8v92 radiator overflow tank?

[folivier]

Has anyone added an overflow tank to the radiator on our 8v92's?
If you have, what size did you go with, and where did you find one?
I recently added one to my generator radiator, and am wondering why not add one to my engine radiator?

I added a small overflow tank to my 8V92. Found it at Kragen Auto Supply. A larger one would likely be better but mine rarely overflows more than a cup or two of coolant unless I am pulling steep long grades during the summer.
