Tread size needed

[thezoz2001]

OK, hears the scoop,
The water pump went out in my van. It is
1994 Voyager 3.0 V6
I was able the replace the water pump (a lot of work), but when I was installing the new water pump I striped the threads on one the bolt holes on the engine block. There are to bolt sizes on the water pump. One needs a 12mm socket and one needs a 10mm socket. I need specs on the one with the 10mm bolt head so that I can get an incert for the bolt hole. If anyone can tell me where it is or knows where I can find it I would be a very happy camper.

If you have the bolt handy that you stripped the hole out with, take it or a similar size bolt to most any parts store and they can fix you up with a heli-coil kit that can help you fix the hole.

I just got through fixing a similar problem with my 3.3 where a previous owner had broke a bolt off on the bottom hole of the water pump to housing (a guaranteed leak)

I had to get one of those 90 degree drill adaptors so I could get to the hole to drill it out.

Have fun!

Thanks for the info. Do you have any place that you can reamend?

I dont know what part stores are in your area, but here in Oklahoma I would suggest Autozone, Napa or O'Reilly as places to get the heli coils.
Of course a machine shop supply store would be able to give you more information on how to do the process if you have never done it before.

I am sure you know to go slow with the tap and back it out often when threading the hole for the heli coil and use lots of lubrication while doing it
