How to Replace the Sunroof Drain Tube on a Ford Focus?
4 Answers
First, pry off the right-side panel on the passenger side dashboard. Remove the internal Torx screws, then pull outward by hand. After releasing the three snap fasteners, lift upward. Remove the screws securing the sun visor and sunroof handle. Take out the old drain tube and its clips. Install the new tube and firmly press the black connector into place by hand.
Last time I replaced the drainage pipes for the Ford Focus sunroof myself, here are some practical tips to share. First, remove the A-pillar trim and sun visor, carefully prying open the clips with a plastic pry tool. The old drainage pipes are usually tucked inside the headliner layer—trace and locate all four pipes (front and rear). During removal, pay special attention to the sections where the pipes connect to the sunroof tray, as they’re prone to aging and cracking. For replacements, use OEM 8mm-diameter soft rubber tubing, lubricate the joints with silicone grease before securing them tightly. Finally, don’t forget to test: slowly pour water into the sunroof’s drainage channel and check if it flows smoothly out near the wheel wells. The whole process takes about two hours—if you’re not confident in your DIY skills, better hire a pro, as the headliner clips are extremely fragile.
Don't rush to dismantle the roof when dealing with sunroof drain pipes! The most prone clogging spots on a Ford Focus are both ends of the pipes. First, inspect the water inlets at the sunroof corners and use thin wire to clear leaves and debris. Then check the drainage outlets underneath – crouch down to locate four small black rubber tips, usually near the rear wheel fenders. Pinch the pipe ends to remove the rubber caps and use an air gun to blow through from above. If the pipe is truly damaged, here's a clever trick: cut off the damaged section, sleeve both ends with a 5cm-long 8mm copper pipe connector, then wrap with waterproof tape. This method is much easier than replacing the entire pipe – tested and proven effective.
As a Ford mechanic with ten years of experience, replacing the Focus drain hose requires four steps. First, remove the A-pillar upper trim, then unscrew the sun visor screws, followed by loosening the dome light assembly. Use only a T20 screwdriver and plastic pry tools throughout the process, as metal tools may scratch the interior. The OEM drain hose is a corrugated rubber hose - when purchasing replacements, verify the part number 8M5Z-78519A58. Pay special attention during installation: the front drain hose measures 92cm and the rear one 87cm, leaving 5cm extra length to prevent tension. The most critical step is testing drainage speed after reassembly - 500ml of water should drain completely within 8 seconds to meet specifications.
