I'll check it, but I did spill antifreeze when I put in the thermostat and again when I put new hoses on it and may not have gotten that area washed off. I will look closely to make sure it's not mole or something alive. It could have stuff in it since it was in storage so long. I did have all the fluids changed, but I'm sure they didn't flush it let along boil it out. Thanks.
