Leaking around oil cooler. O-rings or gaskets?

Post by FireFox31 »

My 2000 V70 has a large old fluid stain under the engine seeming to come from the oil cooler. I bought two seal rings for the cooler lines, part 30637339 (9463173). I will install them when the oil is drained during a change. Is this the right solution for this problem? Is something else causing this leak?
