Hey all. I have an 01 Frontier with a V-6. Just recently i've noticed what seems to be a very small radiator leak. It's out of the 2 top corners of the radiaor. There's dried semi-white/transparent spatter spots around those areas. Their small like bb size or less. And only a few spots each side. There's no overheating issue. In fact the truck runs on the cool side as always. The top of the radiator is semi-wet but I tried to pinpoint the leaks with the engine running and I can't find any. Does this sound like a coolant leak? If so, has anyone used any of those stop leak additives that you add to your radiator that worked? I'm thinking of trying one of those additives.
