Bronco Thermostats 2022 – Cooling Control That Keeps You Moving

Your 2022 Ford Bronco relies on the thermostat to manage coolant flow and regulate engine temperature. If your thermostat sticks open or closed, it can lead to overheating, poor heater output, or inefficient engine performance—especially under load or off-road conditions.

OEM thermostats are engineered to Ford’s specifications for temperature response, seal integrity, and flow rate. They open and close at the correct temperatures to maintain optimal engine operation, reduce emissions, and protect against overheating. Whether you're off-roading or daily driving, an OEM thermostat ensures consistent and reliable cooling performance.
