The thermostat maintains the engine temperature by circulating coolant through the engine block. When a thermostat stick open or is blocked, the right amount of coolant doesn't reach the engine. Signs of a problem with the Mazda MX-5 thermostat include bubbling or boiling noises or problems with your heater in the winter. Find MX-5 thermostats at AutoZone and order online for Same Day Store Pickup (in most cases) or Free Shipping on purchases of $75 or more.
