How Many Drain Holes Does a Car Sunroof Have?

[MirandaRose]

Five drainage holes. Below is relevant knowledge about drainage holes: 1. Water tank drainage hole: Most designs are upwardly inclined, so they may contain substantial water. For safety reasons, such drainage pipes are designed with special channels for water discharge. 2. Door-side drainage hole: Typically located near rubber seals, these appear concealed and may require removal as some windows aren't perfectly sealed, allowing rainwater ingress that can easily clog them. 3. Sunroof drainage outlet: If your sunroof frequently leaks, it's likely due to clogged drainage pipes preventing rainwater discharge, causing water to seep through gaps into the vehicle. 4. Engine drainage hole: This is the most prone to clogging. During rain, if you notice poor drainage, water may spread to the engine compartment, potentially causing starting issues. 5. Condensate drainage hole: Usually positioned below the car's evaporator. Normally, discovering water puddles beneath the vehicle indicates problems with the condensate drainage system.
