Ok, I feel a little dumb asking this, I know nothing about motors, but I'm learning! My Wrangler is leaking antifreeze, it looked like it was coming from the lower radiator hose, so I replaced that. Its still leaking and I'm wondering what the upper part of the lower hose is attached to? I'm going to guess water pump? Its hard to tell for sure because there is a pully and belt in the way. The only reason I want to verify is because it leaks when the Jeeps not running (ie overnight) and some nights not at all, which I'm told usually doesn't fit a water pump going out, its usually all or nothing. The leak is running down the lower hose from the top. Thoughts? Thanks in advance!
