Remove the side window glass by unscrewing the two glass screws marked in red circles, then take out the glass. Remove both the inner and outer glass trim strips to facilitate glass removal. After removing the original triangle glass, clean the area where the new triangle glass will be glued. Apply a new layer of glass adhesive following the previous adhesive pattern. Apply white lubricant to the rubber seal of the triangle glass to reduce installation resistance. Install the new triangle glass along the guide rail. After aligning the gaps, secure it with transparent tape, and finally fix the triangle glass fiber guide rail with rivets.

I've replaced the triangular glass a few times, usually the small fixed triangle window on the car door. The process requires tools: prepare a scraper or plastic pry bar to remove old sealant, a pair of thick gloves to protect your hands, and new glass with special automotive glass adhesive. It's best to do this in cool weather to prevent the adhesive from drying too quickly. Steps: First, park the car securely and turn off the engine, remove the door trim panel to expose the glass edges, then slowly pry out the old glass while being careful of flying debris. After cleaning the installation surface thoroughly, apply the adhesive evenly—not too much nor too little—press the new glass firmly in place for 20 minutes to test adhesion. Finally, reattach the trim panel and wait a day for the adhesive to dry before testing for water leaks. Patience is crucial for this job. First attempts might encounter issues like uneven adhesive application or leaks, but practice makes perfect. There are many video tutorials online for reference, saving you hundreds of dollars in repair shop costs.

Last year, the triangular glass on my old car broke, so I decided to try replacing it myself. I bought a new glass panel for just a few dozen bucks, along with a bottle of glass adhesive and a small tool kit. On the day of the repair, I chose a shady spot in the afternoon, wore gloves and safety glasses—safety first. I started by removing the door panel trim from inside the car, located the glass mounting points, and gently pried off the old piece with a pry bar, cleaning the edges thoroughly. Then, I applied the adhesive evenly around the perimeter, making sure not to use too much. I aligned the new glass, pressed it firmly in place, and applied pressure for a while. The whole process took about an hour, requiring patience and attention to detail—rushing could lead to uneven adhesive application and potential leaks. After completion, I had to wait half a day for it to dry before checking the seal by opening the door. Occasionally taking on a DIY challenge not only saves money but also teaches you some automotive knowledge—it feels totally worth it. I recommend giving it a try if you have some free time.

As a beginner, I was quite nervous when replacing the triangular glass, that small triangular window on the front door. The key steps are simple: prepare tools like gloves, a small pry bar, new glass, and sealant; wear protection and remove the interior panel to expose the glass; gently remove the old part, being careful not to injure your hands; clean the frame and apply the sealant evenly; press the new glass firmly and fix it for more than 10 minutes, then test for leaks. If the sealant isn't applied well, it's easy for water to seep in or the glass to loosen. It's recommended to watch a video tutorial first or ask someone experienced for help if it's your first time. Take your time with the whole process, and you can buy an affordable tool set online. Doing it yourself can save you a hundred or two, but safety comes first—don't push yourself if you're not confident.

Safety is the top priority when replacing triangular glass. During the replacement process, I emphasize protection—the glass is fragile with sharp edges, so thick gloves and goggles must be worn, and the car should be parked on a level surface with the handbrake firmly engaged. The process includes removal and installation: first, remove the door panel trim to expose the glass, then carefully pry out the old piece using professional tools to avoid breakage that could harm people or damage the car body. After cleaning the area, apply sealant and press the new glass into place, ensuring even pressure around the edges. Common risks include improper sealant application leading to water leakage and door corrosion, or loose glass installation. A water spray test is mandatory after completion. If tools are incomplete or experience is lacking, accidents are more likely to occur—it’s safer to send the car for professional repair. Life safety is paramount; don’t take unnecessary risks.

Replacing the triangular glass yourself can save costs. For example, OEM parts are expensive, but you can buy aftermarket glass for just a few dozen yuan and adhesive for over ten yuan, getting the job done at a low cost. Tools can be borrowed or purchased as a simple kit online, with the total investment under 50 yuan. Steps include preparation, removing interior trim, taking out the old glass, applying adhesive, installing the new glass, securing it, and testing for leaks—requiring about 2 hours of patient work. Compared to repair shops charging 300-400 yuan, DIY is economical but requires having all the necessary tools like pry bars and adhesive guns. The downside is that first-timers might work slowly or make mistakes leading to leaks, requiring repeated study of video tutorials. In the long run, this skill is practical and can help with other minor repairs, making it ideal for those who enjoy hands-on work.
