If you’re looking to keep your engine running cool, you really can’t go wrong with a CSF radiator. These guys know their stuff. With over 3,200 applications, they’ve got just about every ride covered, from Acura to Volkswagen. So whether you’ve got a classic or a modern machine, CSF has the right fit for you.

Now, let’s talk about what makes these radiators stand out. They’re built to last, using materials that are in line with what you’d expect from the factory—whether that’s Copper-Brass or all-aluminum. The CSF radiators are crafted with high-performance standards in mind, and they’ve been doing this for over 50 years. That’s a lot of experience, and it shows in their quality.

The engineering behind these radiators is impressive. They’ve been wind tunnel tested to ensure they deliver the cooling performance you need, especially when you’re pushing your vehicle to the limits. The construction features OEM-specified plastic tanks paired with an aluminum core, which is designed to handle the heat. Speaking of heat, the gaskets are made from special EPDM rubber that can withstand extreme temperatures, down to -120°F. So, you know they’re tough.

Here’s a quick rundown of the specs:

  • Radiator Type: Downflow
  • Rows: 1
  • Core Length: 19 5/8"
  • Core Width: 29 11/16"
  • Core Thickness: 1 1/4"

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.
