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 2022 Lincoln Aviator, start by visually inspecting the area beneath your vehicle for any puddles of coolant, as this is often the most straightforward indication of a leak. Next, examine the hoses connected to the radiator and engine, looking for any visible cracks, holes, or loose connections that could be the source of the leak. Don’t overlook the radiator itself; check for signs of corrosion or leaks that may not be immediately apparent. If these initial checks do not reveal the problem, consider performing a pressure test on the cooling system, which can help pinpoint leaks that are not visible to the naked eye. Additionally, inspect the water pump for any signs of damage or leakage, as this component is crucial for maintaining proper coolant circulation. Pay attention to the heater core as well, especially if you detect a sweet smell inside the cabin, which can indicate a leak. Lastly, monitor the coolant level in the reservoir over time; a consistent drop may suggest a leak somewhere in the system. By following this methodical approach, you can effectively identify and address any coolant leak issues in your vehicle.
When dealing with coolant leaks in a 2022 Lincoln Aviator, it's essential to understand the common problems that can arise within the vehicle's cooling system. One of the primary culprits is damaged hoses, which can develop cracks or wear over time, leading to leaks. Additionally, a faulty radiator, whether due to corrosion or physical damage, can also contribute to coolant loss. The water pump, responsible for circulating coolant, may develop leaks if it becomes damaged, further exacerbating the issue. In more severe cases, a cracked engine block can result in significant coolant leaks, while a loose or damaged radiator cap can allow coolant to escape from the system. Lastly, worn-out gaskets, particularly the head gasket, can deteriorate and lead to leaks as well. Addressing these issues promptly is crucial to prevent overheating and potential engine damage, making it advisable to inspect and repair any suspected leaks with the help of a qualified mechanic.
Addressing a coolant leak in a 2022 Lincoln Aviator is of utmost importance due to the serious implications of neglecting this issue. Coolant plays a critical role in regulating engine temperature; without it, the engine is at risk of overheating, which can lead to catastrophic damage. If a leak is not promptly repaired, the engine may not maintain optimal operating temperatures, resulting in decreased performance and potential engine failure. Additionally, a coolant leak can compromise other components of the cooling system, such as the radiator and water pump, leading to more extensive and costly repairs. Ignoring the symptoms of a coolant leak not only jeopardizes the vehicle's functionality but also poses safety risks on the road. Therefore, it is crucial for owners to address any signs of a coolant leak immediately to ensure the longevity and safe operation of their Lincoln Aviator.
