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.
When troubleshooting coolant leaks in a Dodge Stratus, it's essential to adopt a methodical diagnostic approach. Begin by visually inspecting the engine bay and under the vehicle for any obvious signs of leaks, such as puddles of coolant or a sweet smell, which can indicate a leak's presence. Check the condition of the hoses and connections, as loose or cracked hoses are often the culprits behind leaks. If no visible issues are found, conduct a cooling system pressure test to pinpoint the leak's location, as this can reveal hidden problems like a failing water pump or a damaged radiator. Additionally, ensure that the electric cooling fan is functioning correctly and that there are no obstructions in the radiator. By systematically addressing these potential issues, you can effectively identify and resolve coolant leaks, ensuring your Dodge Stratus remains in optimal condition.
When tackling coolant leaks in a Dodge Stratus, it's essential to understand the common problems that can arise within the cooling system. One frequent issue is the deterioration of rubber hoses, which can become brittle over time and develop cracks, leading to leaks. Additionally, the radiator itself may corrode or sustain damage from road debris, resulting in coolant escaping. Another potential culprit is the water pump, which can fail due to wear and tear, causing leaks at the seals. It's also important to consider the possibility of a blown head gasket, which can lead to coolant mixing with engine oil, a more serious issue that requires immediate attention. By being aware of these common failure modes, you can more effectively diagnose the source of the leak and take the necessary steps to repair or replace the affected components, ensuring your Dodge Stratus remains in optimal condition.
Addressing a coolant leak in your Dodge Stratus is not just a matter of routine maintenance; it is a critical step in ensuring the safety and longevity of your vehicle. Ignoring a coolant leak can lead to severe engine overheating, which may result in catastrophic engine damage or even complete failure. As the coolant level drops, the engine's ability to regulate temperature diminishes, increasing the risk of overheating and subsequent performance issues. Moreover, a coolant leak can signal deeper problems, such as a failing radiator or damaged hoses, which, if left unaddressed, can escalate into more costly repairs. Regularly monitoring for coolant leaks and addressing them promptly not only preserves your engine's health but also enhances fuel efficiency and overall vehicle performance. By taking immediate action, you can avoid the safety hazards associated with an overheating engine and ensure that your Dodge Stratus remains reliable on the road.
