What you need to know
2005-2010 GT focus, with checked seller pages covering broader 2005-2014 applications. Diagnose fan command, relay/fuse, connector heat damage, coolant condition, thermostat, cap, pump, airflow obstruction, shrouding/ducting and combustion-gas risk before buying a radiator. MMRAD-MUS-05 is manual-transmission fitment. A larger radiator alone does not fix missing airflow or tune-related fan command.
OEM numbers
Checked replacement fan path: AmericanMuscle item 458592 for 2005-2014 Mustang GT/V6. Performance radiator: Mishimoto MMRAD-MUS-05 for 2005-2014 manual-transmission Mustang. Ford DR3Z-8C607-DMotorcraft RF-394 and radiator H2MZ-8005-T remain catalog references requiring VIN/option confirmationno complete supersession chain is claimed.Supersession
No complete Ford supersession chain is printed. Replacement fan, Ford service fan and manual-transmission aluminum radiator are separate paths selected by VIN, engine, transmission and cooling package.
Fitment
2005-2010 GT focus, with checked seller pages covering broader 2005-2014 applications. Diagnose fan command, relay/fuse, connector heat damage, coolant condition, thermostat, cap, pump, airflow obstruction, shrouding/ducting and combustion-gas risk before buying a radiator. MMRAD-MUS-05 is manual-transmission fitment. A larger radiator alone does not fix missing airflow or tune-related fan command.
Aftermarket options
Checked direct-replacement fan assembly and Mishimoto manual-transmission aluminum radiator. Drift/desert setup advice remains deliberately limited to diagnosis and verified airflow basics until Michael rules scope; no percentage cooling-gain promise is adopted.
Before you buy
Diagnose the system before buying parts: fan command, fuse/relay, connector heat, coolant, thermostat, cap, pump, airflow, ducting and combustion-gas risk all matter. The checked aluminum radiator is manual-transmission fitment. No radiator-only fix or motorsport performance gain is promised.
