Engine coolant hose Coolant pump hose OE 30774512 Thermostat return hose for VO LVO
Product Description:
Radiator coolant pipe
OE NO.: 30774512 30774513
Applicable vehicle type: For VO LVO
The Thermostat Return Hose is a critical component within the engine cooling system, forming part of the coolant circuit that connects the thermostat to the radiator. Its function is to guide coolant flowing from the thermostat back to the radiator for heat dissipation. Typically constructed as a hose, it comprises multiple layers of rubber and reinforcing materials, including an outer weather-resistant rubber protective layer, an intermediate high-strength fibre reinforcement layer, and an inner corrosion-resistant rubber layer.
The thermostat return coolant hose offers the following technical advantages:
- Multi-layer composite structure design: Employing a multi-layer composite structure comprising an inner coolant-resistant rubber layer, an intermediate reinforced fibre layer, and an outer weather-resistant rubber layer, it achieves comprehensive performance in high-temperature resistance, high-pressure resistance, and corrosion resistance.
- Precision moulding process: Utilising advanced rubber extrusion and compression moulding techniques, combined with precise mould design, ensures dimensional accuracy and shape consistency of the hose. This enables precise matching with thermostat and radiator interfaces, preventing installation difficulties or leakage issues caused by dimensional deviations.
- Reliable Sealed Connections: Metal fittings at both ends undergo special vulcanisation to form a tight bond with the rubber body. Surface sealing treatment ensures zero leakage at interfaces with thermostat and radiator coolant ports. This robust connection enhances cooling system sealing integrity and efficiency.
- Advanced Material Formulation: Specialised rubber compounds resistant to high temperatures, oils, and ageing are selected. Additives such as antioxidants and UV inhibitors are incorporated to optimise the formulation, meeting the demanding operating conditions of cooling systems.
- Stringent Quality Control: Each hose undergoes pressure testing, leakage testing, and endurance testing during production to ensure compliance with rigorous quality standards.
- Customisable Manufacturing: Hoses can be tailored for specific vehicle models and engines, accommodating variations in length, internal diameter, external diameter, and fitting configurations. This customisation capability ensures precise compatibility with diverse vehicle cooling system layouts, meeting varied market demands.
