Gearbox oil cooler for Volv o Transmission oil cooler 31437022 Engine oil cooler
Product Description:
Auto gearbox oil cooler
OE NO.: 31437022
Applicable vehicle type: For VO LVO
The gearbox oil cooler is a core component that ensures the gearbox oil remains at a constant temperature and extends the lifespan of the gearbox and the oil. It is particularly indispensable for automatic transmissions (AT/CVT/DCT), as it can stabilize the oil temperature within the 70–95°C operating range, thereby preventing oil degradation and component wear caused by overheating.
