Saw some posts from a few years ago concerning broken water pump stud bolts. I am going through this currently with my 98 EB 5.0. Current mileage is 233,486 and I snapped off two of the studs removing the water pump. Now...here's what i did to remove those broken studs. A friend brought his torch over and I borrowed some snap-on bolt extractors from a mechanic friend. I also used some good penetrating oil. The studs were broken off even with the water pump housing so once the pump was off, there was about 3/4 " exposed. I douched it with penetrating oil, heated it up, banged on it with a ball pean, repeat.... For about an hour. It's almost guaranteed that the threads going into the block are not corroded. It's where the stud goes through the timing chain case where it's stuck. Repetitive heating & beating & oiling will free it from that aluminum case. It took me around an hour for each stud. Be patient and don't be premature or you'll break it off again.
Now.... The issue I'm having now is finding replacement studs that fit. I purchased two identical stud kits from two different parts stores and neither of them have what I need. I'm headed to the hardware stores in the morning to find some grade 8 bolts so I can finish the job.
