How to Install a Fallen Rearview Mirror?

If the rearview mirror has fallen off, the installation method is as follows: If it's just the mirror glass that has come off, you can simply reattach it. Below is relevant information about car rearview mirrors: 1. Working Principle: Rearview mirrors have a field of view issue, which refers to the range that the mirror surface can reflect. The industry mentions three key elements of the field of view: the distance between the driver's eyes and the rearview mirror; the size of the rearview mirror; and the curvature radius of the rearview mirror. 2. Design Points: The aspects to consider for rearview mirrors include the obtainable field of view (indirect vision), image distortion, image clarity, image size, the position of the image in the mirror, etc., making it easy to adjust according to changes in the driver's viewpoint. 3. Classification: Rearview mirrors can be divided into three main series: flat mirrors, spherical mirrors, and double-curvature mirrors. There is also another type called the prism mirror, which has a flat surface but a prism-shaped cross-section, typically used as an anti-glare interior rearview mirror.
Last time my rearview mirror fell off, I glued it back myself. The method is quite simple. First, you need to check what type of base the mirror has—most nowadays come with double-sided adhesive pads. Clean off the old adhesive from both the mirror base and windshield using alcohol wipes. Then slightly heat the new adhesive pad with a heat gun or hair dryer (remember to wear gloves to avoid burns). Align it to the original position and press firmly for half a minute to ensure full contact. Here’s the key: after attaching, use tape to reinforce the bond for 24 hours—this makes it more secure. By the way, that area on the windshield is called the "shade point," specifically reserved for mounting rearview mirrors—don’t place it incorrectly and obstruct your view. After installation, readjust the angle before driving to ensure clear rear visibility. During car washes, avoid high-pressure sprays near the mirror base to prolong its lifespan.
There are two types of rearview mirror installation: adhesive-mounted and bolt-mounted. The adhesive type is most common. First, use a utility knife to scrape off residual adhesive marks, being careful not to damage the glass. Purchase specialized double-sided tape from an auto parts store, preferably the black foam type which has three times the adhesive strength of regular tape. Don't apply it directly after removing the protective film - first position the mirror on the glass to mark the spot, ensuring proper alignment. Press firmly to ensure full adhesion, as air bubbles can weaken the bond. The bolt-mounted type is simpler: locate the pre-drilled holes on the roof, align the screw holes and tighten. Be careful not to overtighten the screws, as this may deform or crack the metal base. After installation, check that the vibration-damping sleeve (a plastic component that absorbs road vibrations) is intact. The entire process takes about ten minutes, but since it affects driving safety, never cut corners.
