Attachment style

The 2018 International LT primarily uses a J-hook attachment style for its wiper blades. This is one of the most common and easiest attachment types to work with, making replacements straightforward. Always double-check the attachment style when purchasing new blades to ensure compatibility.

How to install

Replacing wiper blades is a simple maintenance task that most owners can perform themselves. For the J-hook attachment on your International LT, follow these general steps:

1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into a raised position. Be careful not to let it snap back against the glass.
2. Remove the old blade: Locate the small tab or clip where the blade connects to the arm. Press or lift this tab and slide the old blade off the J-hook. It might require a little wiggling.
3. Attach the new blade: Slide the new wiper blade onto the J-hook, ensuring that the hook passes through the designated slot on the blade. You should hear a click or feel it lock into place.
4. Secure the blade: Gently pull on the new blade to confirm it's securely attached.
5. Return the wiper arm: Carefully lower the wiper arm back onto the windshield.
6. Test: Turn on your wipers to ensure they are functioning correctly and providing a clear view.

Note: While the J-hook is standard for the 2018 International LT, 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 perishable components and should be replaced regularly to maintain optimal visibility and safety. Here are some signs it's time for new blades:

• Timeframe: As a general rule, replace your wiper blades every 6 to 12 months, even if they appear to be working fine. Over time, sunlight, ozone, and road grime degrade the rubber.
• Streaking: If your wipers leave streaks across the windshield, it's a clear sign the rubber has worn down or hardened.
• Chattering or skipping: Wipers that chatter, skip, or squeak indicate the blade is not making consistent contact with the windshield, often due to a hardened or torn rubber edge.
• Reduced visibility: If you find yourself struggling to see clearly during rain or snow, your wiper blades are likely no longer effective.
