What should be noted when replacing the front windshield?
3 Answers
When replacing the front windshield, pay attention to the following: 1. Do not wash the car within three days after replacing the windshield, and remove the tape securing the windshield position after three days. 2. Try to avoid driving on excessively bumpy roads, and refrain from sudden braking or rapid acceleration to prevent the windshield from shifting. 3. Do not insert parking permits or other cards into the gap between the front windshield and the dashboard. Additional tips: During regular glass maintenance, choose the appropriate windshield washer fluid based on the season and weather conditions. 1. When the windshield surface appears blurry, cleaning it with suitable washer fluid can make it much clearer. 2. If you notice excessive glare on the glass at night, you can also wipe it with washer fluid. 3. When driving on highways or in dusty conditions, washer fluid is used up quickly, so remember to refill it promptly.
I've got quite some experience with windshield replacement, so let me share a few tips. Always go to a reputable shop for replacement – those cheap roadside stalls often cause issues, like poor sealing leading to water leaks, which is a real headache. After the glass is installed, the adhesive needs at least 24 hours to fully cure. Avoid driving or washing the car during this period – I learned the hard way when I drove too soon and the adhesive shifted. Many modern cars come with rain sensors or cameras, so after installing a new windshield, recalibration is a must. Skipping this step might disable safety features like collision avoidance. Before installation, make sure the technician thoroughly cleans off old adhesive residue to prevent bubbles that could compromise the seal. Cost-wise, if you have glass coverage, file an insurance claim first. Without insurance, opt for reliable big brands – safety comes first. During the curing period, using the AC in recirculation mode to reduce humidity is safer, and parking indoors is ideal to avoid sunlight damaging the adhesive.
From a technical perspective, there are many considerations when replacing windshield glass. Using high-quality polyurethane adhesive for glass installation is crucial to ensure strong sealing—avoid materials from small workshops. After replacement, ADAS system calibration is mandatory, as rain sensors or onboard cameras have a high risk of false alarms. I recommend visiting a 4S dealership for professional equipment handling. During installation, thoroughly remove old glass residue and ensure the bonding surface is clean to prevent loosening or water leakage. During the drying period, it's advisable to use the car's air conditioning for dehumidification to help the adhesive cure faster and more evenly. Checking for uniform adhesive lines without bubbles is essential—use a flashlight to inspect the edges for smoothness. For models with heating functions, test the heating wires post-replacement to ensure proper operation. The entire process takes about half a day, but avoid high-speed driving for the following week to minimize wind pressure impact.
