was putting a water pump on, and i tight too much on 2 bolts, and they broke. is it anyway to fix it ?? is it going to cost alot in labor ??
Well if the bolts are sticking out of the engine enough you can try screw extractors you can buy a set at your local store hammer that on then use a wrench or socket Extension to remove it. When you install the new bolts use a little anti-seeze and use a torque wrench.
Remove the water pump. Then you should be able to grab whats left of the bolts with a pair of vise grips and turn them out.
Take the water pump back off. If the broken studs stick out of the block enough you can get a vice-grip pliers on them and remove them. If you can't get a hold on them then you will have to drill a small hole in the stud and use an Easy Out to back out the broken stud(s). Be sure to drill exactly in the center and not too big. Drilling off center or too big and you will destroy the threads in the block. THEN you will have to re-tap the threads and use a larger size stud. Likely you will have to modify the water pump to handle the bigger studs. So be careful. If you are not confident you can handle this then take it to a shop. Ava g'day mate. ) And good luck.
