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 a 2013 Ford Taurus, it's crucial to follow a methodical approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by assessing the coolant level in the reservoir; a significant drop can indicate a leak. Next, inspect the ground beneath the vehicle for any signs of coolant, such as puddles or stains, which can help you trace the leak's origin. After that, carefully examine the radiator and hoses for any visible damage, including cracks or loose connections, as these are frequent sources of leaks. If no obvious issues are detected, consider conducting a pressure test on the cooling system, which can reveal hidden leaks by pressurizing the system and exposing weak points. Additionally, inspect the water pump for any signs of leakage and check the heater core, which may produce a sweet odor if it is leaking. Lastly, be vigilant for symptoms of a failing head gasket, such as white smoke from the exhaust or coolant mixing with engine oil. By adhering to this structured diagnostic process, you can effectively identify and resolve coolant leaks in your Ford Taurus.
When dealing with coolant leaks in a 2013 Ford Taurus, it's essential to understand the common problems that may arise. One frequent culprit is a weeping water pump, which can lead to a gradual loss of coolant, often unnoticed until it becomes a more significant issue. Additionally, a damaged or corroded radiator can create leaks, compromising the vehicle's cooling system. Inspecting the coolant hoses is also crucial, as wear and tear can result in cracks or breaks that allow coolant to escape. Faulty gaskets, particularly the head gasket or intake manifold gasket, can also be a source of leaks, leading to more severe engine problems if not addressed. Lastly, a cracked engine block, while less common, can be a serious issue that requires immediate attention. By being aware of these potential problems, DIYers can take proactive steps to diagnose and repair coolant leaks, ensuring their Ford Taurus remains in optimal condition.
Addressing a coolant leak in a 2013 Ford Taurus is of utmost urgency due to the significant risks associated with neglecting this issue. Coolant plays a vital role in maintaining the engine's temperature, and a leak can quickly lead to overheating, which may result in severe engine damage or even complete failure. For DIY enthusiasts, it’s crucial to recognize that ignoring a coolant leak not only jeopardizes the vehicle's performance but can also lead to costly repairs down the line. Additionally, a coolant leak may indicate underlying problems within the cooling system, such as a damaged hose or radiator, which could escalate if not addressed promptly. Therefore, if you notice any signs of a coolant leak, it is essential to diagnose and repair the issue as soon as possible to ensure the safety and reliability of your vehicle. Taking swift action can prevent further complications and help maintain the overall health of your Ford Taurus.
