Does this radiator come with a drain plug?

Yes, this CSF radiator includes a smooth satin finish, race-style drain plug. This makes draining the cooling system for maintenance or replacement much easier.

Will I need to modify my vehicle to install this radiator?

No, this CSF radiator is designed as a true 'drop-in fit'. It requires no modifications to install and accepts all original equipment components, including hoses and mounting brackets.

What makes CSF's B-Tube Technology different from standard radiator tubes?

CSF's B-Tube Technology uses a specially engineered tube shape that increases the heat transfer surface area by approximately 15% compared to standard oval tubes. This design allows for more efficient cooling by creating a 'dual liquid laminar flow'.

Product Details

CSF has been making radiators for over 50 years, so they know a thing or two about keeping engines cool. If you're working on a 1999-2006 Volkswagen Golf, GTI, Jetta, or GLI, this all-aluminum radiator is a solid choice for improving your cooling system's performance, whether you're building a higher horsepower engine or just want better reliability on the street or track.

What makes this radiator stand out is its 2-row, 42mm core that uses CSF's B-Tube Technology. Instead of a standard oval tube, these B-tubes are shaped to increase the heat transfer surface area by about 15%, giving you more efficient cooling. They also use multi-louvered fins that are precisely aligned to help maximize airflow through the core. The brackets and connections are CNC machined for a precise fit, and it's designed as a direct-fit, meaning it bolts right in using your original mounting hardware and hoses.

This radiator is built to last and perform. It's a well-built unit that CSF trusts for demanding applications, and it's designed to integrate seamlessly with your existing cooling system components.
