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 2019 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. Next, check the coolant level in both the reservoir and radiator; a significant drop may indicate a leak. If these initial checks do not reveal the issue, consider performing a pressure test on the cooling system. This involves pressurizing the system and monitoring for any pressure drops, which can pinpoint the location of a leak. Additionally, inspect the radiator and hoses for any signs of wear, such as cracks or bulges, and examine the water pump for leaks, as a malfunctioning pump can contribute to coolant loss. Don’t forget to check the heater core, as leaks here can lead to coolant entering the cabin. Lastly, be alert for any white smoke from the exhaust, which could signal coolant leaking into the combustion chamber. By following this structured diagnostic approach, you can efficiently identify and address coolant leaks in your Mustang.
When dealing with coolant leaks in a 2019 Ford Mustang, it's essential to understand the common culprits that may be at play. One of the primary issues is damaged hoses, which can develop cracks or wear over time, leading to leaks in the coolant system. Additionally, a faulty radiator is another frequent source of leaks; corrosion or physical damage can compromise its integrity. The water pump, responsible for circulating coolant, can also fail and leak due to wear and tear. Another often-overlooked component is the radiator cap; a cracked or malfunctioning cap can allow coolant to escape. Furthermore, loose or damaged clamps that secure the hoses can contribute to leaks, as can a corroded heater core, which may develop leaks over time. If you notice signs such as puddles under your vehicle or a sweet smell inside the cabin, it's crucial to address these issues promptly to avoid overheating and potential engine damage. By being aware of these common causes, DIY enthusiasts can take the necessary steps to diagnose and fix coolant leaks effectively.
Addressing a coolant leak in your 2019 Ford Mustang is not just a matter of routine maintenance; it is an urgent issue that requires immediate attention. Coolant plays a vital role in regulating engine temperature, and a leak can lead to overheating, which may cause irreversible damage to engine components. Ignoring this problem can result in a significant loss of coolant, leading to insufficient cooling and ultimately risking engine failure, which can be both costly and inconvenient. Additionally, a coolant leak can negatively impact your vehicle's fuel efficiency and overall performance, creating safety hazards if your car breaks down unexpectedly. Therefore, it is essential to act swiftly to repair any coolant leaks to maintain the integrity and safety of your Mustang, ensuring it runs smoothly and efficiently for years to come.
