My chrome overflow tank, that is about 18" long, and about 2 1/2" around.
Yes, there is two tube inside. One - way down at the very bottow, and the
other is about 4-5 inches, from the top of the tank.
I know in my highlander, the overflow is a plastic 1/2 gal tank, and I usually
keep that alittle less than half way.
But, this tubular overflow, I'm not sure about the elevation the fluid should
be at - - when cold. I tried to get online, on the AFCO radiator website, but
it doesn't say anything about the overflow tank. I just thought, some of you
hot rodders might know what the elevation should be kept at. Thanks
