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.

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 2015 Ford C-Max, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by visually inspecting the engine bay and under the vehicle for any visible signs of coolant, such as puddles or stains, which can indicate the source of the leak. Focus on common leak points, including hose connections, the radiator, and the water pump, as these are frequent culprits in coolant system failures. Next, examine the thermostat housing and the coolant tank, ensuring that both are secure and free from cracks or damage. Don’t overlook the coolant cap, as a faulty seal can also lead to leaks. Additionally, monitor your vehicle's temperature gauge for any fluctuations that could suggest a cooling system issue. By employing these diagnostic techniques, you can identify the source of the leak early, allowing for timely repairs and preventing further damage to your vehicle.
When dealing with coolant leaks in a 2015 Ford C-Max, it's essential to understand the various components of the cooling system that may be at fault. Common culprits include the coolant reservoir, radiator, and the hoses that connect these parts to the engine. Over time, wear and tear can lead to cracks or disconnections, particularly at the junctions where hoses meet the engine or radiator. A radiator leak is another frequent issue, often resulting from corrosion or physical damage. To effectively diagnose a coolant leak, keep an eye out for symptoms such as engine overheating, a noticeable drop in coolant levels, or colorful puddles forming beneath your vehicle. Additionally, if you hear a squealing noise from the belt or see white smoke from the exhaust, these could also indicate a coolant leak. Addressing these problems promptly is crucial to maintaining your vehicle's performance and preventing more severe damage to the engine.
Addressing a coolant leak in your 2015 Ford C-Max is not just a matter of routine maintenance; it is an urgent necessity that can prevent severe damage to your vehicle. When coolant leaks occur, they can lead to engine overheating, which poses a significant risk of catastrophic engine failure. Ignoring these leaks can escalate into costly repairs that could have been avoided with timely intervention. Moreover, a coolant leak can compromise your vehicle's overall performance and fuel efficiency, making it less reliable on the road. Regularly monitoring your coolant levels and promptly addressing any leaks is essential for maintaining the health and longevity of your Ford C-Max. By acting quickly, you not only safeguard your vehicle's performance but also ensure your safety while driving.
