Reische Performance 170-Degree Thermostat F-150 2011-2025/ Bronco 2021-2025

If it's time to replace that stock thermostat in your 2011-2025 F-150 or 2021-2025 Bronco, then why not take the time to upgrade it for better overall performance? Be sure to purchase this premium Reische Performance 170 Degree Performance Thermostat (FORD-50).

This 170° thermostat is custom-made with the same size diaphragm and bypass control as the OEM unit currently sitting in your vehicle. This provides proper bypass control, which means maximum efficiency from your engine's cooling system. Each of these upgraded thermostats is modified by hand, using only American-crafted parts and then quality inspected to ensure reliable and consistent opening temperatures. Your brand-new Reische Performance Thermostat is a direct-fit upgraded option when it comes time to replace that old, standard-issue thermostat in your late-model Ford!

Your all-new premium-quality Reische Performance Thermostat is intended for F-150s and Broncos running a custom tune--the fan settings in your truck's tune must be set up properly if you want to see the best possible heat dissipation from your cooling system. Otherwise, a low-temperature thermostat will only be effective when your truck is moving because heat cannot be removed unless there is air passing through the radiator. This thermostat will provide the best possible heat dissipation from your setup for both stock and aftermarket radiators, along with a faster warm-up time and better cold weather performance than a standard 160° unit or a thermostat that merely had holes drilled in the diaphragm.

*All Reische Performance thermostats ship with coolant ratio/additive recommendations.
*In extremely cold environments, it may be necessary to add an OEM thermostat to ensure your vehicle's coolant does not run below 165-degrees.
