It's often difficult to diagnose faulty Mountaineer thermostats because they operate normally for a few minutes, and they only cause the vehicle to fully overheat under certain conditions. If your heater stops working, you hear noises like a steam pipe from the engine or your vehicle runs warmer than normal, it's time to order a new thermostat.
