1963-1964 ALUMINUM EXPANSION TANK – PRESSED TUBES CORRECT DATE (ND)

Description

The radiator surge tanks produced from 1961 through 1964 used tubes that were pressed in and lightly welded from the inside only. These fittings are very fragile and will break off with only a small amount of side fore when installing or removing a hose. To address this problem, GM improved the tanks in 1965 and later by adding a fillet weld around the tube on the outside. Special care must be taken when working with these parts. Any fittings that are broken off during installation or service are not considered a defect or covered under warranty.
