The sunroof drain holes on the Baojun 730 are located in the four corners of the sunroof. They are easily visible when the sunroof is opened. Below is an introduction to the function of the sunroof drain holes and maintenance precautions. Function of the sunroof drain holes: The sunroof drain holes are designed to prevent rainwater from entering the cabin. This structure is present in all models equipped with a sunroof, but it requires regular maintenance. The sealing strips around the drain holes should also be replaced once a year. Maintenance precautions for the sunroof drain holes: Inspect the sunroof tracks at least once a year. Fully open the sunroof and check for any dirt or debris in or around the tracks. After cleaning, lubricate the sunroof tracks with grease to prevent rust and ensure smooth operation of the sunroof.
Seeing many people asking about the location of the sunroof drain holes on the Baojun 730, let me share some practical tips. The front drain holes are located at the corners on both sides of the windshield—just lift the A-pillar trim panel and you'll spot two small round holes where leaves and debris tend to clog. The rear drain holes are a bit more hidden; you'll need to remove the rear trunk trim panel near the inner side of the taillights to feel the rubber tube ends with your fingers. If you're doing it yourself, avoid using wire to poke forcefully as it can puncture the hose. I prefer using a bicycle brake cable to gently clear the blockage, followed by flushing with warm water using a syringe—it works wonders. Cleaning them once before the rainy season usually prevents flooding.
Last time I helped my uncle deal with the 730 sunroof leaking issue, I got very familiar with the drainage holes. The front drainage holes are located under the plastic cover at the top of the A-pillars, symmetrical on both sides. The rear drainage holes require removing the rear wheel arch liners and are tucked away in the inner corners of the C-pillars. Important reminder: The drainage tubes on this car are particularly prone to kinking at the B-pillar bends, so be gentle when using an air gun to blow them out. In summer, I make it a habit to check every three months, using a fish tank water change hose connected to a mineral water bottle to flush them twice. If you notice water seeping into the carpet, don't panic—it's most likely a loose connector, and you can just press the clip tight yourself.
