How to Unclog the Sunroof Drain Pipe of a Geely Emgrand?
2 Answers
After clogging occurs, you can find a 6mm iron wire (usually clogged by dust and mud), then poke open the four drain holes, and pour water from above until water drains out. Aim an air gun at the two front drain holes inside the sunroof and use high-pressure airflow to blow through the drain pipe. Flushing the drain pipe with a syringe should be able to clear the pipe. First, use a syringe to extract the water from the sunroof drain channel to prevent water from flowing into the car through the sunroof drain channel.
I have experience with the Geely Emgrand sunroof drain tube issue. First, locate the drain holes - there are coin-sized openings at each of the four corners of the sunroof. Use thin wire or bicycle brake cable to gently clear them, but don't push too hard or you might puncture the soft tube. Test the drainage with a bottle of mineral water - if water flows quickly to the ground near the front wheels, it's clear. Avoid parking under trees as fallen leaves can clog it faster. I clean the track dust quarterly. If completely blocked, don't force it - the tube connectors are behind the A-pillar trim, and breaking the clips makes things worse. I recommend spending about 50 yuan at a repair shop. If doing it yourself, wear gloves - the sludge inside is black and smelly. Remember to wash your hands afterward.
