Engine oil cooler water hose Automatic Transmission hose outlet for VO LVO Oil cooler hose outlet OE 31319343
Product Description:
Transmission outlet pipe
OE NO.: 31319343
Applicable vehicle type: For VO LVO
The transmission oil line serves as a critical component connecting the gearbox to the oil cooler, responsible for conveying high-temperature transmission fluid to the cooler for dissipation before returning the cooled oil to the gearbox, thereby fulfilling its heat dissipation function. Concurrently, the internal lubrication system of the gearbox utilises these lines to connect various components, ensuring the lubrication and cooling of vital parts such as gears and bearings.
Installation Guidelines:
- Avoid contact with high-temperature components (e.g., exhaust pipes); install heat-insulating sleeves where necessary.
- Recommended fixing point spacing: 300–400mm to prevent vibration-induced wear.
- Pre-lubricate O-rings with grease to avert leakage caused by dry friction.
- Perform vacuum extraction or pressure testing after connection to verify sealing integrity.
Maintenance Interval: Inspect hoses for ageing or leakage every 60,000–80,000 kilometres, synchronised with transmission fluid replacement cycles.
