The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
When the head gasket begins to fail, the engine may have no symptoms at all. They only begin to occur when the leak has reached an engine oil passage, engine coolant passage or the engine cylinder.
When that happens, the engine may be very difficult to start, and run roughly when idling. There may be oil or coolant leaking, and the engine may begin to overheat, or at least run hot. At this point, there may be coolant in the engine oil pan — this will look creamy and lighter in color than the oil. Also, the radiator or engine coolant reservoir may have a gurgling sound, the presence engine oil, or smell of combustion. And the check engine light will come on.
The coolant being burned in the engine will produce white exhaust that smells sweet, like engine coolant. When the head gasket fails completely, the engine will overheat within minutes of starting, will stall and then won't restart.
A failing heater core may cause the car's interior to smell like engine coolant. The smell will become worse when the heater is turned on. The engine may also begin to run hotter until the vehicle is repaired.
The worst-case scenario is the engine overheating, which can cause extensive engine damage.
If the heater core is clogged, the air that blows when the heater is turned on will not be very hot.
Problems with the intake manifold gasket can create the following symptoms:

A failing radiator can cause the engine to run hot or overheat. Most radiators are made of metal and plastic. The plastic parts can become brittle and crack over time, causing a leak of coolant (typically green or pink in color). All manufacturers have a recommended service interval for coolant renewal. As the coolant ages, the additives breakdown and being to form solid deposits. These deposits will build up in the passages of the cooling system and will eventually clog components, including the radiator. A leaking or clogged radiator must be replaced. Some automatic transmission cars will also have a transmission cooler integrated into the radiator. Lines going to and from the transmission circulate transmission fluid to help cool the transmission in heavy duty applications such as towing or off-roading. If this integrated cooler fails, it can allow transmission fluid and coolant to mix. This will causing shifting issues in addition to overheating.
A coolant leak may be noted from the hoses. Coolant hoses can be damaged by oil leaks, or age. This will lead to swelling or cracking, it is suggested to replace the hoses before they begin leaking to avoid potential overheating.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
The two most common signs of a bad pump are leaks and noises.
Leaking water pumps can result in damage to the drive and timing belts, and cause the engine to overheat. A failed water pump can be caused by other problems in the cooling system, such as a bad thermostat, radiator or head gasket.
When diagnosing a coolant leak in your 2013 Ford Fusion, start with a thorough visual inspection. Look beneath the vehicle for any signs of coolant pooling or dripping, particularly around the radiator, hoses, and water pump, as these are common leak points. Next, check the coolant level in both the reservoir and radiator; a significant drop may indicate a leak that needs attention. Pay close attention to the hoses and connections, inspecting them for any cracks, bulges, or wear, and ensure that all connections are tight. If the initial checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, which can help identify leaks that are not immediately visible. Additionally, be aware of any sweet smell, which is characteristic of coolant and can assist in locating the leak's origin. By following this structured approach, you can effectively diagnose and address coolant leaks, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2013 Ford Fusion, it's essential to understand the common culprits that could be at play. One of the primary sources of leaks is a damaged radiator, which can develop cracks or corrosion over time, leading to coolant escaping. Additionally, worn-out hoses are another frequent issue; these rubber components can deteriorate due to heat and age, resulting in leaks. A faulty water pump is also a potential problem, as it can fail to maintain proper coolant circulation, causing leaks from the engine area. Furthermore, loose or damaged hose clamps may not secure the hoses tightly, allowing coolant to seep out. In more severe cases, a cracked engine block can lead to significant leaks, while a leaking heater core can cause coolant to leak into the cabin of the vehicle. Addressing these issues promptly is crucial to prevent overheating and further engine damage, making regular inspections and maintenance vital for any DIY enthusiast looking to keep their Ford Fusion in top shape.
Addressing a coolant leak in your 2013 Ford Fusion is not just a matter of routine maintenance; it is an urgent issue that requires immediate attention. Coolant plays a vital role in regulating your engine's temperature, and any loss can lead to overheating, which may cause severe damage to engine components. Ignoring a coolant leak can escalate into more significant problems, including reduced fuel efficiency and increased safety risks while driving. The longer you wait to fix the leak, the more likely you are to face costly repairs and potential breakdowns on the road. Therefore, if you notice any signs of a coolant leak, such as puddles under your vehicle or fluctuating temperature gauges, it is crucial to act quickly. Promptly addressing this issue not only ensures the longevity of your vehicle but also maintains its optimal performance and safety.
