Your cart is empty.The fiesta ST is a fantastic choice of car for the track or autocross, but it can suffer from some Cooling deficiencies. It’s hard to win a race If you have to hit the pits after only a couple Laps. Constructed of 100% aluminum and featuring a 3-row core, this fiesta ST radiator is the ultimate in Cooling efficiency. This Mishimoto fiesta ST radiator will make sure your fiesta is running cool, Lap after Lap. The radiator core measures in at a massive 52mm thick, requiring our engineers to get creative with the fitment of the fan and shroud. Unlike other Mishimoto radiators, this fiesta ST radiator includes a Mishimoto compact fan shroud for increased airflow through the radiator. This compact fan shroud retains the use of the stock Electric fans, and was stringently tested to ensure that the airflow remained intact for performance applications. Testing during steady-state driving yielded coolant temperature drops of 10°f (5.5°C) When compared to the stock fiesta ST radiator and fan shroud. Like the rest of the Mishimoto lineup of fiesta ST parts, this radiator comes with the Mishimoto lifetime warranty, to ensure superior quality and craftsmanship.

Vehicle: 2016 Ford Fiesta ST. Recently I purchased a Mishimoto radiator for the aforementioned vehicle. Upon installation, my mechanic advised me that both the stock upper and lower hoses were incompatible with said radiator. I was assured by Mishimoto that this unit was a "direct fit" for my vehicle. Unfortunately, it was not. Now we have to search all over Las Vegas for two compatible hoses. Please be more forthcoming with potential customers in the future.

Great fit condenser was closed but it went right in. Lifetime warranty even against accidents. Friends have went with Monotune or Whoosh over this. Big mistake their radiators are smaller. With 180 thermostat Gauge now reads 2 bars less than factory. A must have for the FIST enthusiasts

Excellent packaging, product quality, installation guide, and technical support. My Fiesta ST has a legacy of overheating. The stock radiator is laughably tiny compared to the Mishimoto. Temps are running maybe 5 degrees cooler. I have to push the car hard, but I feel much more comfortable doing so.

Radiator does a great job, but missing bolts for fan shroud.

Nice quality welds, very thick, and awesome cooling capacity. No issues overheating while racing at all. Only reason for not 5 stars is I had to modify one of the mounting holes for the fan motor to get it to fit. Besides that it would’ve been a perfect drop in.
