The number one thing you need to do if you are experiencing engine coolant overtemperature is to stop your vehicle where it’s convenient and get a mechanic to check the engine temperature coolant sensor and replace the current one with a new one. What to Do if Your Ford Fusion is Displaying Engine coolant overtemperature? 1. If your radiator leaks, it will allow coolant to escape into the vehicle and potentially cause damage.Ī leaking radiator can also cause overheating issues that may result in a blown head gasket or other serious problems with your Ford. Leaking RadiatorĪ radiator is one of the most vital components of your Ford cooling system and is responsible for cooling the engine’s coolant. This can also lead to major problems with your vehicle’s performance as well as damage to other parts of your engine. When this happens, it allows coolant to leak into the combustion chamber of one or more cylinders and causes them to overheat. Blown HeadgasketĪ blown head gasket is a problem that occurs when the gasket between your engine’s cylinder head and the block becomes damaged or completely fails.
Low coolant can also cause other issues such as engine overheating. This can cause the engine to overheat and trigger an “Engine Coolant Overtemperature” warning on your dashboard. If your car has low coolant, it will not be able to maintain the proper temperature. If your thermostat fails it can cause the coolant temperature to increase, causing the car to overheat. It does this by restricting the flow of coolant from the radiator to the engine at a certain temperature level. Bad thermostatĪ thermostat is responsible for regulating the temperature of your engine. That said, there are other possible causes that can cause the issue. Now, we know that 98% of the coolant temperature sensor is the most common cause of engine coolant over temperature on a Ford Fusion. Other Possible Causes for “Engine Coolant Overtemperature” The coolant temp sensor is known to fail in most ford vehicles, usually caused by water/coolant leaking into the sensor itself. If this sensor fails or becomes loose, it will throw up the code, usually followed by a p1229 (cylinder head overtemperature). The Coolant temperature sensor is responsible for monitoring the temperature of your engine coolant. The most common cause for this issue is a bad coolant temperature sensor, as Auto tech, I would say this is the most common cause of engine coolant over temperature on a Ford Fusion. What Causes Ford’s” Engine Coolant Overtemperature”? Bad Coolant Temperature Sensor This is a very common problem on ford fusions and can happen for a number of reasons, which I will discuss below.
#2015 EXPLORER ENGINE COOLANT OVER TEMPERATURE CODE#
The error fault code simply means that your Ford has detected that the temperature of your engine coolant is too high.
Other Possible Causes for “Engine Coolant Overtemperature”.What Causes Ford’s” Engine Coolant Overtemperature”?.What Does Engine Coolant Over Temperature Mean on a Ford Fusion?.Remove and discard the intake manifold and thermostat housing gaskets. Remove the 10 bolts and the lower intake manifold. Remove the 2 thermostat housing-to-lower intake manifold bolts. Remove the bolt from the fuel supply tube-to-rail bracket. REFER to Section 310-00, Quick Connect Coupling. Refer to Upper Intake Manifold.ĭisconnect the 6 fuel injector electrical connectors.ĭisconnect the fuel supply tube-to-fuel rail quick connect coupling. REFER to Section 303-03, Cooling System Draining, Filling and Bleeding. REFER to Section 414-01, Battery Disconnect.ĭrain the cooling system. REFER to Section 310-00, Fuel System Pressure Release.ĭisconnect the battery ground cable. REFER to Section 100-02, Jacking and Lifting, Lifting Points. With the vehicle in NEUTRAL, position it on a hoist. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure. NOTICE: During engine repair procedures, cleanliness is extremely important.
Why are you replacing the sensor? What is the issue? The manifold must be removed to access the sensor. The sensor is under the lower intake manifold.
