Mountune has teamed up with global cooling
experts CSF to offer the ultimate cooling solution for the Focus 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 Focus 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.
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.
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.
