Womala Heater Hose 31368661 Water Pump Hose for Auto Parts S60 V60 XC60

Core Functions

• Cabin Heating Support: Transports hot engine coolant from the water pump to the heater core. The vehicle’s HVAC system blows air over the heated core, converting it to warm air for the cabin—critical for defrosting and passenger comfort in cold weather.
• Coolant Circulation: Acts as a supplementary channel for coolant flow, helping distribute heat evenly across the engine and maintaining the cooling system’s overall efficiency (especially during low-engine-load conditions).
• Leak Prevention: Forms a tight seal with connected components (via clamps) to retain coolant. Even small leaks can reduce heating performance, lower coolant levels, and risk engine overheating.
