Weatherstrip Seal

Auto Installation 101: Attaching a New Weatherstrip Seal

Are your car’s doors starting to leak or rattle? Then it’s time to strip off the old weatherstrip seal and install a new one. This often-forgotten component is responsible for providing an air-tight seal while the doors are closed. Once this part wears out, the doors might feel a bit loose, and air and water can easily get inside the cabin. So once you experience these signs, get your hands on a new seal and attach it as soon as possible. Here’s how:

Required skill level: Novice

Tools you’ll need:

1. Screwdriver
2. Seal adhesive
3. Weatherstripping remover
4. Water hose or sandpaper

Inspecting the replacement weatherstrip seal

Before you start with the actual installation, it’s best to take a closer look at the new seal. Make sure it’s the same as the old one. The new one should have the same thickness, shape, and holes as the old seal.

Removing the old seal

Using a screwdriver, you might need to remove screws in order to remove the worn-out seal. Once the screws are removed, gently peel off the old weatherstrip. For hard-to-remove bits, spray them with some weatherstripping remover first. Then once the weatherstrip softens, peel it off again and see if all the bits are removed. You can use the screwdriver to gently pry off any remaining strips. For leftover adhesives, spray them with some weatherstripping remover. Wait for the glue bits to soften up. Then remove them with a screwdriver.

Prepping the new seal

Once you’ve removed every bit of the old seal and glue, place the new seal onto the frame. Check if the new seal fits perfectly around the frame’s contour. Then remove it. Before attaching it, clean it with sandpaper or rinse it with water. This is to make sure that the new weatherstrip doesn’t contain any contaminants or rough spots.

Installing the new weatherstrip

Sparingly apply adhesive on the new weatherstrip’s back side. Then attach it onto the frame before the glue dries up. Make sure that the new seal snugly fits every nook and cranny of the frame. Then re-install any screws you’ve previously removed.

Your car's windshield is built in such a way that it allows you to drive through rainy days and harsh weather elements without worrying about rain getting into your car. That's why it comes with a weatherstrip seal, a part that keeps rain and other tiny debris outside your vehicle . If you need a new one, keep in mind that basic knowledge of the different types of weatherstripping is necessary in choosing a weatherstrip seal that fits your car.

Weatherstrippings, or weather strip seals, can be classified into two different categories: one based on grooves and the other based on the material. Below is a brief description of the two and how each type is an advantage or a disadvantage to your vehicle.

• Based on groove - A "channel" or a groove is present in all windshield weatherstrippings. It allows the seals to fit firmly between the windshield glass and the windshield frame. Two types of windshield weatherstripping are available in the market. The first type is the universal windshield weatherstrip seal. It is one long piece of rubber seal that you need to cut to fit your windshield. The second type is the custom windshield weatherstrip seal. It is a closed loop of rubber seal that's pre-measured to fit your particular car model. If you want easier installation, go for a customized seal.
• Based on material - Windshield weatherstrip seals are also identified based on the material they're made of. Some windshield weatherstrip seals contain rubber and certain fibers to provide flexibility and maintain shape. In higher-quality weatherstrip seals, there's also a coating which further protects the seals from UV rays. The acronyms EDPM, TPE, or TPO are usually displayed in product info labels, pertaining to the main rubber blends used. If you live in a sunny place, seals with UV protection are your best bet.

Though your weatherstrip seal type choices are limited to two, it is still important to take certain factors into consideration. These factors include your car model and year, and the type of weatherstripping suited for windshields. Remember that weatherstrip seals for car doors and windows might not fit the windshield. Attaching the wrong type of seal can lead to leaks, drafts, rattling, and loosening of the windshield glass. Given that windshield replacement digs a large hole in your pocket, make sure that you only get weatherstrip seals designed for windshields.

Your car survives rain and other weather conditions because of a part called the weatherstrip seal. From the name itself, it prevents weather elements from entering your vehicle. Over time, your car's weatherstrip seal will eventually crack or get damaged. Replacing weatherstrip seals is an easy task for beginners and experts alike. With a few simple tools and a bit of patience, you can finish the repair in no time.

Get started with these simple yet concise instructions:

• Soap
• Glass cleaner
• Clean piece of cloth or paper towel
• Weatherstripping removal tool
• Weatherstripping adhesive
• Plastic putty knife
• Tape measure
• Wrench
• New weatherstrip seal

Step 1: Start with removing your windshield's old weatherstrip seal. Clean the windshield with a glass cleaner. Use a clean cloth or paper towel to wipe off dirt and debris.

Step 2: Raise each wiper arm away from the windshield until it locks in a vertical position. Use a wrench to remove the wiper blade nuts and washers. Set the wiper arms side.

Step 3: Wedge the tip of the weatherstripping removal tool between the windshield and the trim. Work the tool around the entire perimeter of the windshield.

Step 4: Put the new weatherstrip seal by pressing it over the edge of the windshield. Use your thumb to push it down and secure it into place. Align or realign the new weatherstrip seal using the weatherstripping removal tool.

Step 5: Next, proceed to your car doors and windows. Open the doors and roll down the windows. Remove the old weatherstrip seals with a weatherstripping removal tool. Begin with one corner and work around the perimeter of the door.

Step 6: Do the same with the other doors and windows. Get rid of the remaining weatherstrip seal with a plastic putty knife. Clean the bare door and window edges with soap and cloth. Scrub the edges if there's old adhesive left.

Step 7: Take a measuring tape and determine your door and window sizes. Use a utility knife and cut the weatherstrip seal to fit around your doors and windows.

Step 8: Put beads of weatherstrip adhesive around the entire perimeter of the first window you decide to work on. Again, use your thumb to press the weatherstrip seal firmly on the adhesive. Repeat the same procedure to the remaining doors and windows.
