Toyota 56121-60100 Windshield Weatherstrip

Removal steps 1. Park on level ground, set parking brake, chock wheels, and wear eye protection and gloves. 2. Assemble common tools and materials: plastic trim tools, flat screwdriver, adhesive remover, lint-free rags, heat source (hair dryer/heat gun), utility knife, replacement weatherstrip, and replacement clips/adhesive as needed. 3. If the work area contains electrical items (power windows/locks or door-mounted airbag wiring), disconnect the negative battery cable and observe the manufacturer-specified wait period before working near airbag components. 4. Remove any trim or moulding that covers the weatherstrip attachment area using plastic trim tools to avoid damage; keep fasteners organized and note their locations. 5. If the weatherstrip is commonly retained by clips, gently pry an end and work the clips free with a trim tool; if it is adhesive-bonded, apply gentle heat to soften the adhesive and peel the strip away slowly; if fasteners are present, remove them. 6. Retain the old weatherstrip as a template, then inspect the mounting flange/channel for corrosion, dents, or old adhesive and remove residue with an appropriate cleaner. 7. Clean and dry the mounting surfaces thoroughly before beginning installation. Installation steps 1. Verify the replacement weatherstrip matches the original shape and length, using the old strip as a template if needed. 2. Replace any broken clips or fasteners; for clip-in types, fit clips to the new strip or vehicle as applicable. 3. If adhesive is required, follow the adhesive manufacturer's directions and apply a thin, even bead to the mounting surface or the strip contact area. 4. Starting at an end or corner, seat the weatherstrip into the channel or onto the flange, pressing evenly to engage clips or bond adhesive; avoid stretching the material while fitting. 5. Trim any excess material cleanly with a sharp knife only where necessary, taking care not to cut into the mounting surface. 6. Reinstall interior trim and moulding, returning fasteners to their original positions. 7. Reconnect the negative battery cable last, and follow any manufacturer guidance if airbag circuits were disturbed. 8. Check the seal by closing the door/panel several times, inspecting for uniform compression and alignment; perform a water or draft test to confirm there are no leaks. 9. If sealing or fit is unsatisfactory, adjust seating, replace faulty clips, or reapply adhesive as required. Repair tip: Mark the original weatherstrip position with painter's tape before removal to speed alignment during installation.
