Detailed Description

One Stop Solutions 98801 is an HVAC heater core engineered as an OE-style replacement for vehicles that need dependable heat transfer and a precise fit behind the dash. It is made from aluminum rather than copper, making it a direct replacement for copper-designed heater cores while maintaining original form and function. This part number 98801 is a practical choice for drivers servicing a Toyota Avalon heater core or a Toyota Camry heater core, as well as Lexus ES300 applications.

Compatible With 1995-1997 Toyota Avalon, N/A; 1992-1996 Lexus ES300, N/A; and 1992-1996 Toyota Camry, N/A. This part cross-references Nissens 94801 for the same application.

What It Helps Solve

• Weak or inconsistent cabin heat
• Coolant leakage from a failing heater core
• Restricted heat transfer caused by internal corrosion or tube failure
• Repeat failures on higher-mileage Toyota Avalon, Camry, and Lexus ES300 vehicles
• Poor fitment from non-OE-style replacement parts

Installation Notes and Tips

Verify the vehicle year, make, and model before installation. Because heater core replacement often requires access behind the instrument panel, compare the original unit to part number 98801 before removal and transfer any required foam or accessories during the repair. Confirm the cooling system is properly drained and refilled after installation.

Quality Assurance

Each heater core is individually pressure tested, and the design is validated through cycle, vibration, burst, and environmental testing. The aluminum construction and plated tubes are used to improve durability and help reduce premature failure in demanding service conditions.
