| FORD-G5 Product Details (DISCONTINUED) |
TEMP:170° DIAM:54mm TYPE:Hot-side, Bypass
|
|
Our FORD-G5 product was discontinued in 2020 so we now recommend the Motorad 354-180 180° thermostat for this application, as it is the only known low temp alternative that fits the GT500 bypass properly.
|
 |
|
The FORD-G5 thermostat is modified by hand specifically for your GT500. It also has the same size diaphragm and proper bypass control so you are guaranteed maximum efficiency from your cooling system. 2007-14 GT500 owners will notice a substantial drop in coolant temps over their stock 192° unit with the FORD-G5 installed. 100% made in USA.

| A retune is generally not required with use of our thermostats, however to get the best possible heat dissipation and most consistent temps, your fan settings should be lowered in your tune. Otherwise a low temp thermostat will only be effective when the vehicle is moving because heat cannot be removed unless there is air passing through the radiator. Unfortunately there are few programmers available at this time capable of modifying fan settings in most of the new Ford engine management systems. The fan speed tables will need to be adjusted through a custom tune (available from most of our vendors) or via tuning software. These new systems estimate coolant temps based on readings from a dry head temp sensor. However these ‘inferred’ ECT values can be more volatile and may read as much as 8-10° hotter than actual coolant temps. This means that a vehicle using our 170° thermostat could see ECT anywhere between 165-205°, depending upon conditions and fan settings. We rely on your feedback, so please let us know if you become aware of any new developments in managing the fan settings for these applications. |
