RE: [DML] Powder coating back of water pump?

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Stephen, I have seen a lot of water pump backs. But I have never seen one
that has leaked from the tube inserted into the back.  I have seen the tubes
very corroded and needed replaced, but not from expansion. If it was going
to leak it would began to corrode from inside out because of the coolant.
I don't think going to the trouble will help in the corrosion of the tube,
but it would look better, but who would see it.

Subject: [DML] Powder coating back of water pump?





While kicking around the Valley of Death, water pump replacement was
at the top of the list. I would like to powder coat the back since I
found it full of corrosion, figured it was an ideal canidate.
My concern is the steel pipe nipple mounted in the cast aluminum.
Knowing that the metals expand and contract at different rates. Has
anyone ever powder coated one sucessfully?
Thanks,
Stephen
