replacement will keep you safe on the road.
