mountune Triple Pass Radiator Upgrade, Fiesta ST

Application: 2013-2018 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

Great radiator October 27, 2018
Reviewer: P.L. from CA United States  
Quality radiator,which looks extremely nice. My fiST runs at normal temperatures considering I didn't change the thermostat, but never goes over 195°. Highly recommend if your car tends to run high coolant temps in the summer.

Outstanding investment October 25, 2018
Reviewer: Dennis Weng from SAN JOSE, CA United States  
I love it.  With my style of driving, this thing has lowered my coolant temp at least 10 to 15 deg.   The shop I took it to for the installation charged me 3 hours of labor.  The guy who did the work told me that it fit like a glove.   This was money well spent.
