Detailed Description

This OSC radiator, Part Number 2034, is engineered for OE-style fit and cooling performance in the Audi A4, Audi A4 Quattro, Audi S4, and Volkswagen Passat. The radiator uses premium-grade materials, cadmium-plated tubes, and factory-style component placement to support proper fitment and thermal control. It is built as a crossflow unit with a plated transmission cooler and no engine oil cooler provision, matching the original cooling layout where equipped.

OSC designs this radiator with added durability features such as a thicker core and increased fin density to address heat load in higher-mileage vehicles. The unit is pressure tested during production and assembled with fitted components torqued to factory specifications. Part Number 2034 is a direct replacement choice for drivers searching for a radiator for 1997-2001 Audi A4 Quattro, 2000-2002 Audi S4, or 1998-2005 Volkswagen Passat cooling system service.

This part cross-references APDI 8012034 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or weakened radiator flow
• Transmission fluid temperature issues related to a failing cooler circuit
• Cooling system loss from worn seals or gasket failure
• Reduced heat rejection in high-mileage Audi and Volkswagen vehicles

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler line spacing before installation. This radiator is a crossflow design and should be matched to the vehicle’s original cooling configuration. Confirm fitment for 1996 Audi A4 and A4 Quattro models built from VIN T210001 and later. Inspect hoses, clamps, and cooler lines for wear before transferring the new radiator into service.

Quality Assurance

OSC radiators are produced with OE-style engineering and are individually pressure tested during manufacturing. The radiator core and cooler circuits are tested before and after assembly to help confirm sealing and function. Part Number 2034 is built to support original-equipment cooling requirements on the listed Audi and Volkswagen applications.
