Need a 1963 Avanti heater core? Our customer needed a Avanti radiator and asked about heater cores. We built him a radiator of copper and brass to keep his engine cool and built him a copper and brass heater core to keep him warm.

*The electrical devices in the car create stray electric DC current that runs through your cooling system. Electrolysis occurs when electrical current routs itself through the vehicle coolant in search for an electric ground. Evidence of electrolysis includes unexplained or reoccurring pinhole leaks in a heater core or radiator. Pinholes can form anywhere along the tubes, tank walls or thin spots in the material.
Aluminum radiators and heater cores leak not only from electrolysis but also degradation of the corrosive inhibiters in the coolant or improper ratios of coolant to distilled water. This may be the result of chlorides, sulfate and general hardness contained in common tap water.
A one gallon jug of coolant contains about 250 ppm silicates. In theory, in a 50/50 mix the vehicle’s overall silicate level should start out at 125 ppm minimum. The silicate will begin a plating action on the radiator’s aluminum surfaces. Unfortunately surface conditions of the aluminum will dictate the degree of plating that actually occurs. As a consequently something less than 125 ppm silicate level could end up in the final solution in a fairly short period. For this reason most mechanics and recommend a flush & fill at 24 Months/30,000 miles. Failure to do so results in a premature failure of the aluminum radiator and expense of removal and replacement; a costly expense.
