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.
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.
To effectively diagnose a coolant leak in your 2014 Ford Mustang, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the car or around critical components such as the radiator, hoses, and water pump. This initial step can often reveal obvious leaks. Next, consider performing a pressure test on the cooling system, which involves using a hand pump to pressurize the system and identify the exact location of any leaks. Regularly checking the coolant levels is also crucial; a consistent drop in levels can indicate a leak that needs attention. Don’t overlook the radiator cap, as a damaged or worn cap can lead to leaks as well. Additionally, inspect all hoses, clamps, and connections for any signs of wear, cracks, or loose fittings that could compromise the system. Finally, be alert for any white smoke from the exhaust, as this could signal coolant entering the combustion chamber, indicating a more serious issue. By following this diagnostic approach, you can systematically identify and address coolant leaks in your Mustang, ensuring optimal performance and preventing further damage.
When dealing with coolant leaks in a 2014 Ford Mustang, it's essential to understand the common culprits that could be causing the problem. 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 hoses transport coolant throughout the engine and can deteriorate, resulting in leaks. A faulty water pump is also a potential source of coolant loss, as it may fail to maintain proper pressure, causing leaks from the engine. Furthermore, loose or damaged hose clamps can prevent a secure seal, allowing coolant to seep out. In more severe cases, a cracked engine block can lead to significant leaks, necessitating immediate attention from a mechanic. Lastly, a leaking heater core can cause coolant to leak inside the vehicle, often noticeable by a sweet smell or wetness under the dashboard. Addressing these issues promptly is crucial to avoid overheating and further engine damage, making it vital for DIY enthusiasts to inspect these components regularly.
Addressing a coolant leak in a 2014 Ford Mustang is an urgent matter that should not be overlooked. Coolant plays a critical role in maintaining the engine's temperature, and any loss of this vital fluid can lead to overheating, which poses a serious risk to the engine's integrity. If the engine overheats, it can result in catastrophic damage, including warped cylinder heads or a blown head gasket, leading to costly repairs that could have been avoided with timely intervention. Furthermore, a decrease in coolant levels diminishes the engine's cooling efficiency, increasing the likelihood of overheating during operation. Ignoring the symptoms of a coolant leak not only jeopardizes the vehicle's performance but also compromises safety, as an overheated engine can lead to sudden breakdowns or accidents. Therefore, it is crucial for Mustang owners to address any signs of a coolant leak immediately to ensure the vehicle remains safe and reliable while preventing extensive and expensive repairs down the line.
