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 2007 Ford Mustang, start by checking for any visible signs of coolant pooling under the vehicle, as this can quickly indicate the source of the leak. Next, inspect the hoses connected to the radiator for any visible damage such as cracks or loose fittings, which are common culprits. Pay close attention to the radiator itself, looking for signs of corrosion or leaks that may not be immediately obvious. If these initial checks do not reveal the issue, consider performing a pressure test on the cooling system, as this can help pinpoint leaks that are not visible to the naked eye. Additionally, examine the water pump for any signs of leakage or wear, as a faulty pump can lead to significant coolant loss. Don’t forget to check the heater core, especially if you detect a sweet smell inside the cabin, which can indicate a leak. Ensure that the radiator cap is functioning properly, as a faulty cap can also lead to coolant loss. Finally, keep an eye on your coolant levels over time; a consistent drop can signal a leak that needs addressing. By following this structured approach, you can efficiently diagnose and address coolant leaks in your Mustang, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2007 Ford Mustang, it's crucial to understand the common problems that may arise. One of the primary culprits is a damaged radiator, which can develop cracks or corrosion over time, leading to leaks. Additionally, worn-out hoses are often a significant factor; as they age, they can become brittle and develop holes or tears, allowing coolant to escape. Another potential issue is a faulty water pump, which can leak coolant if its seals are compromised. It's also important to check the hose clamps, as loose or damaged clamps may fail to secure the hoses properly, resulting in leaks. In more severe cases, a cracked engine block can lead to significant coolant loss and should be inspected by a professional. Lastly, a leaking heater core can cause coolant to leak inside the vehicle, often noticeable by a sweet smell or wet carpets. Addressing these issues promptly is essential to prevent overheating and protect your engine, making regular inspections and maintenance vital for the longevity of your Mustang.
Addressing a coolant leak in a 2007 Ford Mustang is an urgent matter that should not be overlooked. Coolant plays a critical role in regulating engine temperature; without it, the engine is at risk of overheating, which can lead to catastrophic damage to vital components. Ignoring a coolant leak can result in a gradual loss of coolant, ultimately leading to insufficient cooling and potential engine failure, which can incur costly repairs. Moreover, a coolant leak can adversely affect the vehicle's overall performance, causing it to operate inefficiently and potentially leading to dangerous driving conditions. Therefore, it is essential to act quickly when a coolant leak is detected to ensure the safety of the vehicle and its occupants, as well as to maintain the Mustang's performance and longevity.
