Engine recovery tank hose for VO LVO Engine coolant overflow hose OE 30776162 Oil cooler transmission hoses
Engine recovery tank hose for VO LVO Engine coolant overflow hose OE 30776162 Transmission oil cooler hoses
Product Description:
Coolant overflow hose
OE NO.: 30776162 31410408
Applicable vehicle type: For VO LVO
The flexible rubber hose connecting the automatic transmission to the oil cooler serves to cool the transmission fluid during circulation. Automatic transmissions generate significant heat during operation, necessitating the oil cooler to maintain fluid temperature within acceptable limits, thereby ensuring proper transmission function and longevity.
Key Performance Characteristics:
- Oil Resistance: This constitutes the most fundamental and critical requirement for transmission oil cooler hoses. The hose material must withstand chemical corrosion from transmission fluid, resisting swelling, hardening, or degradation from prolonged contact with the oil.
- High-Temperature Resistance: Transmission oil cooler hoses must maintain excellent flexibility and sealing performance under elevated temperatures.
- Low-Temperature Resistance: In cold environments, transmission oil cooler hoses must retain flexibility without becoming brittle or rigid due to low temperatures. Superior low-temperature resistance ensures the hose can bend and be installed correctly during winter or in frigid regions, preventing cracking caused by sudden temperature drops.
- Pressure resistance: Transmission oil cooler hoses must withstand the pressure generated by the transmission oil pump.
- Fatigue resistance and service life: As transmission oil cooler hoses endure repeated pressure and vibration during vehicle operation, their materials and construction require excellent fatigue resistance to prolong service life.
- Ageing Resistance and Weathering Resistance: Typically installed within the engine compartment, transmission oil cooler hoses are exposed to environmental factors such as high temperatures, ultraviolet radiation, and ozone. Superior ageing resistance prevents cracking, hardening, and other signs of deterioration during prolonged service.
- Sealing Performance: Transmission oil cooler hoses must maintain excellent sealing integrity to prevent fluid leakage. Connections are typically sealed with O-rings or sealing gaskets, while the hose itself requires uniform wall thickness and adequate elasticity to ensure a tight fit during assembly.
