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 your 2015 Ford Taurus, it's essential to adopt a systematic approach that begins with the most accessible checks before moving on to more complex components. Start by inspecting the area beneath your vehicle for any signs of coolant pooling, which can be identified by its distinct colors—green, orange, or pink. This initial observation can quickly indicate the presence of a leak. Next, examine the hose connections, as loose or damaged hoses are common culprits for coolant leaks. A thorough inspection of the radiator is also crucial; look for any visible cracks or signs of wear that could lead to leakage. Don’t overlook the water pump, as a malfunction here can also result in coolant loss. Pay attention to specific symptoms, such as coolant dripping from the air conditioning compressor or pooling near the alternator, as these can signal more serious issues. Finally, regularly monitor your coolant levels; a consistent drop without visible leaks may suggest an internal leak that requires further investigation. By following this structured diagnostic approach, you can effectively identify and address coolant leaks, ensuring the longevity and performance of your Ford Taurus.
When tackling a coolant leak in a 2015 Ford Taurus, it's crucial to understand the common problems that may arise. The water pump is often a primary suspect, as it can fail and lead to significant coolant loss. Additionally, inspect the radiator hoses and the radiator itself, as wear and tear can cause cracks or leaks. The heater core is another component that may develop leaks, especially if the vehicle has been subjected to extreme temperatures. If you notice your Taurus overheating, it could be a direct result of a coolant leak, so it's essential to check for any signs of coolant draining from the reservoir, even if no visible leaks are apparent. By systematically examining these components, you can effectively diagnose the source of the leak and take the necessary steps to repair it, ensuring your vehicle runs smoothly and efficiently.
Addressing a coolant leak in your 2015 Ford Taurus is not just a matter of convenience; it is a crucial step in maintaining the safety and functionality of your vehicle. Coolant plays a vital role in regulating engine temperature, and a leak can quickly escalate into a serious problem. If left unattended, the engine may overheat, leading to catastrophic damage that could result in costly repairs or even complete engine failure. Moreover, a rapid loss of coolant can leave you stranded on the road, facing an unexpected breakdown. Additionally, a coolant leak may indicate underlying issues within the cooling system, such as a damaged hose or a malfunctioning radiator, which require immediate attention to prevent further complications. Therefore, it is essential to inspect and repair any coolant leaks as soon as they are detected, ensuring the longevity and reliability of your Ford Taurus while safeguarding your safety on the road.
