Welding cast iron

The water pump on the Volvo is leaking, went about bought one yesterday to replace it and I got under the truck for a close verifacation that it is the waterpump and not just a gasket leaking.
I found where someone has welded the pump, I'm guessing it cracked and they tried to repair it. The leak is coming out of the weld. I'm toying with the idea of grinding the weld out and rewelding it and taking this $450 new pump back.
Would you mess with it or just put the new one on and be done with it? I've never welded cast, all I have is a mig, no torches or tig.

Fix it right and forget the afro-engineering project and put a new one on it.
+1 the short cut fixes usually end up costing more in the long run
I guess that the weld leaking is a sign that says hell with it, put it in the box and send it back as a core.
but in your case i would replace it
And fiery auto crashes
Some will die in hot pursuit
While sifting through my ashes
Some will fall in love with life
And drink it from a fountain
That is pouring like an avalanche
Coming down the mountain

I was thinking both of these and raise you high temp silicone [:D].
Or jailbreak the chip and tune it to run without water. It's a diesel, should work.
Or, you could fix it the right way and stop messing with you paycheck.
The trick there is to stop the original crack from extending. I was a mechanic for 45 years and I would only do that if there were no new ones available.

Yep.
Do you really like being broke down on the side of the road???
Just take your medicine and use the new pump.
You're never gonna be able to fix it with a MIG welder.
Since we all know how to ream a hole smaller, go that route.

Sage advice indeed.
I'll say it, use a tampon.

It's for his Volvo [;)]
You know you are a redneck when you think a Volvo is a woman's part.
"I didn't have time to do it right but I have time to do it over" comes to mind.

Considering your investment and the possible negative effect on your lively hood or this devolving into a much greater expense and / or loss of time or inability to make a pick up or delivery why take a chance...
Nobody likes to take the hit in the wallet but your 1st best fix is likely to save you money and angst down the road.
But you don't need me to tell you what to do - you know already.

Sometimes doing repairs instead of just changing parts is the best way. Guys who don't work on thier trucks but instead rely on $100 per hour shops go broke. The last truck shop I worked at I say drivers come in and pay $100 per hours for us to chase air leaks then have a $500 bill. Sorry, I'm going to show my arrogance, if you cannot do simple maintenance on a truck you should not be driving one.
As far as just changing parts, the Low Air Beeper didn't work in this truck and that is a DOT Out Of Service, no beeper and you are shut down. Now most drivers would go to a shop and pay for troubleshooting and an $800 instrument cluster, Volvo only seels the complete cluster. I went on Amazon, bought a $2.50 speaker, pulled the cluster out and soldered in the new speaker, saved probably over $1000 doing that.
The water pump, when I was looking for the leak what I found was what appeared to be a weld bead on the body of the pump, due to the location I could only go on what I could see and I knew the pump had to come off. Once I got it off I saw that it was leaking from the weep hole and the weld bead I saw was actually crusty deposits. So the mew pump is on and the old one goes in for core.
And I have epoxied cracks before, one that sticks out in my mind is a Cummins engine in Dodge pickup. He came into the shop with it hosing out coolant, I got under it and found the block had a 6" crack in it. The owner did not want to buy an engine so it was agreed that a non warranty repair would be made, if it worked it worked if not then ohh well, we tried. I drilled both ends of the crack, used a die grinder to make a "V" out of the crack and applied epoxy. To the best of my knowledge 3 years later that pickup is still running.
I believe that when a part can be repaired repair it. When I was one of three FSRs in a shop with over 500 mechanics I saw parts changers and mechanics. Parts changers are expensive as hell, mechanics make things work and save $$. If that water pump had infact been cracked, it would have been repaired even if I had to pay a welder to do it, $450 is too much money to just swap parts.
