mountune Triple Pass Radiator Upgrade, Fiesta ST

Application: 2013-2019 Fiesta ST

Mountune has teamed up with global cooling experts CSF to offer the ultimate cooling solution for the Fiesta 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 Fiesta 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
  • Compatible with original fan, no need for clumsy unreliable aftermarket fans
  • Track and big turbo proven

5 of 5 A must have July 3, 2020
Reviewer: James Lynch from Poway, CA United States  
Hands down the best mod you can do for your Fiesta ST. It just works. Temps before the upgrade would get high in warm weather. Now I rarely see anything over 200 degrees. Run the AC all you want, idle as long as you want, beat on it all you want. You'll be fine. Just buy it

5 of 5 Excellent upgrade decision June 29, 2020
Reviewer: William Schmidt from Prescott, AZ United States  
The extra capacity of this radiator upgrade is necessary in Arizona where temperatures can reach 115 degrees, especially when climbing from the lower altitudes around Phoenix to the 5500 ft of Prescott. It was fortunate for me that a bolt-on upgrade was so readily available, so promptly shipped, and expertly installed by mechanics who had previously worked on Mountune equipment in California. Thanks to all of you for making this so simple.

5 of 5 Well worth the money June 7, 2020
Reviewer: Daniel from Germany  
Install was pretty straight forward and the coolant temps I'm getting are incredible. Been on for about a week and my temps haven't gone over 197, amazing considering what my temps were. Also the radiator on the Mountune UK site will fit a U.S. spec fiesta just so you are aware. I'm overseas and the shipping from the Mountune USA site was over $200 so I'm glad I found another option. Shipping from the UK was only 17 pounds.

5 of 5 Mountune Radiator May 5, 2020
Reviewer: Alex S. from Inglewood, CA United States  
Absolutely satisfied with my radiator. Been running it for a few days now in this beautiful CA weather (86 degrees out) and I’m surprised with the temps I’m getting even doing some spirited driving. Best investment I’ve made!
