Am working on a 239 and TRYING to take the water pump off the right side,( as if sitting in the seat) and I can feel the bolt inside the bottom radiator hose and I feel the ridges but when I put a socket on it, it just spins. It does not feel like it is rounded off. Any suggestions as to how to proceed would be apricated.
The one on the right side came loose right off.

 

Not much of a suggestion, ... but you might be able to see the problem (better) with a (mechanics) mirror ?

 

Are you at least using a 6 point socket?

 

Thank you but can it it very well and see all the ridges but for some reason will not break

 

Am using a 6 point socket and have tried an impact wrench without result, but thanks for the info.

 

If it's the last bolt try getting a screw driver in behind the pump , then try loosening the bolt while applying slight pressure to separate the pump from the block .
The threads on the bolt may be toast .

 

Thank you, hadn't thought of that. I will try it.

 

If that doesn't work you'll probably have to get in there with a drill and drill it out. Not the best way but it might be the only way. Start with a small drill bit, us a lot of oil and progress to a larger bit that is slightly smaller the inside diameter of the inner part of the thread.

Even if you can drill it so you can break off the head at least you'll get a better look at the remainder of the bolt after you get the pump off.

 

Or try to apply some heat (hot air fan) and try again after it cooled down.

 

I'd try putting heat on it before getting out the drill.

 

Sounds to me like the threads corroded and fell away from tge main body of the bolt but not enough to allow the bolt to slide out. No amount of heat is going to get that out.

 

There are lots of bolt extractors out there. Everyone has their favorite(s). Heat and Kroil have worked best for me but that bolt is in an awkward spot and too much heat and you will ruin the water pump.

Your impact wrench is probably what got you in trouble in the first place. 12 point sockets are not good to use on old trucks either. This is a job where you need to feel what is happening.

I have not used this one but it seems to look pretty good and has a good rating. Also not too expensive. Lowes nut and bolt extractor

 

But thanks for the info. I found that the head had been rounded a little,( probably from using the impact) and I found out that a 14mm socket is just a shade smaller than a 9/16 , I jammed it on the bolt and it held long enough to get it off.

 

Nicely done.
