It takes 12 hours to replace the front windshield at a 4S store. Here are the relevant details: 1. Windshield: It is adhered to the car body with glass adhesive. Since the adhesive takes a long time to cure (usually more than 12 hours at room temperature), the car should not be moved until the adhesive is completely dry after replacing the windshield. This prevents issues such as glass misalignment, adhesive failure, or water leakage due to insufficient curing. 2. Precautions: Avoid washing the car for three days after replacing the windshield. Remove the tape securing the windshield position after three days. Try to avoid driving on excessively bumpy roads and refrain from sudden braking or rapid acceleration to prevent windshield displacement. Do not insert parking permits or other cards into the gap between the front windshield and the dashboard.

I remember when I last replaced the windshield at the 4S dealership, the whole process took me most of the day, about two hours in total. I arrived at 10 a.m. that morning, and they first inspected the car's condition, then spent twenty minutes removing the old glass and cleaning off the adhesive residue. Installing the new windshield was the most time-consuming part, as they had to carefully align it and ensure the sealant was applied evenly. After installation, the staff mentioned the adhesive needed at least half an hour to an hour to harden before I could drive the car away, otherwise it might leak or become loose. They suggested I either wait at the dealership or come back in the afternoon to pick up the car. At that time, there weren’t many customers, so they worked quite efficiently, but if there were other repair jobs in line, the process could take longer. Nowadays, I always book an appointment in advance and choose off-peak hours to save a lot of waiting time. Overall, in most cases, getting it done within 2-3 hours is the norm.

I've visited 4S shops several times to replace glass on my new energy vehicle, and the timing was quite flexible. The last replacement took only about an hour and a half, with the removal and installation done quickly, mainly because the new adhesive hardens faster than traditional glue. However, post-installation testing and inspection are crucial, and the staff must confirm everything is correct before you can drive away. I chatted with the staff, and they said the replacement time depends on the vehicle type: regular sedans have flat glass and can be installed in half an hour; SUVs or advanced models with sensors take an extra hour because things like wiper sensors need recalibration. I recommend calling ahead to check the shop's workload and avoiding weekend peaks if possible. It's a good idea to bring something to pass the time or have the staff notify you when the car is ready. On average, completing the job within 1-2 hours is ideal.

As a father of two, I'm particularly sensitive to this type of repair time. Last time I took my kids to the 4S shop for window replacement, it took nearly two hours after the appointment. During the replacement process, they prioritized safety: removing the glass slowly to avoid injury from fragments, and waiting long enough for the adhesive to cure properly before releasing the vehicle. They explained that the adhesive requires sufficient time to fully harden, sometimes advising against driving at high speeds immediately after leaving the shop to ensure firm bonding. I think an average of 1-3 hours is reasonable, depending on the vehicle's age and the 4S shop's staffing. New parents should plan their time wisely to prevent kids from getting bored, or simply leave the car at the shop and pick it up in the afternoon. These safety details are crucial – don't compromise them to save time.

I have extensive experience in car repairs, especially with windshield replacements. At a 4S shop, the replacement process typically takes between 1.5 to 3 hours. Several factors contribute to this: removing the old glass requires careful handling; installing and aligning the new windshield is crucial and takes about 40 minutes; the most tedious part is waiting 45-60 minutes for the adhesive to cure. The type of glass also affects the time: standard windshields are quicker, while those with heating elements or sensors take significantly longer. I recommend checking with the 4S shop about their busy periods—avoiding early mornings can reduce wait times. On average, the whole process takes around two hours, so I often advise friends to bring some reading material while they wait.
