1997 Grand Caravan 3.3 ltr V6 engine; 105K miles. I was about to get my water pump replaced when my mechanic informed me that one of the 5 bolts has corroded. He said he couldn’t guaranty that it won’t break if he tried to remove it. I thought it is too risky and decided not to proceed with th…

I assume your water pump is leaking? Or are you replacing it for some other reason? Anyway, assuming that the water pump needs to be replaced, then there’s no choice but to remove it. If there’s enough rust there that one of the bolts may break upon removal, so be it. If they all come out, great! I…

It’s a coin flip unfortunately and a sad fact of mechanical life that bolts (especially ones involved with the cooling system) may freeze in place and break off during removal. If the water pump has failed then you have no choice but to proceed with the process and repair the damage as necessary wi…

Been-there-done-that… But if it needs to be done…not much of a choice…And there’s no way you can get any penetrating oil in there either. If it breaks…then it’ll have to be removed…and maybe the hole retapped.

When I run into a situation such as this I prepare for the worst. If the bolt snaps off, I weld a nut to the broken bolt and turn it out. http://www.youtube.com/watch?v=4BFUfGKU_ts&feature=related Tester

I have done this pump on the exact same van. The bolts in question are M6 high strength and are threaded into an aluminum pump housing. I used a significant amount of heat to heat the area around the bolts to break them free. I was able to get all but one out. The one that snapped was at the bot…

Thank you all for your input. I guess I need to take my chances. I’ll get the water pump replaced and hope for the best. The water pump has a small leak and my quick fix has been to add coolant in the reservoir regularly (every 500 miles). I was told that it could get worse anytime (like when I’m o…

That leak means coolant is coming out the weep hole, which means the inner shaft seal is gone. If you keep driving it like this the bearing will blow and you will loose all the coolant VERY fast. The serp. belt will also come off once the bearing goes. I know, becuase that’s what happened to ours…

What I find strange about this story - especially on a vehicle this old - is that there’s almost no such thing as any repair where one could “guarantee” that a bolt won’t break or otherwise be mangled. Its a routine part of auto repair, and mechanics routinely deal with it. I’m wondering a little bit about your mechanic.
