Signs Your Coolant Overflow Hose Needs Replacement:
Coolant puddle under the vehicle (typically near the front or passenger side)
Low coolant warning light illuminated on dashboard
Visible cracks, splits, or bulging on the hose surface
White or green crystallized around hose connections
Hose feels hard, brittle, or swollen when squeezed
Soft spots or mushy areas on the hose (internal degradation)
Coolant smell (sweet odor) from engine bay
Engine temperature running higher than normal
Coolant level drops repeatedly despite no visible external leak
Hose connection points are weeping or dripping

Why Do Audi Q5 Coolant Hoses Fail?
The 2.0L TFSI engine in the Audi Q5 operates at high temperatures and pressures. Over time (typically 5-8 years or 60,000-100,000 miles), the rubber coolant hoses degrade due to:
Constant heat cycling (expansion and contraction)
Pressure stress from the pressurized cooling system
Vibration fatigue from engine operation
The overflow hose is particularly vulnerable because it handles both pressure and vacuum cycles as the system heats and cools.
