Beware of Electrolysis…

[tomlamb]

Well my work to my new truck running took a turn for the worse. I have only had this truck for a couple weeks and went to change the coolant only to discover that my lower radiator hose connection was corroded and basically gone. A call to Griffin (it is a 1-55242-X aluminum) tech told me that it looks like electrolysis problem with the coolant. The ground on the electric fan was to the metal shroud through the radiator and core support so when the fan turned on it passed currant through the coolant and basically ate the bottom connection. I never thought something like this could happen, but after a Google search it looks like it is more common then I realized. Just thought I would post this as an FYI to the group and ask if it sounds correct.

If anyone knows about this sort of thing should I bother thying to fix it or get a new radiator?



BTW, They are sending a new lower pipe so I can try to get it welded up and then re-wire the fan. Overall they were a good company to deal with as they said they are sending the new lower pipe at no charge.
