Where are the sunroof drainage holes located on the Renault Koleos?
2 Answers
The sunroof drainage outlets on the Koleos are positioned at all four corners of the sunroof. Rainwater is channeled out through these outlets along the A-pillars and C-pillars of the vehicle. Below is additional information: 1. Consequences of clogged sunroof drainage holes: Although the sunroof is installed on the upper part of the roof and sealed with rubber strips against the upper metal panel, water can still seep through the gaps in the rubber strips and flow to the lower part of the sunroof. If the drainage holes are clogged at this time, accumulated water may flow from the sunroof's fixed guide channels into the vehicle's cabin, with the most noticeable sign being water stains on the roof lining. 2. Inspection guidance: If the sunroof leaks, check whether the drainage outlets are blocked by dust. For routine maintenance of the car sunroof, there are no special requirements other than periodically inspecting the surrounding rubber seals for any damage and checking the lubrication condition of the tracks.
I've been driving a Renault Koleos for several years, and the location of the sunroof drain holes is actually quite common. The front ones are inside the A-pillars near the windshield—just look up and you'll spot them. The rear ones are near the C-pillars, close to the corners of the rear. I remember one summer after a heavy rainstorm, the car's carpet got soaked. Upon inspection, I found the drain holes were clogged with small leaves. Cleaning them requires patience—just gently push the debris out with a small stick, and they'll flow smoothly again. These holes play a crucial role. If drainage is blocked, rainwater can leak into the car, damaging not only the interior but also causing electrical shorts or overheating. I recommend flushing the openings with a thin tube during seasonal car washes to keep them clear. If you park under trees, it's best to regularly sweep away fallen leaves. This way, you can avoid unnecessary trouble and drive with peace of mind.
