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.
To effectively diagnose a coolant leak in your 2008 Chrysler Sebring, start with a thorough visual inspection under the hood and beneath the vehicle. Look for any signs of coolant, such as puddles or wet spots, particularly around hoses, connections, and the radiator. Next, check the coolant level in both the reservoir and radiator; a significant drop can indicate a leak. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system, which can help pinpoint leaks by pressurizing the system with air. Additionally, inspect all hoses, clamps, and connections for wear or damage, as these are common culprits for leaks. Don’t forget to examine the radiator for any signs of corrosion or damage, and check the water pump for leaks as well. Finally, be alert for any steam or a sweet smell while driving, as these can also signal a coolant leak. By following these steps, you can systematically identify the source of the coolant leak and take appropriate action.
When dealing with coolant leaks in a 2008 Chrysler Sebring, it's essential to understand the common problems that may arise within the vehicle's cooling system. One of the primary culprits is a damaged radiator, which can develop corrosion over time, leading to leaks. Additionally, a faulty water pump can also be a significant source of coolant loss, as it is responsible for circulating coolant throughout the engine. Worn-out hoses are another frequent issue; as they age, they can crack or become brittle, resulting in leaks. It's also crucial to check the hose clamps, as loose or damaged clamps may fail to secure the hoses properly, allowing coolant to escape. In more severe cases, a cracked engine block can lead to substantial coolant leaks, which can be detrimental to engine health. Lastly, a leaking heater core can cause coolant to seep into the vehicle's interior, creating a damp environment and potentially leading to further complications. Addressing these issues promptly through regular maintenance and inspections can help prevent overheating and protect your engine from damage.
Addressing a coolant leak in a 2008 Chrysler Sebring is of utmost urgency due to the significant risks associated with engine overheating and potential damage. Coolant plays a vital role in maintaining optimal engine temperature; a leak can lead to insufficient coolant levels, causing the engine to overheat. This overheating can result in severe damage to engine components, including warped heads or a blown gasket, which can lead to costly repairs. Furthermore, neglecting a coolant leak can diminish the vehicle's overall performance, leading to decreased fuel efficiency and increased wear on other engine parts. In some instances, a coolant leak may indicate more serious underlying issues, such as a cracked radiator or a failing head gasket, which require immediate professional attention. Therefore, it is crucial for DIY enthusiasts to diagnose and repair any coolant leaks promptly to ensure the safe operation of their vehicle and to avoid more extensive and expensive repairs in the future.
