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.
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 Stealth, it's essential to adopt a systematic diagnostic approach that begins with the most accessible components. Start by inspecting the hoses for any visible signs of wear, cracks, or leaks, as these are often the easiest to identify and repair. Next, examine the radiator for corrosion or leaks, which can be common culprits in coolant loss. If the hoses and radiator appear intact, turn your attention to the water pump, as it can also be a source of leaks. Pay special attention to the area where the engine and transmission connect, as leaks often occur here due to the complexity of the assembly. Additionally, don't overlook the water pipe O-rings located beneath the intake manifold, as these can deteriorate over time and lead to leaks. If you identify a leak, consider using a commercial stop leak product for minor issues, following the manufacturer's instructions carefully. For temporary fixes, duct tape or specialized radiator sealants can be effective until a permanent solution is implemented. If the coolant reservoir shows signs of cracks, replacing it is advisable, as repairs can be challenging and unreliable. By following this methodical approach, you can effectively diagnose and address coolant leaks in your Dodge Stealth, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a Dodge Stealth, it's essential to understand the common problems that can arise within the cooling system. One of the most frequent culprits is a leaking radiator hose, which can develop cracks or become loose over time, leading to significant coolant loss. Additionally, a malfunctioning water pump can fail to circulate coolant properly, resulting in leaks and potential overheating. Other issues may stem from a bad thermostat housing or a worn intake manifold gasket, both of which can compromise the integrity of the cooling system. It's also important to consider the condition of the radiator itself, as damage or corrosion can create leaks, while a faulty heater core may lead to coolant seeping into the cabin. Lastly, a blown head gasket is a serious concern that can cause coolant to mix with engine oil, leading to severe engine damage if not addressed promptly. By being aware of these common problems, DIYers can more effectively diagnose and tackle coolant leaks in their Dodge Stealth, ensuring a reliable and efficient vehicle.
Addressing a coolant leak in your Dodge Stealth is not just a matter of routine maintenance; it is a critical step in ensuring the longevity and safety of your vehicle. Ignoring the symptoms of a coolant leak can lead to severe engine overheating, which poses a serious risk of engine seizure and catastrophic failure. This not only jeopardizes your safety on the road but can also result in extensive and costly repairs that could have been easily avoided with timely intervention. Furthermore, a coolant leak can significantly impact your vehicle's performance and fuel efficiency, leading to a frustrating driving experience and increased operational costs. By staying vigilant and addressing any signs of a coolant leak promptly, you can protect your investment, maintain optimal performance, and ensure a safer driving experience.
