Product Information

CSF High-Performance all-aluminum radiator for the 2000-2002 Audi S4 (B5), covering Base and Avant. It runs a dual-core 2-row 42mm core with CSF's exclusive B-Tube technology, which raises tube heat-transfer surface area by about 15% over standard O-shape tubes for stronger cooling on the street or at the track. Ultra-efficient multi-louvered fins with a 6.5mm fin height maximize airflow through the core. The radiator is a drop-in fit and accepts all factory components, including the quick-connect hoses, AC condenser, mounting brackets, and fan shroud.

Worth considering so far

I usually spend a while checking fitment before ordering parts. The first thing I checked was the overall fit, and everything looked consistent with the listing. The hardest part was getting access to the old component.

Carter Alvarado
Quality seems good overall

I took my time with the installation rather than rushing through it. So far, I am happy with the purchase.

Met my expectations

I had to work around some tight spaces, but that was more about the vehicle than the part. It did what I needed without any drama.

Installed over the weekend

Needed a replacement and decided to try this one. The finish was clean and I did not notice anything bent or loose. The fan shroud and hose alignment were the main things I watched. Would consider this brand again for another repair.

Thomas Murphy
Would recommend checking fitment for this project

This ended up being the part I went with. I inspected the edges and connections before installation and did not see any issues. Nothing to complain about so far.

No issues so far overall

Bought this while sorting out a few things under the hood. The first thing I checked was the packaging around the fins, and everything looked consistent with the listing. I checked for leaks after refilling the cooling system. I would buy it again if I needed the same part.

Jacqueline Meyer
A good match for this project

Got this for a vehicle I have been working on. The part felt solid when I took it out of the box. I checked for leaks after refilling the cooling system. I have only had it installed a short while, but so far so good. I spent more time on removal than fitting the replacement.

Good fit and finish

The original part had seen better days. There was nothing flashy about it; it just looked like a well-made replacement. The fan shroud and hose alignment were the main things I watched. I would buy it again if I needed the same part. I would compare part numbers before ordering.

Better than expected

Good experience overall

I had to work around some tight spaces, but that was more about the vehicle than the part. Not much else to say; it fit and the job is done.

Fitment checked out

Well packaged

Had the car apart already, so I replaced this at the same time. I inspected the edges and connections before installation and did not see any issues. Happy to have the repair finished.

Does the job

Worked for the repair I had planned.

Does the job

I bought this after looking at the dimensions and application notes. The job was not especially fun, but the component itself did not add any headaches. Exactly the sort of uneventful replacement I was hoping for. I did the work myself.

Would recommend checking fitment

Bought this while sorting out a few things under the hood. I checked the connections twice before finishing the job. I made sure the hoses and fan shroud were positioned correctly. Would consider this brand again for another repair.

Would recommend checking fitment

Fair price for a replacement component.

reasonable value so far

This ended up being the part I went with. I would still recommend double-checking the exact vehicle application.

Happy with the fit on my car

Bought this while sorting out a few things under the hood. It took a little time to line everything up, but nothing unusual for this kind of job. So far, I am happy with the purchase. I took photos before removing the old one.

Well packaged

I bought this after looking at the dimensions and application notes. I appreciated that the part looked like the photos rather than something completely different. I checked for leaks after refilling the cooling system. So far, I am happy with the purchase.

Quality seems good

Had the car apart already, so I replaced this at the same time. No surprises when I held it up next to the original component. I checked for leaks after refilling the cooling system. Nothing to complain about so far.
