Hi. The engine oil cooler uses engine coolant to cool the oil during operation. If you need further assistance, I recommend you have a certified technician, like one from YourMechanic, inspect the oil leak on your vehicle and suggest an appropriate repair. A leak at this seal can cause catastrophic engine damage.
