Womala Engine Output Hose Oil Cooler Water Pipe OE 30774514 for Volvo Auto Parts

Core Functions

• Facilitate Coolant Recirculation: Transports coolant from the engine oil cooler back to the main cooling system (radiator/reservoir), completing the coolant loop. This ensures the oil cooler always has a fresh supply of cooled coolant to absorb oil heat, maintaining engine oil at an optimal operating temperature (typically 80–110°C).
• Withstand Under-Hood Stress: The multi-layered construction resists chemical degradation (from coolant/oil), high temperatures (from engine and exhaust), and physical wear (from vibration or debris), preventing hose cracking, swelling, or rupture—failures that would disable the oil cooler and lead to oil overheating.
• Maintain System Pressure: The reinforcement layer prevents the hose from collapsing under vacuum or expanding under pressure, ensuring consistent coolant flow rate. Stable flow is critical for the oil cooler to function efficiently: insufficient flow leads to inadequate oil cooling, while excessive flow wastes energy from the water pump.
