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

Quality piece radiator January 8, 2018
Reviewer: Carlos Ferran  
My OEM Radiator was leak from the plastic end tanks and since the stock rad is bad at cooling the car, a aftermarket radiator solution was in order for me
Currently there are only 2 aftermarket options for our cars,  Mountune and Mishimoto, and after doing some research, Mishimoto is required to pull the front of the car (bumper, front crash bar, radiator support, etc) that was something i was not planning on doing.
So i went with Mountune since you can install it from underneath the car on jackstances and took 1-2 hours to do if you follow the service manual

I dont really track the car, so i cant do a review on before and after with track experience and you cant really see a difference with normal daily driving since temperature is regulated by the thermostat but you can see ( if you have a monitoring device, like a accessport) that the mountune radiator drops temps faster than the oem one and keeps the car cooler when i was doing some spirited driving on the twisty roads by 10f
