DETAILS

Here, you are looking at the CSF Racing Radiator. This is a super-durable all aluminum radiator designed to replace your factory radiator to improve the overall cooling efficiency. Most factory radiators are manufactured using plastic upper and bottom tanks which will eventually weaken over time, and will leak which will cause you to overheat, which will open up an entirely different set of problems. CSF relieves this issue with all-aluminum construction to essentially become the end-all-be-all of radiators.

Features:

  • CAD/CAM designed using Unigraphics Software
  • OE radial and deep drawn aluminum end tanks
  • B-Tube Technology - stronger, most efficient tube in the world
  • Wind tunnel tested for optimal radiator core cooling efficiency
  • "Racing Style" aluminum drain plug
  • Brazed in CAB furnace
  • Military-grade special clad aluminum used for tubes, fins, header
  • Plates and side brackets (JIS 3003 spec minimum)
  • Privately owned factories with full "in-house" tool rooms
  • CNC machined fittings
  • "Master Class" TIG welding
  • Individually leak tested
  • Vibration cycle tested
  • Thermal cycle tested
  • Wind tunnel tested for optimal radiator core cooling efficiency
  • Burst pressure and impulse cycle tested 10,000 times for strength
  • Salt spray tested for corrosion protection
  • 10-foot box "drop test" to ensure packaging protection
  • 30 point fitment inspection on critical dimensions to ensure OE fitment with no modifications necessary
  • Includes radiator cap

More than needed!

The quality of this radiator is tops. Was impossible to get a instruction guide that showed how to install. And the radiator did not include hoses that would be required to take advantage of the oil cooling feature. Plus if was to install that feature, modifications would be required on OEM fans. But I have radiator installed without oil cooling adaption and have been pleased so far.

Radiator is awesome. Oil cooler is a silent killer.

TLDR: If you have this rad/oil cooler combo, check your oil pressures ASAP!

I installed this on my'12 WRX GR a couple of years ago to improve reliability and prevent Boxer explosion.

Shortly after that, I installed an oil pressure gauge on my Killer B oil pan and was shocked to see low pressure after startup and during spirited pulls. And I recorded normal pressure cruising around!

I then went through the entire oiling system, found nothing out of place, and decided to bring the system to stock one piece at a time. Thankfully (or not), I started by disconnecting the CSF oil cooler. And guess what? The oil pressures were back to normal in every scenario I threw at it.

One track day later, I spun a rod bearing in cylinder one at ~56k miles. :(

Coincidence? Maybe not. My gut tells me the fluctuating oil pressure slowly beat up the motor, and sadness ensued. Unfortunately, others have experienced similar oil pressure issues with this radiator/oil cooler (searching the Internets).

Thank you for your review, Nicky.

We are glad to hear that you found the radiator impressive, but we are sorry to learn about your experience with the oil cooler. Your detailed feedback on oil pressure issues is valuable and will help us improve. It is essential to ensure that all components of a high-performance build are fully compatible and tuned to prevent unintended issues, and we understand how frustrating this situation must have been. We appreciate you sharing your experience, and we encourage others to monitor their setups carefully.

Regards,
