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

Reviewer: Matthew Smith from Lewisville, TX United States  
Radiator was beautiful, install was a breeze, and shipping was fast. I have been nothing but happy with Mountune and will continue to purchase through them.

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

This Rad should come stock August 15, 2017
Reviewer: Mario d from Calgary, AB Canada  
The radiator is 1000% worth it. I never had any troubles back home in Calgary with temps. But as soon as I started my road trip to California and we hit the California border the cars temp was out of control. This was at temps over 34c / 93f With A/C on going 70-75mph coolant temp was at 115c. A/C off at the same speeds it was 105. At times we had to have them heat on max to drive and it would still be at 102/103c

After the install we had an hour drive through downtown LA rush hour traffic in 92f weather and the coolant temp never went above 90.5c

Driving back to Canada temps never went above 190f, I've yet to take the car on the track but I am sure this will make a huge difference.

Coolant is a mix of ford coolant and distilled water as I had to replace it again after my MRX turbo install. Your coolant mixture based on your climate may return different results
