Re: aluminum coolant pipes

["David Teitelbaum" <jtrealty@xxxx>]

The entire area around the pinhole is going to be too thin to weld due 
to the corrosion. The choices are to weld a patch over the area of the 
leak or replacement of the pipe. Another possability is if you go to 
the auto parts store maybe they can find you a hose that has a bend in 
it like the one you have but is a little longer so you can go over the 
spot. Since you have found 1 spot you should remove ALL hoses and 
clean the corrosion from all pipes. This happens because the coolant 
gets old and turns acidic and attacks the aluminum. It also indicates 
the hoses are old and need to be replaced. Ther is no easy fix because 
of the pressure that must be contained.
