What to Do If the Radar Hole Is Too Large?

Although the hole is large, the surface of the probe can be covered. Wrap the cylindrical part with electrical tape multiple times to match the size of the hole. If the surface of the probe cannot cover the hole, you can purchase a 28mm silicone sleeve.
I once encountered a situation where the radar hole was too large. It happened after a modification when the hole positions didn't align, causing the radar to shake unsteadily and trigger false alarms, which really startled me. I had to find a way to secure it. I tried filling the gaps with hot melt glue or rubber spacers—cheap and easy to get, and something I could do myself. Remember to check if the radar is properly aligned; otherwise, it could affect detection accuracy, and rainwater might accumulate and damage the sensor. This method is simple, but be careful not to block the signal. Always pay attention to warning lights while driving to prevent accidents. If it's too tricky, it's best to have a professional shop adjust or replace the hole fittings. Safety first—don't cut corners.
Enlarging the radar hole poses significant risks. My experience shows that an oversized hole can cause sensor loosening, leading to frequent false alarms or failures during reversing, which can easily trigger accidents. Immediate action is required: first, test the radar function. If noticeable wobbling occurs, temporarily seal it with epoxy resin to reinforce the hole edges. The long-term solution is to replace the hole bracket or opt for professional calibration. Don’t skimp on this—repair costs are usually low, but delaying may result in part scrappage or increased repair expenses. Never overlook minor issues during routine maintenance; ensuring driving safety is the top priority.
The hole was enlarged, so I tried fixing it myself first. I looked for tools like sandpaper to smooth the edges or added anti-vibration pads to secure the radar. The materials cost just a few dozen yuan online. The DIY process was fun, but be mindful of calibration accuracy to avoid false alarms. After a quick fix, the detection capability was restored. Sharing this experience—DIY is enjoyable but know your limits. Done right, it saves both money and time.
