61-62 Expansion Tank (Dated 61A)
Item #:
In Stock - Ships Monday

New reproduction 1961-1962 Corvette Harrison expansion tanks are correctly dated for your Corvette restoration. Includes original style pressed-in tubes. Dated 61A.

All original dates are available. See Zip # M-2414. Corvette expansion tanks are date coded based on a production of 1-2 months prior to the assembly date of your Corvette. Made in USA.

Note: Original 1961-1964 Corvettes expansion tanks came with pressed-in tubes. The tubes became an issue as wrestling with heater hose connections would often break loose the connection and cause the tank to leak. GM fixed this problem with their later design and service tanks. All tanks are pressure tested prior to shipping - it's the responsibility of the customer for correct hose installation to ensure the pressed-in tubes do not become damaged. Zip recommends using a light grease to help slide the hose into position when installing on the tube. To eliminate leakage problems and provide a worry-free installation, Zip's replacement Corvette expansion tanks feature welded tubes.
