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 2013 Dodge Dart, begin by checking the coolant level and its condition, as low levels can indicate a leak. Next, conduct a visual inspection of the cooling system, focusing on the coolant reservoir, radiator, hoses, and engine connections for any signs of fluid spills or corrosion. If no obvious leaks are found, perform a cooling system pressure test, which can help pinpoint the leak's location by monitoring pressure drops while the engine runs. Pay special attention to the connections between hoses and the engine, as these are common leak points; look for cracks or loose fittings. Additionally, inspect for external leaks around the radiator and water pump, using a flashlight for better visibility. While driving, keep an eye on the engine temperature gauge, as unexpected rises may signal a coolant leak. Always prioritize safety by wearing gloves and safety glasses when handling coolant, which is toxic. By following this systematic approach, you can accurately diagnose and address any coolant leaks, preventing potential engine damage.
When dealing with coolant leaks in a 2013 Dodge Dart, it's essential to understand the common problems that can arise within the cooling system. One frequent culprit is the coolant reservoir, where leaks can occur from the overflow tank. If you notice coolant pooling under your vehicle, inspecting and potentially replacing the overflow tank can help maintain a proper seal and prevent pressure issues. Additionally, pay close attention to the hoses and connections, particularly where they meet the engine or radiator. These areas are prone to leaks, and a simple hose clamp can serve as a temporary fix until a more permanent solution is implemented. The radiator itself is another critical component to examine; any visible cracks or damage can lead to significant coolant loss. Furthermore, the hoses throughout the cooling system can deteriorate over time, especially at connection points, making regular inspections vital. Lastly, be aware that pressure buildup within the system can exacerbate leaks, particularly if seals are worn or components are damaged. Addressing these issues promptly is crucial, as neglecting coolant leaks can lead to severe engine overheating and costly repairs.
Addressing a coolant leak in a 2013 Dodge Dart is of utmost urgency due to the severe consequences that can arise from neglecting this issue. A coolant leak, if left unattended, can lead to significant engine damage, including overheating, which may result in cracked cylinder heads or blown head gaskets. These repairs can be costly and time-consuming, not to mention the potential for complete engine failure. The most common locations for leaks in this model include the connections between hoses and the engine or radiator, as well as the coolant reservoir itself. To mitigate these risks, it is essential to locate the source of the leak promptly. Regularly checking the coolant level and monitoring the temperature gauge can provide early warnings of overheating. If you suspect a leak, take immediate action by inspecting hoses and connections, and consider replacing any faulty components. Remember to prioritize safety by wearing protective gear when handling coolant, as it is toxic. By addressing a coolant leak swiftly, you can safeguard your engine's health and ensure the reliable performance of your vehicle.
