Warmth and Silence: Avanti Heater Core and Blower Motor Replacement Guide
Is your Avanti heater core leaking or your blower motor squealing? Don't let a complex-looking dashboard discourage you from a comfortable ride. In this detailed guide, Dan Booth breaks down the professional method for removing and reinstalling the heater assembly for all 1963–1985 models.
Learn the "specialist’s shortcuts," including how to swap the core without draining your radiator and a clever "paint stick" trick for routing wires through the firewall. This article covers essential technical details, such as drilling the NOS mounting flange for cable clearance and properly balancing the original squirrel cage. Whether you need a simple gasket refresh or a complete blower motor rebuild, this guide provides the factory-spec roadmap to a quiet, efficient heating system.

Up for auction is a New Old Stock Heat core for the 1987-1988 Avanti ( Conv. Coupe & LSC) It may fit 1989-1991 Avantis but you would have to send me your old 1989-1991 Heater core so I can compare them. It will NOT fit 1963-1964 Studebaker Avantis or 1965-1985 Avantis. These were custom made for Avanti Motors and are very rare. Because most of the new car dealers for the 1987 and up Avantis didn’t stock hardly any new replacement parts on their shelves. If you need a new heater core for the 1963-1985 Avanti just email me and I will put one on Ebay for you. I also can not give you any advice on how to change the 1987—up heater core, as I never have changed one. I am sorry but the winning bidder is on his/her own for that information.
