I just bought a 93 YJ and the first day I have it, it's leaking coolant, hoping it's the water pump I'm crawling all over it trying to see where the leak is actually coming from, couldn't find it but it seems like the water pump is a good bet. Took it for a drive yesterday and it stopped leaking as bad. I drove it to work this morning and now it's not leaking at all. Good thing or bad thing? It had been sitting for a good while before I bought it.
