Product Description:
Auto radiator heater water hose
OE NO.: 31368405 31319605
Applicable vehicle type: For Vol vo
The automotive radiator hose is a critical fluid transmission component of the engine cooling system, responsible for connecting the radiator, engine water jacket, heater, and expansion tank to form a closed coolant circulation loop.
Core Functions and Importance
1. Efficient Heat Transfer: Conveys excess heat generated by engine combustion to the radiator for dissipation.
2. Pressure Resistance & Leak Prevention: Withstands internal cooling system pressure (typically 0.9-1.5 bar) and potential pressure fluctuations while preventing coolant leakage.
3. Extreme Temperature Resistance: Maintains flexibility and sealing integrity across extreme temperatures from -40°C to +120°C (or higher).
4. Corrosion and Chemical Resistance: Withstands long-term exposure to additives in coolant, engine oil, fuel, and other chemicals.
5. Vibration Damping and Compatibility: Absorbs vibrations between the engine and chassis while connecting components made of different materials (e.g., aluminum radiator and cast iron engine).
Critical Importance: A failed cooling hose can cause rapid coolant loss, leading to severe engine failures like overheating, cylinder scoring, or blown head gaskets—resulting in costly repairs.
