mountune Triple Pass Radiator Upgrade, Focus ST

Application: 2013-2018 Focus ST

mountune has teamed up with global cooling experts CSF to offer the ultimate cooling solution for the Focus ST. This new high performance, all-aluminum, triple-pass radiator has been tested and validated over thousands of miles in high powered eco-boost applications, as well as proven on the track in the most demanding conditions. The new mountune Focus ST radiator features CSF’s exclusive B-Tube technology as well as an ultra efficient multi-louvered fin configuration for maximum surface area contact and heat dissipation. Additionally, the Triple-pass flow structure allows the coolant to flow across the core of the radiator 3 times before exiting the radiator for the lowest outlet temperatures possible.

The collaboration between mountune and CSF has resulted in an industry leading radiator that has been designed and engineered to be a complete drop-in fit. All original mounting brackets have been CNC machined for the purpose of allowing the original fan assembly to bolt on without hassle, and the new core to easily drop in place without any modifications required during install.

Once the OEM radiator’s performance is maxed out and coolant temperatures rise, the vehicles protection system activates “limp mode”, reducing engine performance and power. This situation is a typical occurrence during track days and sustained high speed use. The mountune high performance triple-pass radiator upgrade maintains and stabilizes outlet temperatures for constant and consistent performance throughout a wide range of demanding driving conditions. Significantly reducing the risk of power loss while protecting your engine when it’s needed most.

  • Superior performance
  • Easy installation, bolt on performance
  • Triple pass and B-Tube Technology
  • Track tested
  • Engineered to perform on stock and modified cars

4 of 5 almost completely satisfied September 5, 2019
Reviewer: Alec Hargrove from Las Vegas, NV United States  
radiator works great, relatively straight forward install. upper radiator hose not quite the right shape, its almost the exact size its supposed to be, but had to kink end attatched to radiatorin order to fit properly. not a large kink, but a kink nonetheless

5 of 5 Awesome piece November 29, 2018
Reviewer: STigmata from East Coast, FL United States  
Quality. From the plastic covered protection in the box to the welds this product is ultra high quality. A lot better than the factory product. If your looking for maximum performance and want to keep your coolant temps as low w as possible then this is for you. Let’s not forget they tossed in the hoses for free, awesome!

5 of 5 Great product, fast shipping March 23, 2018
Reviewer: Gustavo Montiel from Chula Vista, CA United States  
The radiator works great! I did notice a bump in power because the car runs cooler. Some instructions would be nice for the people like me, that like to work on their own vehicles. But the quality is great, and it fits perfectly like stock!
