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 2006 Dodge Stratus, start with a thorough visual inspection of the vehicle. Look beneath the car for any signs of coolant pooling or dripping, focusing on critical components such as the radiator, hoses, and water pump. If you don’t find any visible leaks, proceed to perform a pressure test on the cooling system, which can help identify hidden leaks by pressurizing the system and revealing weak points. Additionally, inspect the radiator cap for any damage, as a faulty cap can contribute to coolant loss. Pay close attention to the hoses connected to the cooling system; any cracks or bulges may indicate wear that could lead to leaks. Don’t forget to examine the water pump for signs of corrosion or leakage, as this is another common source of coolant issues. Finally, monitor the coolant level in the reservoir regularly; a significant drop without visible leaks may suggest an internal leak, such as a head gasket failure. By following this diagnostic approach, you can systematically identify and address coolant leaks, ensuring your vehicle remains in good working condition.
When dealing with coolant leaks in a 2006 Dodge Stratus, it's essential to understand the various potential sources of the problem. One of the most frequent culprits is a damaged radiator, which can develop cracks or corrosion over time, leading to coolant escaping. Additionally, a faulty radiator cap can disrupt the pressure within the cooling system, resulting in leaks. Worn-out hoses are another common issue; as they age, they may crack or become brittle, allowing coolant to seep out. The water pump, responsible for circulating coolant, can also leak, particularly if its seals are worn. In more severe cases, a cracked engine block may be the source of the leak, which requires immediate attention. Lastly, loose or damaged hose clamps can prevent a proper seal, causing coolant to leak from the connections. By being aware of these common causes, DIYers can better diagnose and address coolant leaks, ensuring their vehicle remains in good working condition.
Addressing a coolant leak in a 2006 Dodge Stratus is of utmost urgency due to the critical role coolant plays in maintaining engine temperature. When coolant leaks occur, they can lead to overheating, which poses a serious risk of damaging vital engine components. Ignoring this issue not only compromises the engine's integrity but can also result in costly repairs that could have been avoided with timely intervention. Furthermore, a coolant leak can diminish fuel efficiency and overall vehicle performance, making it essential to act quickly. By promptly addressing a coolant leak, you not only safeguard your vehicle's functionality but also ensure your safety on the road. Therefore, if you suspect a coolant leak, it is crucial to investigate and resolve the issue immediately to prevent further complications.
