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 2010 INFINITI FX50, begin by visually inspecting the area beneath your vehicle for any puddles of coolant, which typically appear in bright green, orange, or pink hues. This initial check can quickly indicate if there is an external leak. Next, examine the radiator for any signs of damage, such as wet spots or corrosion, which may suggest a leak. If no obvious issues are found, consider performing a pressure test on the cooling system; this method can help identify leaks that are not immediately visible. Following this, inspect all hoses and connections for any cracks or loose fittings, tightening any that are not secure and replacing any damaged components. Don’t overlook the water pump, as a malfunction here can also lead to coolant leaks. Additionally, check the heater core, as leaks in this area can result in coolant entering the cabin. Finally, keep a close watch on your coolant levels; a significant drop without visible leaks may indicate an internal issue that requires further investigation. By following this structured approach, you can efficiently diagnose and address coolant leaks, ensuring the longevity and performance of your vehicle.
When dealing with coolant leaks in a 2010 INFINITI FX50, it's essential to understand the common culprits that may be at play. One of the primary sources of leaks is a damaged radiator, which can develop cracks or corrosion over time, leading to coolant escaping. Additionally, worn-out hoses are another frequent issue; these rubber components can deteriorate due to heat and age, resulting in leaks. A faulty water pump is also a potential problem, as it may leak coolant from the pump itself or its gasket, compromising the cooling system's integrity. In more severe cases, a cracked engine block can lead to significant coolant loss, which requires immediate attention. Furthermore, a loose or damaged radiator cap can allow coolant to escape from the reservoir, while a leaking heater core can contribute to coolant loss inside the cabin. Regular inspections and maintenance are crucial for identifying these issues early, ensuring that your vehicle remains in optimal condition and preventing costly repairs down the line.
Addressing a coolant leak in your 2010 INFINITI FX50 is of utmost importance due to the potential risks associated with engine overheating and subsequent damage. Coolant plays a vital role in maintaining optimal engine temperature; a leak can quickly lead to a drop in coolant levels, resulting in the engine running hotter than normal. This overheating can cause significant harm to engine components, leading to costly repairs or even complete engine failure if not resolved promptly. Moreover, a coolant leak may indicate underlying issues such as a damaged radiator or a failing water pump, which can exacerbate the situation if left unchecked. Therefore, it is crucial to inspect and repair any coolant leaks as soon as they are detected to ensure the vehicle operates safely and efficiently, ultimately protecting your investment and ensuring your safety on the road.
