Expension Tank

[Hugh H.]

If my car was built late May 1963 what would the date code be on my expension tank? Thanks

It's always nice to try to match it to the radiator date code. But if that doesn't work 63 D would be fine.

Original radiator long gone, but would like to change the expension tank with a correct date code, thanks,

Re: Expension Tank

My original radiator let go in 1975, and my expansion tank went with it (Prestone to Zerex chemical reaction). I replaced both with 1975 dated new parts with no concern for dating back then. The radiator is still going strong, but I did replace my expansion tank back in the 90's with a new 63 dated one month before my production date of July, or 63F. That was the "rule of thumb" back then.

Hi Hugh,

My mid-May coupe had it's original expansion tank until I replaced it along with the rad about 3 or 4 years ago.
The date code was 63 E.
