If you're looking to keep your Audi Quattro or any of the classic small chassis models running cool, you might want to check out this CSF High-Performance All-Aluminum Radiator. With over 50 years of experience under their belt, CSF knows a thing or two about keeping engines at the right temperature, whether you're cruising down the street or tearing it up at the track. This radiator is designed for performance, and it really shows. It features a robust 2-row, 42mm dual pass core that helps manage heat like a champ, especially if you're pushing the limits with a high horsepower build. The real kicker here is CSF's exclusive B-Tube Technology. Instead of the usual oval tubes, these "B-tubes" are engineered to be stronger and more efficient. They increase the heat transfer surface area by about 15% compared to standard tubes, which means you get better cooling without taking up extra space. It’s like having the efficiency of two smaller tubes crammed into one. The fins are another highlight—measuring 6.5mm tall and designed with a multi-louvered style, they maximize airflow through the radiator core. CSF even tests these in a wind tunnel to ensure they’re performing at their best. Plus, the whole setup is built with 100% all-aluminum, TIG-welded construction, so you know it’s tough enough to handle whatever you throw at it. Installation? Easy-peasy. This radiator is a true drop-in fit, meaning no modifications are needed. You can reuse your OEM hoses or aftermarket ones because the inlet and outlet connections match the factory specs. And if you’re worried about durability, the CNC-machined brackets and the satin black finish give it an OEM+ look that’s built to last. Here’s a quick rundown of the specs:
  • Core Height: 477mm
  • Core Width: 363.5mm
  • Core Thickness: 42mm
  • Inlet Diameter: 32mm (Top Right)
  • Outlet Diameter: 32mm (Bottom Left)
  • Cooling Tubes: CSF's Exclusive B-Tube Technology
  • Multi louvered fins for maximum surface area contact
  • Drop-in fit installation with OEM-style connections
  • 2-Year Limited Warranty
This radiator fits a range of classic Audis, including:
  • Audi 4000 (1980-1984)
  • Audi 80 (1988-1992)
  • Audi 80 Quattro (1988-1992)

CSF takes pride in the quality of its products and offers one of the best warranty’s in the industry. Please refer to the CSF warranty card in the shipping carton for details.

CSF warranty is applicable only to the original owner of the vehicle. Original paper work verifying the proof of purchase and pre-installation cooling system checklist signed by the professional installer is required to process warranty claims.

All warranty claims should be directed to the point of purchase. Due to CSF’s established agreements with Authorized CSF Warehouse Distributors, CSF is unable to handle and/or process warranty related calls/inquires from any individuals – all inquires/warranty related claims should be directed to the point of purchase or an authorized warehouse distributor.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.

Any repairs or alterations to the unit will automatically void the warranty.

Any form of abuse, including the use of improper coolant mixtures, damage caused by steam, corrosion etc and use on commercial vehicles voids the warranty. It is the vehicle owners’ responsibility to maintain the cooling system as specified in the owners manual.
