Spectra 98233 HVAC Heater Core

The Spectra 98233 HVAC heater core is a direct-fit replacement for select Audi and Volkswagen applications. It is built to restore cabin heat performance when the original heater core is leaking, restricted, or no longer transferring heat efficiently.

Key Features

  • HVAC heater core for passenger compartment heat exchange
  • OE-style replacement for select Audi A4, A4 Quattro, S4, RS4, and Volkswagen Passat applications
  • Engineered and manufactured with quality control checks to match original equipment performance targets
  • Cross-references Spectra Premium 98233 for the same application
  • Also cross-references APDI 9010444 for select fitments

Detailed Description

Use the Spectra 98233 heater core when servicing heating system failures on 1988-2005 Audi and Volkswagen vehicles. This HVAC heater core is intended for applications including 1996-2001 Audi A4, 1996-2001 Audi A4 Quattro, 2000-2002 Audi S4, 2002 Audi RS4, and 1998-2005 Volkswagen Passat, along with additional Audi 80, 90, Cabriolet, and Coupe Quattro fitments. The part number 98233 is a practical reference when matching the correct heater core for these vehicles.

What It Helps Fix

  • Weak or uneven cabin heat
  • Coolant odor inside the vehicle
  • Coolant loss from a leaking heater core
  • Restricted coolant flow through the HVAC heater circuit
  • Fogging or dampness caused by heater core seepage

Installation Notes and Tips

Verify year, make, and model before ordering, since this heater core is used across multiple Audi and Volkswagen platforms. Confirm the existing core matches the vehicle’s HVAC layout and compare the original part number to 98233 during diagnosis. Because heater core replacement often requires access through the dash or HVAC case, inspect related hoses, seals, and coolant condition during service.

Quality Assurance

Spectra Premium states that its engineering, manufacturing methods, and quality control are used to help these HVAC heater cores meet or exceed original equipment performance expectations.
