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.

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 2016 Ford Mustang, begin with a comprehensive visual inspection both under the hood and in the area where you typically park. Look for any visible signs of coolant, such as puddles or stains, which can provide immediate clues. Next, monitor the coolant level in the reservoir; a consistent decrease may indicate a leak that needs attention. If these preliminary checks do not yield results, consider conducting a pressure test on the cooling system, as this can help pinpoint the exact location of the leak. It's also crucial to inspect the hoses and connections for any signs of wear, cracks, or loose fittings that could be contributing to the issue. Additionally, examine the radiator and water pump for any signs of leakage or corrosion, as these components are often culprits in coolant leaks. Be vigilant for any steam or a sweet smell while driving, as these symptoms can further indicate a coolant leak. If you still cannot identify the source after these steps, consulting a mechanic for a professional diagnosis may be necessary. By following this structured diagnostic approach, you can systematically identify and address the coolant leak in your Mustang, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2016 Ford Mustang, it's essential to understand the common problems that may arise. One frequent culprit is corrosion and grime buildup in the radiator, often a result of inadequate maintenance. This can lead to leaks that compromise the cooling system's efficiency. Additionally, pressure issues stemming from a faulty radiator cap or a weakened cooling system can also cause coolant to escape. It's important to check for loose hose connections, as these can easily lead to leaks if not properly secured. A broken radiator or a failing water pump are more severe issues that can result in significant coolant loss, requiring immediate attention. Lastly, a failing head gasket can be a hidden cause of coolant leaks, sometimes presenting no obvious symptoms, making it crucial for DIYers to be vigilant in their inspections. By understanding these common causes, Mustang owners can effectively diagnose and address coolant leaks, ensuring their vehicle remains in optimal condition.
Addressing a coolant leak in your 2016 Ford Mustang is not just a matter of convenience; it is a critical maintenance task that demands immediate attention. Ignoring the signs of a coolant leak, such as overheating or colorful puddles under your vehicle, can lead to severe engine damage and costly repairs. The urgency of fixing a coolant leak stems from the risk of overheating, which can warp engine components and compromise the vehicle's overall performance. For DIY enthusiasts, it is essential to regularly check the coolant levels and inspect the reservoir, radiator, and hoses for any signs of wear or damage. By taking prompt action to identify and repair a coolant leak, you not only safeguard your Mustang's engine but also ensure a smoother and safer driving experience. Remember, the sooner you address these symptoms, the less likely you are to face significant mechanical failures down the road.
