Detailed Description

One Stop Solutions 98079 is an HVAC heater core designed for the Toyota Tundra heater system. It is a direct replacement for copper-designed heater cores and is made from premium-grade aluminum to match OE form and function. This part cross-references Edelmann 93079 for the same application. If you are replacing a leaking or restricted heater core on a 2000, 2001, or 2002 Toyota Tundra, 98079 provides the correct fitment path without changing the vehicle’s HVAC layout.
