Mazda CX-5 Service & Repair Manual: Thermostat Removal/Installation

Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding engine coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.

When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.
