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.
