• Plastic tank material for OE-style fit and function
• Mechanically jointed cooling fins
• Core dimensions: 9.2100 in. H x 6.1800 in. L x 1.3000 in. W
• Pipe included: No
• Part number: 73962

Application Details

Compatible with Volkswagen Cabrio, Golf, Jetta, Beetle, Passat, and Corrado applications across model years 1985 through 2002, depending on chassis and build details. This heater core is listed for 2000-2002 Volkswagen Cabrio, 1995-1998 Volkswagen Cabrio, 1999 Volkswagen Golf to chassis/VIN 1J-X-250 000, 1999 Volkswagen Jetta with dimensions noted as 234x157x42, 1998 Volkswagen Beetle, 1993-1998 Volkswagen Golf, 1985-1989 Volkswagen Golf, 1992-1998 Volkswagen Jetta, 1990 Volkswagen Jetta, 1985-1986 Volkswagen Jetta, 1990-1997 Volkswagen Passat, 1990-1994 Volkswagen Corrado, 1990-1992 Volkswagen Golf with A/C radiator applications varying by year, make, and model, 1991-1992 Volkswagen Jetta Mexico built vehicle (A/C), and 1991-1992 Volkswagen Jetta Germany built vehicle.

This part cross-references Valeo 812030 for the same application.

What It Helps Address

• Weak or uneven cabin heat
• Coolant leakage inside the HVAC case
• Restricted heater core flow from age or contamination
• Fogging caused by heater core seepage
• Loss of heater performance in Volkswagen Golf, Jetta, Cabrio, Passat, Corrado, or Beetle models

Installation Notes and Tips

Verify the vehicle’s chassis/VIN, build origin, and HVAC configuration before ordering, especially for 1999 Golf and 1991-1992 Jetta applications. Compare the existing core dimensions and port layout to the replacement unit, and inspect the cooling system for contamination before installation. Because pipes are not included, reuse or source the correct vehicle-specific connections as needed.

Quality Assurance

Nissens develops thermal management components to high manufacturing standards and continuously updates its aftermarket coverage as vehicle technology changes. The 73962 heater core reflects that engineering focus with aluminum core construction and OE-style materials for select Volkswagen heating systems.
