Just got done changing the water pump in my '93 Explorer Sport. One of the bolt heads (of the 12) broke off, leaving the rest of the bolt sticking out of the engine block. The one that broke is located in the center of the bottom side. We used a good bit of sealant on both pieces before putting it together with the gasket, of course. Haven't had a chance to check for how much it is leaking, since it's dark out. Was wondering if anyone else has had this problem, and what my chances are that it won't be a major leak. Only reason I think it may not be bad is because there are 12 bolts holding the pump together, instead of the 4-6 for GM vehicles, for example.
Also, any other options if it is a bad leak, other than taking it somewhere and getting the remainder of the bolt drilled out and possibly retapped if necessary? My father in law suggested stop leak, which I am hesitant to use. I don't plan on keeping the vehicle for more than roughly another year. Any input is greatly appreciated.
