Replacing the windshield on a 2019 International LT625, which is a heavy-duty commercial truck, is typically a task that should be done by a professional auto glass technician with expertise in handling large vehicles. Here’s a general overview of the process:

1. Assessment: The technician will assess the condition of the existing windshield to determine if it can be repaired or if a full replacement is necessary.

2. Gather Supplies: The necessary supplies are gathered, including the replacement windshield, automotive-grade sealant, and any additional materials or parts needed.

3. Safety Precautions: Safety measures are taken, such as wearing safety glasses, gloves, and other personal protective equipment. Due to the size and weight of commercial trucks, additional safety precautions may be required.

4. Removal of Old Windshield:

   • The old windshield is carefully removed using specialized tools designed to cut through the sealant holding it in place.
   • Care is taken to avoid any damage to the truck’s frame or other components during the removal process.

5. Cleaning and Preparation:

   • The area where the new windshield will be installed is thoroughly cleaned to ensure a proper seal.
   • Any rust, corrosion, or contaminants are addressed to ensure a smooth and secure fit.

6. Installation of New Windshield:

   • The new windshield is positioned and adhered in place using suitable automotive-grade sealant. This sealant creates a waterproof and airtight bond.
   • Excess sealant is typically removed, and the installation is inspected to ensure it’s flush and secure.

7. Curing Time:

   • The sealant requires time to cure and set properly. The curing time can vary depending on the type of sealant used.

8. Clean-Up and Inspection:

   • The technician should inspect the work to ensure there are no issues with the seal, alignment, or any damage to the truck’s exterior or interior.

9. Testing:

   • The new windshield is tested to ensure it is properly sealed, and there are no leaks or issues with visibility.

10. Interior Cleaning: Any debris or dirt that entered the truck’s interior during the replacement is cleaned.

Selecting a reputable auto glass service or technician with experience working on commercial trucks like the International LT625 is crucial. Due to the size and weight of these vehicles, proper installation is vital for the safety and structural integrity of the truck. The technician should also ensure that the replacement windshield is compatible with the specific make and model of the International LT625.
